Question 1Bus Passengers

According to Article 51 of the Road Traffic Safety Law of the PRC and safety standards for passenger vehicles (GB 7258-2017), what is the mandatory pre-departure safety duty of a commercial passenger bus driver regarding seatbelts?

  1. The driver must remind and ensure that all passengers have fastened their seatbelts before moving the vehicle and maintain reminders throughout the journey Correct answer.
  2. The driver only needs to remind passengers sitting in the front row and seats next to emergency exits to wear seatbelts
  3. The driver is only required to broadcast a seatbelt reminder when entering expressways or mountain roads
  4. The driver does not need to verify seatbelts if the bus is equipped with passenger airbags

Explanation

Under Article 51 of the Road Traffic Safety Law and Ministry of Transport passenger transport regulations, commercial bus drivers are legally obligated to implement the 'full journey, all passengers' (全程全员) seatbelt protocol. The driver must inspect and verbally remind all passengers to properly fasten seatbelts before departing the station or bus bay and reiterate the rule throughout transit. Airbags and seat positions do not exempt any passenger from wearing safety belts.

Question 2Bus Passengers

According to Article 62 of the Regulations for the Implementation of the Road Traffic Safety Law of the PRC, which of the following rules strictly applies to passenger vehicle doors during transit?

  1. Doors may remain slightly ajar on hot summer days if the air conditioning is insufficient
  2. Vehicles must not be moved or driven if passenger doors are not completely closed (车门未关好不准起步) Correct answer.
  3. Rear exit doors may be opened in advance while gliding into a bus stop to speed up passenger turnaround
  4. The driver may allow passengers to push open pneumatic doors while slowing down at red traffic lights

Explanation

Article 62(1) of the Road Traffic Safety Law Implementation Regulations explicitly prohibits drivers from moving or operating a motor vehicle when doors or compartments are not fully closed ('车门、车厢没有关好时，不准起步和行驶'). Opening passenger doors before the bus has come to a complete standstill frequently leads to fatal fall accidents.

Question 3Bus Passengers

Why must passenger bus drivers maintain exceptionally smooth acceleration, gear shifting, and progressive deceleration rather than aggressive driving dynamics?

  1. Buses carry high centers of gravity and unrestrained/standing passengers whose inertia during abrupt braking or swerving causes severe fall injuries Correct answer.
  2. Aggressive acceleration causes the bus engine transmission to automatically lock into reverse gear
  3. Smooth driving is only required when transport management bureau inspectors are physically onboard the coach
  4. Sudden braking reduces pneumatic air tank pressure to zero within three seconds, permanently disabling the steering wheel

Explanation

Commercial passenger buses have a high center of gravity and carry standing or elderly passengers whose stability is vulnerable to rapid changes in acceleration. Abrupt braking generates high inertial forces that throw passengers forward against partitions or down aisles, which is one of the leading causes of non-collision passenger injuries in public transit.

Question 4Bus Passengers

When assisting elderly passengers, pregnant women, or passengers with limited mobility who are boarding a city bus, what is the driver's proper civilized practice?

  1. Close the door immediately after the passenger steps on the first step and accelerate to keep on schedule
  2. Wait patiently until the vulnerable passenger is fully seated or securely holding a safety handrail before closing doors and starting smoothly Correct answer.
  3. Honk the horn to urge other seated passengers to leave their seats immediately
  4. Instruct the mobility-impaired passenger to board through the rear exit door while the bus is moving

Explanation

Civilized passenger transit standards dictate that drivers must exercise patience when vulnerable passengers (elderly, pregnant, children, disabled) board. The driver must ensure the passenger is securely seated or gripping handrails before closing the doors and smoothly starting the vehicle, preventing sudden start-up falls.

Question 5Bus Passengers

Before pulling away from a bus stop, why must a bus driver thoroughly check the right-side external rearview mirror and blind-spot convex mirrors (下视镜/补盲镜)?

  1. To check whether any late passengers, children, or non-motorized vehicles are trapped in the blind spot near the front or rear wheels Correct answer.
  2. To inspect whether the vehicle's paint has faded during the stop
  3. To ensure that oncoming vehicles in the opposite traffic lane are yielding
  4. To verify that the bus advertising panels are facing the curb

Explanation

Large buses have extensive blind spots on their right side, particularly around the front passenger door and right front wheel arch. Checking the wide-angle and blind-spot mirrors ensures that rushing pedestrians, lingering children, or overtaking cyclists are not positioned in dangerous proximity to the wheels before starting.

Question 6Bus Passengers

Which of the following items must be verified during a commercial bus driver's daily pre-trip safety inspection (出车前检查)?

  1. Tire pressure and tread condition, service/parking brakes, steering functionality, fire extinguishers, emergency hammers, and clear emergency exit pathways Correct answer.
  2. Only the exterior cleanliness and passenger fare collection box
  3. Only the audio system volume and destination digital LED sign
  4. The vehicle fuel level only, leaving all mechanical inspections to the annual inspection station

Explanation

Under the Safety Specifications for Power-driven Vehicles Operating on Roads (GB 7258-2017) and transport safety management protocols, commercial bus drivers must conduct a daily pre-trip walkaround check. This includes verifying tire condition, braking and steering systems, lighting, emergency safety hammers, fire extinguisher pressure gauges, and ensuring that emergency doors and aisles are completely unobstructed.

Question 7Bus Passengers

According to Article 78 of the Regulations for the Implementation of the Road Traffic Safety Law of the PRC, what is the maximum statutory speed limit for large passenger buses (大型客车) operating on expressways under normal weather conditions?

  1. 100 km/h (whereas small passenger cars may travel up to 120 km/h) Correct answer.
  2. 120 km/h (identical to small passenger cars)
  3. 80 km/h on all expressway lanes
  4. 130 km/h on three-lane expressways

Explanation

Under Article 78 of the Implementation Regulations, the maximum speed limit for large passenger buses (and medium buses) on expressways is capped at 100 km/h, even when the overall road speed limit for small passenger cars is 120 km/h. This speed restriction accounts for the longer braking distances and rollover risks associated with large passenger coaches.

Question 8Bus Passengers

When driving a large passenger coach into a sharp bend or mountain curve, what is the correct vehicle handling technique to ensure passenger safety?

  1. Accelerate sharply while entering the curve to counter centrifugal force with momentum
  2. Decelerate smoothly before entering the bend ('slow in, smooth out' / 减速慢行), select an appropriate gear, and maintain a steady steering radius without jerky corrections Correct answer.
  3. Coast through the curve in neutral (空挡) while applying intermittent handbrake pressure
  4. Steer across into the opposing oncoming lane to straighten the curve radius at high speed

Explanation

Centrifugal force increases with the square of vehicle speed. Because buses have a high center of gravity, drivers must complete braking and gear selection before the curve ('slow in'), smoothly steer through the curve within their own lane, and gently accelerate only after the vehicle begins straightening out ('smooth out').

Question 9Bus Passengers

According to the Road Transport Regulations of the PRC, how should a passenger bus driver handle suspicions that a boarding passenger is carrying flammable, explosive, or hazardous materials?

  1. Ignore it as long as the passenger promises not to open the package during the journey
  2. Politely request an inspection, strictly refuse carriage of prohibited dangerous goods, and report the matter to station security or the police if the passenger refuses compliance Correct answer.
  3. Instruct the passenger to place the flammable items on the rear roof rack
  4. Charge an extra freight surcharge and allow the passenger to board

Explanation

Carrying hazardous materials (flammables, explosives, toxic chemicals, fireworks) on passenger transport vehicles is strictly forbidden by law. The driver and conductor have the statutory duty and authority to inspect suspicious luggage, refuse transportation, and notify police authorities to ensure collective passenger safety.

Question 10Bus Passengers

Under Ministry of Transport regulations on vehicle dynamic monitoring (道路运输车辆动态监督管理办法), what is the driver's legal obligation regarding the onboard satellite positioning and driver monitoring system (GPS/北斗/DMS)?

  1. The driver must ensure the dynamic monitoring device is operating normally throughout the trip and must never block, tamper with, or power off the system Correct answer.
  2. The driver may power off the GPS system during night driving to preserve battery power
  3. The driver may place a sticker over the in-cabin driver-facing camera if feeling uncomfortable
  4. Dynamic positioning devices are optional and only need to be turned on when entering unfamiliar cities

Explanation

Under the Regulations on Dynamic Supervision and Management of Road Transport Vehicles, satellite positioning and intelligent video monitoring devices must remain continuously powered and functioning normally while in operation. Tampering with, shielding, disconnecting, or intentionally blocking cameras or positioning devices incurs severe administrative penalties and driving credential demerits.

Question 11Bus Passengers

When operating a passenger coach in winter on hard-packed snow or icy mountain passes, what is the proper protocol regarding anti-skid tire chains (防滑链)?

  1. Install certified anti-skid chains on the driving wheels (驱动轮) prior to encountering icy sections, drive at reduced speeds, and maintain extended following distances Correct answer.
  2. Install anti-skid chains only on the non-driven front steering wheels
  3. Drive at 80 km/h with chains on dry pavement to break up road ice ahead
  4. Inflate tires to maximum pressure and avoid using any chains

Explanation

Anti-skid tire chains must be fitted to the driving axle wheels (驱动轮) to provide mechanical traction on packed snow and ice. Chains should be mounted before reaching hazardous icy gradients, speed must be kept low (typically below 30 km/h), and chains must be removed once returning to clear dry pavement to avoid road and tire damage.

Question 12Bus Passengers

When driving a commercial passenger bus in high-altitude plateau regions (such as Qinghai-Tibet plateau highways), what physical vehicle changes must the driver anticipate?

  1. Atmospheric pressure drops, reducing engine oxygen intake (causing engine power drop) and lowering the boiling point of coolant; brake heating increases during descents Correct answer.
  2. Atmospheric pressure increases, causing the engine to gain 50% more horsepower
  3. Tire pressure automatically drops to zero due to thin air
  4. Plateau air eliminates the risk of brake fade entirely

Explanation

At high altitudes, low atmospheric pressure reduces air density, decreasing diesel engine volumetric efficiency and power output. Furthermore, lower atmospheric pressure reduces the boiling point of unpressurized water/coolant, making engine overheating more frequent, while long mountain grades demand rigorous engine and retarder brake management.

Question 13Bus Passengers

When approaching a highway road construction zone (施工路段) marked with advance warning signs, lane closures, and guide arrows, what should the bus driver do?

  1. Observe advance warning signs, decelerate early, merge smoothly into the open travel lane in advance, obey flagger/sign instructions, and refrain from overtaking in the construction area Correct answer.
  2. Accelerate to the very end of the closed lane and force-merge into the open lane at the last second
  3. Drive through the orange traffic cone barrier onto the unpaved construction surface to bypass traffic
  4. Honk continuously to demand that construction workers clear the closed lane immediately

Explanation

Approaching work zones requires proactive deceleration, early lane merging according to lane transition signs, strict adherence to posted lower construction speed limits, and yielding to construction personnel and equipment without aggressive late merging or barrier intrusions.

Question 14Bus Passengers

In extreme sub-zero winter conditions, why must a bus driver regularly drain moisture from the pneumatic air brake reservoir tanks (储气筒放水)?

  1. Condensed water in air tanks can freeze into ice inside pneumatic brake valves, air pipes, and relay valves, causing complete air brake failure Correct answer.
  2. Water accumulation increases the bus's curb weight by over 5 metric tons
  3. Water in air tanks causes the bus alternator to short-circuit through the tires
  4. Air tanks must be drained so they can be filled with liquid anti-freeze oil daily

Explanation

Compressed air contains water vapor that condenses in air brake reservoir tanks. In sub-zero winter temperatures, accumulated water freezes into ice plugs inside brake valves, four-circuit protection valves, and brake chambers, completely disabling the pneumatic braking system. Regular manual or automatic draining is vital for winter brake safety.

Question 15Bus Passengers

If a bus's electrical system burns out during a fire, disabling the dashboard pneumatic door control buttons, how should the driver and passengers open the passenger doors?

  1. Operate the manual pneumatic emergency door release valve (应急阀 / 应急开关) located near the door frame (turn or pull as labeled) to vent air pressure and push the doors open manually Correct answer.
  2. Wait for the pneumatic air tanks to completely explode to blow the doors open
  3. Use cigarette lighters to melt the rubber door seals
  4. Pneumatic doors cannot be opened without electricity under any circumstances

Explanation

Under GB 7258-2017, all passenger buses with power-operated passenger doors must be equipped with manual emergency door release valves (应急阀) both inside (near the door headers/steps) and outside the vehicle. Operating this valve vents air pressure from the door actuator cylinders, allowing the doors to be easily pushed open by hand.

Question 16Bus Passengers

When using an emergency safety hammer (安全锤) to break tempered glass side windows on a passenger bus during an evacuation, what is the correct striking technique?

  1. Use the pointed steel tip of the hammer to strike firmly at the four corners or edges of the tempered glass at a 90-degree angle, then push the shattered glass outward Correct answer.
  2. Strike lightly at the exact dead center of the glass pane with the flat plastic handle
  3. Scrape the hammer gently across the window tint film in a circular pattern
  4. Safety hammers should only be used to hit the metal window pillars, not the glass

Explanation

Tempered safety glass (钢化玻璃) has its highest structural stress concentration at its four corners and edges, while its center possesses the greatest elasticity. Striking firmly at the four corners with the pointed tungsten-steel tip concentrates kinetic impact energy, shattering the entire pane into dull granules that can be pushed outward.

Question 17Bus Passengers

How should passengers and drivers operate the roof escape hatch / emergency skylight (车顶逃生天窗) when bus side doors and windows are blocked?

  1. Remove the protective cover, rotate/pull the red emergency release handle as indicated by arrows, and push the hatch panel firmly upward and outward to create an escape opening Correct answer.
  2. Use a safety hammer to smash through the metal roof structure next to the hatch
  3. Roof hatches are strictly for air ventilation and cannot be opened during emergencies
  4. Wait for outside rescue personnel to cut the roof open with hydraulic torches

Explanation

Bus roof escape hatches (车顶安全出口) serve as statutory emergency egress portals (especially during rollovers or water immersion). Operating the red emergency release handle disengages the latch mechanism, allowing the entire hatch panel to be pushed upward and outward, providing a large exit pathway.

Question 18Bus Passengers

What is an emergency runaway truck escape ramp (避险车道) and how should a bus driver with failed brakes utilize it?

  1. An uphill escape ramp filled with deep gravel/sand arrester beds situated on steep downhill descents; the driver should steer squarely into the center of the gravel bed to dissipate vehicle kinetic energy safely Correct answer.
  2. A paved lane designed for buses to overtake slow-moving trucks at high speed
  3. A scenic rest stop where passengers can take photographs of the valley
  4. A toll booth lane reserved for overweight commercial vehicles

Explanation

Runaway vehicle escape ramps (避险车道) are specialized safety facilities built on the right side of steep mountain descents. They feature an upward gradient and a thick bed of loose gravel or sand that rapidly absorbs kinetic energy and safely brings runaway vehicles to a complete stop without rolling over.

Question 19Bus Passengers

If the steering linkage suddenly fails or breaks on a moving passenger coach, what is the driver's primary emergency reaction?

  1. Immediately release the accelerator, apply progressive brake pedal pressure (or emergency braking if collision is imminent), activate hazard flashers, and honk to warn other traffic Correct answer.
  2. Slam the accelerator pedal to the floor to power through the steering loss
  3. Turn off all exterior lights to conserve electrical power
  4. Instruct all passengers to shift their body weight to the right side of the bus

Explanation

When mechanical steering fails, the vehicle will continue along its current trajectory or drift toward road crown angles. The driver must instantly release the throttle, apply progressive and firm braking to stop the vehicle in the shortest possible distance, and use hazard flashers and horn to alert surrounding traffic.

Question 20Bus Passengers

If a strong burning electrical or plastic smell is detected in the cabin while driving a passenger bus, what must the driver do immediately?

  1. Pull over immediately in a safe location, stop, turn off the engine ignition, disconnect the master electrical battery switch, evacuate passengers, and inspect electrical wiring harnesses with a fire extinguisher at hand Correct answer.
  2. Turn the cabin heater and air conditioning blower to maximum speed to blow the smell away
  3. Continue driving to the final destination while opening all windows
  4. Pour water directly over the dashboard fuse box while driving

Explanation

A burning electrical smell indicates wire insulation overheating or electrical short circuits, which is a primary trigger for catastrophic bus fires. The driver must immediately stop, shut off power via the master battery switch (to de-energize circuits and prevent arc ignition), evacuate passengers, and investigate with an extinguisher ready.

Question 21Bus Passengers

When a passenger bus rear axle begins to side-slip (skid) to the right on a slippery road, what is the correct steering correction technique?

  1. Gently steer toward the right (the direction of the skid), ease off the accelerator, and avoid slamming on the brakes until the vehicle regains traction Correct answer.
  2. Jerk the steering wheel violently to the far left and slam on the emergency brake
  3. Accelerate to maximum speed while pulling the handbrake
  4. Turn off the engine and let the steering wheel spin freely

Explanation

To recover from a rear-wheel skid (oversteer), the driver must steer smoothly in the direction the rear wheels are sliding (if the rear slides right, steer right). This aligns the front rolling wheels with the vehicle's momentum. Slamming on brakes or overcorrecting violently will spin the vehicle out completely.

Question 22Bus Passengers

What is the purpose of the engine compartment automatic fire suppression system (发动机舱自动灭火装置) installed on modern passenger buses under GB 7258-2017?

  1. To automatically detect high temperatures or open flames in the engine bay and discharge ultra-fine dry powder or aerosol extinguishing agent, with an optional manual cockpit trigger Correct answer.
  2. To spray cold fuel over the engine block to reduce fuel consumption
  3. To extinguish cigarette smoke inside the passenger luggage racks
  4. To spray water onto the exterior passenger door handles

Explanation

GB 7258-2017 mandates automatic fire extinguishing systems in the engine compartments of large passenger vehicles. These systems utilize thermal detection lines or flame sensors to automatically flood the engine bay with dry chemical powder or aerosol agents within seconds of a fire outbreak, suppressing fires before they breach the passenger cabin.

Question 23Bus Passengers

If the accelerator pedal on a passenger coach becomes mechanically jammed or stuck in the full-throttle position while driving, what is the correct emergency response?

  1. Depress the clutch pedal (or shift automatic transmission into Neutral 'N'), apply progressive foundation braking, steer the bus to the shoulder, stop, and switch off the ignition key Correct answer.
  2. Turn off the ignition key instantly while traveling at 100 km/h and lock the steering column
  3. Pump the accelerator pedal repeatedly while steering into opposing traffic
  4. Unbuckle the seatbelt and crawl into the footwell while driving to pull the pedal by hand

Explanation

When an accelerator pedal sticks, the driver must instantly disconnect engine power from the drive wheels by shifting to Neutral ('N') or depressing the clutch, apply firm service brakes to stop the vehicle on the roadside, and switch off the ignition once safe. Turning off the key while moving at speed risks locking the steering wheel column.

Question 24Bus Passengers

Under GA 1026 and GB 7258-2017 standards, what are the statutory requirements regarding emergency safety hammers (安全锤) on passenger coaches?

  1. Emergency safety hammers must be fully equipped in specified quantities, mounted securely in clearly visible, easily accessible positions next to emergency exit windows, and equipped with anti-theft alarms or functional pointed steel heads Correct answer.
  2. Safety hammers may be locked in the driver's private toolbox under the front seat
  3. Only one safety hammer is required per 50-passenger coach
  4. Safety hammers can be replaced with plastic beverage bottles

Explanation

GB 7258-2017 specifies that commercial passenger buses must be equipped with multiple safety hammers mounted adjacent to designated emergency side windows. Hammers must be clearly marked, unobstructed, and readily accessible to passengers at all times to enable rapid egress during fires or rollovers.

Question 25Bus Passengers

If an emergency passenger door becomes jammed in its frame following a moderate side collision, how can passengers create an alternative egress route?

  1. Utilize safety hammers to break emergency side windows, open the roof escape hatch, or use the driver compartment door/front windshield if intact Correct answer.
  2. Wait patiently in their seats without attempting any egress until tow trucks arrive
  3. Attempt to dismantle the engine cylinder head with bare hands
  4. Set fire to the seats to alert passing traffic

Explanation

When primary passenger doors are deformed and jammed after a collision, passengers must immediately utilize alternative statutory emergency exits: shattering side windows with emergency hammers, pushing open the roof escape hatch, or exiting through unjammed driver doors or emergency window portals.

Question 26Bus Passengers

If an aggressive passenger attempts to grab the steering wheel or assault the driver while a bus is moving, what is the driver's statutory operational protocol?

  1. Maintain emotional composure, firmly grip the steering wheel, immediately decelerate smoothly, pull over and park safely in a non-hazardous spot, engage the parking brake, activate hazard lights, and immediately call 110 police Correct answer.
  2. Abandon the steering wheel immediately and engage in a fistfight with the passenger while moving
  3. Accelerate to 100 km/h and intentionally crash into a tree to teach the passenger a lesson
  4. Open the passenger door and push the passenger out onto the road at high speed

Explanation

Driver safety protocols dictate that when subjected to passenger interference or assault, the driver must prioritize collective vehicle safety: hold the steering wheel firmly, decelerate immediately, bring the bus to a complete stop in a safe roadside location, apply the handbrake, turn on hazard lights, and contact 110 police while protecting passengers.

Question 27Bus Passengers

Under Ministry of Transport standard JT/T 1240-2019, what is the purpose and structural requirement of the driver safety protective partition (城市公共汽电车驾驶区防护隔离设施) installed on city buses?

  1. To provide a physical protective barrier around the driver's cockpit that prevents unauthorized passenger intrusion and physical assault while maintaining forward visibility, communication, and climate circulation Correct answer.
  2. To completely soundproof the driver so they cannot hear passenger requests
  3. To store heavy tools and passenger luggage around the driver's feet
  4. To prevent the driver from looking in the rearview mirrors

Explanation

JT/T 1240-2019 standardizes protective isolation doors/cages around the driver's cockpit on urban public transport buses. The partition features high-strength impact-resistant transparent safety glass and locking mechanisms that prevent violent passengers from reaching steering controls or assaulting the driver, while preserving necessary visibility and communication.

Question 28Bus Passengers

When faced with an emotionally agitated passenger shouting verbal abuse or making unreasonable route demands, how should a professional bus driver handle the situation?

  1. Remain calm, use polite and firm professional language, focus visual and mental attention strictly on driving safety, and stop safely to contact dispatch or police if the passenger threatens safe operation Correct answer.
  2. Scream insults back at the passenger using the onboard public address microphone
  3. Turn around to glare at the passenger while speeding through red lights
  4. Slam on the brakes repeatedly to shake the passenger off their feet

Explanation

Professional de-escalation requires emotional restraint. The driver must maintain calm, polite, and standardized communication ('克制忍让，文明服务'), keep attention focused on road safety, and, if the dispute escalates to threaten driving safety, pull over safely and seek police (110) or dispatch assistance.

Question 29Bus Passengers

When utilizing an Automated External Defibrillator (AED / 自动体外除颤器) to assist a passenger in sudden cardiac arrest, what is the critical safety rule during rhythm analysis and shock delivery?

  1. Ensure that NO ONE touches the patient ('Everyone clear' / 所有人离开) while the AED is analyzing heart rhythm and administering the electric shock Correct answer.
  2. All passengers must hold the patient's hands tightly during the shock delivery
  3. The AED should only be used while the bus is traveling at high speed on an expressway
  4. The electrode pads should be attached over the patient's thick winter coat

Explanation

When an AED analyzes cardiac rhythm or delivers an electrical defibrillation shock, the rescuer must loudly call out 'Stand clear!' and ensure that no person is in physical contact with the victim. Physical contact interferes with rhythm analysis and risks conducting high-voltage electrical shock to bystanders.

Question 30Bus Passengers

When a passenger experiences severe motion sickness (晕车) with nausea, pale complexion, and cold sweats, what practical assistance should the bus driver and crew provide?

  1. Provide clean vomit bags, adjust cabin fresh air ventilation, maintain exceptionally smooth driving without jerky acceleration/braking, and suggest the passenger look toward the distant horizon Correct answer.
  2. Accelerate aggressively through corners to test the passenger's balance
  3. Lock the passenger in the underfloor luggage compartment
  4. Force the passenger to drink three cups of heavy cooking oil

Explanation

Motion sickness arises from visual-vestibular sensory conflict. Providing fresh air ventilation, offering clean vomit bags, smoothing out driving dynamics (avoiding jerky braking and sharp swerves), and advising the passenger to focus on stable distant horizons alleviates vestibular mismatch.

Question 31China Road Framework

Under Ministry of Public Security (MPS) Order No. 162, what is the regulation regarding mobile phone usage by commercial bus drivers while operating a vehicle?

  1. Drivers may make handheld phone calls if driving at speeds under 30 km/h in urban bus lanes
  2. Drivers are strictly prohibited from answering handheld calls, texting, watching video streams, or browsing devices while operating the vehicle Correct answer.
  3. Drivers may send voice messages as long as both hands remain placed at the top of the steering wheel
  4. Handheld phone calls are permitted as long as the conversation pertains directly to bus route scheduling

Explanation

Under MPS Order No. 162 and the Road Traffic Safety Law, driving while operating a handheld mobile phone, texting, or watching digital media incurs demerit points and administrative fines. For commercial passenger drivers, zero distraction is strictly enforced because cognitive, manual, and visual distractions drastically increase reaction times and crash risks.

Question 32China Road Framework

According to Article 47 of the Road Traffic Safety Law of the PRC, when a passenger bus approaches a crosswalk (pedestrian crossing) where pedestrians are crossing, what must the driver do?

  1. Accelerate and honk to urge pedestrians to clear the crossing quickly
  2. Stop the vehicle before the stop line and yield right-of-way until pedestrians have passed safely (减速停车，避让行人) Correct answer.
  3. Maneuver around pedestrians through the opposing lane to maintain bus timetable punctuality
  4. Flash high beams continuously and proceed as long as pedestrians are not directly in front of the bumper

Explanation

Article 47 mandates that when a motor vehicle approaches a crosswalk, it must slow down; if pedestrians are passing through the crosswalk, the vehicle must stop and yield right-of-way ('遇行人正在通过人行横道，应当停车让行'). Professional bus drivers must set an example of civilized yielding to protect vulnerable pedestrians.

Question 33China Road Framework

According to Article 46 of the Road Traffic Safety Law of the PRC, how must a commercial passenger bus navigate an uncontrolled railway level crossing (无人看守的铁路道口)?

  1. Accelerate to cross the tracks as rapidly as possible before any train appears
  2. Come to a complete stop before the tracks, look left and right, listen carefully, select a low gear, and cross steadily without shifting gears or stopping on the tracks ('一停、二看、三通过') Correct answer.
  3. Follow the preceding vehicle closely bumper-to-bumper across the tracks
  4. Honk continuously and coast over the tracks in neutral gear

Explanation

At uncontrolled railway crossings, passenger vehicles must execute the mandatory 'Stop, Look, and Pass' ('一停、二看、三通过') procedure: stop before the stop line, look both ways, listen for train horns, engage a low gear, and proceed steadily across the tracks without shifting gears or stopping.

Question 34China Road Framework

When approaching a highway tunnel entrance during bright daytime conditions, what visual phenomenon occurs and how should the bus driver respond?

  1. The 'black hole effect' (黑洞效应) causes temporary visual impairment; the driver must reduce speed and turn on low-beam headlights before entering the tunnel Correct answer.
  2. The 'white hole effect' occurs; the driver must put on dark sunglasses and accelerate into the tunnel
  3. Tunnels have no lighting changes; drivers should maintain maximum expressway cruising speed
  4. The driver should turn on high beams and hazard flashers while honking continuously

Explanation

Entering a dark tunnel from bright daylight produces the 'black hole effect' because human eyes require adaptation time to adjust to diminished luminance. Drivers must decelerate in advance, turn on low-beam headlights before entry, and refrain from sudden maneuvers while visual adaptation takes place.

Question 35China Road Framework

Under Article 48 of the Road Traffic Safety Law Implementation Regulations, when two vehicles meet on a narrow mountain slope where passing is difficult, which vehicle has the statutory right-of-way?

  1. The vehicle traveling uphill has right-of-way; however, if the downhill vehicle is already halfway down the slope and the uphill vehicle has not begun climbing, the downhill vehicle goes first Correct answer.
  2. The downhill vehicle always has absolute right-of-way regardless of position
  3. The larger passenger bus must always force smaller vehicles into the ditch
  4. Whichever vehicle flashes its high beams first has statutory right-of-way

Explanation

Article 48(3) specifies that on narrow mountain slopes, the uphill vehicle has priority because stopping and restarting uphill is difficult and risks rolling backward. However, if the downhill vehicle has already reached halfway down the slope before the uphill vehicle starts climbing, the downhill vehicle is permitted to proceed first.

Question 36China Road Framework

During high summer temperatures, what is the major risk regarding passenger bus tires, and what is the strictly prohibited response to an overheated, high-pressure tire?

  1. Tire internal temperature and air pressure rise significantly, increasing blowout risks; drivers must NEVER deflate (放气) or pour cold water (浇冷水) on hot tires, but must stop in shade to let them cool naturally Correct answer.
  2. Tires lose pressure in hot weather; drivers must immediately pump 50% more air into hot tires
  3. Drivers must splash buckets of ice water directly onto red-hot brake drums and tires while driving
  4. High tire pressure is beneficial in summer and drivers should travel at maximum possible speeds

Explanation

High ambient heat and continuous highway rolling cause tire temperatures and internal pressures to rise significantly. Pouring cold water or deflating hot tires causes rapid localized rubber contraction, tread cracking, uneven internal stress, and brake drum warping/cracking. The correct procedure is parking in shade and allowing natural air cooling.

Question 37China Road Framework

When approaching an expressway toll plaza (高速公路收费站), what is the correct civilized and safe driving protocol for a passenger bus?

  1. Decelerate early, observe lane overhead indicators, select the designated ETC or manual passenger toll lane, maintain safe spacing, and refrain from abrupt lane changes across toll approach lines Correct answer.
  2. Maintain 100 km/h until 10 meters before the toll barrier, then brake aggressively
  3. Weave across multiple toll lane queues to find the shortest line, cutting off smaller vehicles
  4. Honk continuously to force passenger cars out of the ETC lane

Explanation

When approaching toll plazas, drivers must reduce speed according to posted reduction signs, observe overhead lane signs, choose the appropriate lane (ETC or manual passenger vehicle lane), maintain generous following distance, and avoid abrupt lateral lane changes across approach channelization markings.

Question 38China Road Framework

When passing through deep roadside puddles in urban or rural areas with pedestrians or cyclists on the sidewalk, what is the driver's civilized duty?

  1. Decelerate significantly before the puddle to avoid splashing muddy water onto pedestrians and non-motorized vehicles Correct answer.
  2. Accelerate to blow the standing water away from the roadway
  3. Honk loudly to command pedestrians to run away from the sidewalk
  4. Drive on the sidewalk to avoid the puddle entirely

Explanation

Civilized driving requires bus drivers to reduce speed when driving through puddles to prevent spraying muddy water and road grime over pedestrians, cyclists, or waiting passengers. Splashing pedestrians is uncivilized and can cause cyclists to lose balance and fall under traffic.

Question 39China Road Framework

When entering or exiting an expressway service area (高速公路服务区), what is the correct lane and speed transition procedure?

  1. Signal in advance, enter the deceleration lane (减速车道) to reduce speed before the service ramp; when exiting, accelerate up to highway speed in the acceleration lane (加速车道) before merging into traffic Correct answer.
  2. Brake to 20 km/h in the leftmost fast lane before cutting sharply across all lanes into the service area
  3. Merge directly from the service area exit ramp into the main travel lane at 20 km/h without using the acceleration lane
  4. Reverse back into the service area if the entrance ramp was missed by 50 meters

Explanation

Expressway service area transitions require proper use of speed-change lanes: drivers must enter the deceleration lane before braking when entering, and utilize the full length of the acceleration lane to match cruising traffic speeds before merging smoothly into the main carriageway.

Question 40Hazards Fitness

Under Article 48 of the Road Traffic Safety Law Implementation Regulations, what lighting rules must a bus driver follow when meeting an oncoming vehicle at night on an unlit road?

  1. Switch from high beams (远光灯) to low beams (近光灯) at least 150 meters away from the oncoming vehicle Correct answer.
  2. Keep high beams on continuously to ensure the bus driver maintains maximum forward visibility
  3. Turn off all headlights and operate solely on parking lights to avoid dazzling the oncoming driver
  4. Switch to emergency hazard flashers and accelerate past the oncoming vehicle

Explanation

Article 48(1) mandates that when meeting oncoming traffic at night on roads without street lighting, drivers must switch from high beams to low beams at a distance of not less than 150 meters from the approaching vehicle. High beams at close range dazzle oncoming drivers, creating temporary blindness and severe collision risks.

Question 41Hazards Fitness

When driving a high-sided passenger bus across a long sea-crossing bridge or through a mountain valley where 'Crosswind' warning signs (横风标志) are posted, what is the proper operational procedure?

  1. Firmly grip the steering wheel with both hands, decelerate smoothly, anticipate lateral aerodynamic deviation, and gently correct steering toward the upwind side without abrupt jerks Correct answer.
  2. Accelerate to maximum speed to cut through the crosswind gust quickly
  3. Slam on the brakes immediately upon feeling the vehicle sway laterally
  4. Steer sharply toward the bridge guardrail to lean against the wind barrier

Explanation

High-sided passenger coaches have large lateral surface areas that make them susceptible to sudden crosswinds on bridges and valley passes. Drivers must firmly grip the steering wheel with both hands, reduce speed to decrease aerodynamic overturning moments, and make gentle, progressive steering corrections against the drift direction. Sharp braking or sudden jerks can induce rollover or loss of directional control.

Question 42Hazards Fitness

During heavy rainfall on an expressway, passenger buses face a heightened risk of 'hydroplaning' (水滑现象). What is the primary cause of hydroplaning and how should the driver prevent it?

  1. Water accumulates between the tire tread and road surface faster than tread grooves can evacuate it, lifting the tire off the pavement; prevented by reducing speed and avoiding worn tires Correct answer.
  2. Rainwater cools the brake discs below zero degrees Celsius, causing them to freeze instantly; prevented by dragging the brakes continuously
  3. Rainwater enters the engine air intake manifold, causing sudden acceleration; prevented by shifting into neutral
  4. Hydroplaning only occurs when tire pressure is three times higher than manufacturer specifications; prevented by deflating tires by half

Explanation

Hydroplaning occurs when water film thickness and vehicle speed prevent tire tread patterns from displacing water, creating a water wedge that lifts tires off the road and results in complete loss of steering and braking traction. The primary preventive measure is reducing vehicle speed significantly on wet surfaces and ensuring adequate tire tread depth.

Question 43Hazards Fitness

According to Article 81 of the Road Traffic Safety Law Implementation Regulations, when driving a passenger bus on an expressway in dense fog with visibility of less than 50 meters, what mandatory actions must be taken?

  1. Turn on fog lights, low beams, clearance lights, and hazard warning flashers; limit speed to no more than 20 km/h; and exit the expressway at the nearest interchange ramp as soon as possible Correct answer.
  2. Turn on high beams and travel at 60 km/h in the leftmost overtaking lane to clear the fog bank quickly
  3. Stop the bus immediately in the central travel lane and wait for the fog to dissipate
  4. Honk continuously and follow the rear bumper of the lead vehicle at a distance of 5 meters

Explanation

Article 81 mandates that when expressway visibility is less than 50 meters, drivers must activate fog lights, low beams, clearance lights, and hazard flashers; maintain a maximum speed of 20 km/h; and exit the expressway via the nearest exit ramp or service area as soon as safely practicable.

Question 44Hazards Fitness

When a passenger coach breaks down on an unlit highway at night, what vehicle lights must be illuminated according to Article 60 of the Road Traffic Safety Law Implementation Regulations?

  1. Hazard warning flashers (危险报警闪光灯), clearance lights / outline marker lights (示廓灯), and rear position tail lights (后位灯) Correct answer.
  2. High-beam headlights and high-power roof searchlights only
  3. Interior passenger cabin dome lights only, with all exterior lights extinguished
  4. Left turn signal only

Explanation

Article 60 requires that during night breakdowns or roadside emergency stops, the vehicle must activate its hazard warning flashers, clearance marker lights (示廓灯), and rear position lights to clearly outline the vehicle's dimensions to approaching traffic from all directions.

Question 45Incident Environment

Under Article 82 of the Road Traffic Safety Law Implementation Regulations, under what circumstances may a commercial passenger bus drive or stop in the expressway emergency lane (应急车道)?

  1. Only when the vehicle suffers an emergency breakdown, tire failure, or passenger medical crisis that makes continued driving impossible Correct answer.
  2. Whenever traffic is congested in the regular travel lanes to keep the bus schedule on time
  3. To allow passengers to disembark for personal biological needs or sightseeing
  4. Whenever the driver needs to inspect mobile phone navigation messages

Explanation

Article 82 strictly forbids motor vehicles from driving or stopping in expressway emergency lanes except in genuine emergencies (mechanical breakdown, severe accident, sudden acute medical crisis). Using emergency lanes to bypass traffic jams incurs severe demerit points (6 points) and heavy fines.

Question 46Incident Environment

When dialing emergency rescue services (110 Police, 120 Medical, 119 Fire, 122 Traffic Accident, 12122 Expressway Rescue) following an expressway crash, what key location information must the driver provide accurately?

  1. Expressway route code/name (e.g., G42), direction of travel, exact kilometer milestone and 100-meter post marker (公里桩与百米桩), vehicle types involved, passenger casualty count, and hazardous conditions Correct answer.
  2. The color of the roadside grass and weather forecast for tomorrow
  3. The driver's personal monthly income and fuel consumption rating
  4. Only state 'come quickly to the highway' and hang up immediately

Explanation

On expressways, emergency dispatchers require precise physical coordinates: the highway designation (e.g., G4 Beijing-Hong Kong-Macau Expressway), travel direction (e.g., northbound toward Wuhan), and the exact numbers from the green roadside kilometer post and small white 100-meter marker (e.g., K1025 + 400m), along with casualty numbers and hazard types.

Under Article 62 of the Regulations on the Implementation of the Road Traffic Safety Law, drivers are strictly prohibited from driving continuously for more than 4 hours without stopping for rest. When stopping for rest, the duration must not be less than 20 minutes.

Question 48Hazards Fitness

Outside of the designated operational hours indicated on a dedicated bus lane sign (e.g., during off-peak midday or late night), how is traffic permitted to use that lane?

  1. The lane is completely closed to all vehicular traffic including buses
  2. Only non-motorized bicycles and electric scooters may use the lane
  3. Only emergency ambulances may enter the lane at any time
  4. Other social motor vehicles are permitted to drive in the lane unless prohibited by other specific road signs Correct answer.

Explanation

When dedicated bus lanes specify active operational time windows (e.g., peak commuting hours), social motor vehicles may lawfully utilize the lane during non-operational off-peak periods, following general lane-use rules.
