GA CDL Passenger key terms

A systematic check of the vehicle's critical parts and systems performed before driving, covering brakes, tires, lights, steering, mirrors, emergency exits, and passenger safety equipment. Defects found must be corrected or reported before the trip begins.

A written record, required after each pre-trip and post-trip inspection, listing any defect that could affect safe operation or cause a breakdown. The driver signs it and the carrier must repair or document the defect.

A sequence of checks on air-braked vehicles verifying that air pressure builds properly, that leaks stay within limits, and that the low-pressure warning and emergency spring brakes activate. It is normally done during the pre-trip inspection.

The lever that links a brake chamber pushrod to the brake shoe, multiplying force to apply the brakes. A loose or misaligned adjuster reduces braking power, so it is checked for travel and alignment during inspection.

Loss of stopping power caused by overheating brakes, common on long downgrades when brakes are used continuously. Drivers control it by selecting a lower gear and using engine braking rather than riding the brakes.

Using the engine's compression resistance, often through a retarder or by downshifting, to slow the vehicle without continuous service braking. It helps prevent brake fade on long or steep descents, especially with a loaded bus.

An emergency escape lane filled with gravel or sand, built on steep downgrades so a driver who loses braking control can steer into it and be stopped by the deep surface.

The safety margin a driver keeps around the vehicle by controlling following distance and avoiding being boxed in. A larger cushion gives more time to react to traffic and to stop smoothly, protecting standing or seated passengers.

A guideline that a passenger vehicle should stay at least one second per ten feet of vehicle length behind the vehicle ahead, plus extra time in rain, darkness, or heavy traffic. It provides room to stop gradually.

Applying the brakes gradually and early so passengers are not thrown forward or sideways. Because riders are often standing or not belted, sudden stops are a leading cause of injuries inside the bus.

Side-to-side rocking of the vehicle caused by abrupt steering, high speed in curves, or uneven loading. It can make standing passengers lose balance, so drivers slow down before curves and turn gradually.

The outward movement of the rear of a long vehicle when the front wheels turn, which can strike pedestrians, poles, or parked vehicles. Drivers check mirrors and allow extra room before turning or pulling away from a curb.

The tendency of the rear wheels of a long vehicle to follow a tighter path than the front wheels in a turn. It can cause the rear to clip curbs or vehicles, so drivers swing wider and check mirrors through the turn.

An area around the vehicle that cannot be seen in the mirrors or directly. Large passenger vehicles have wide blind spots, so drivers adjust mirrors, use convex mirrors, and check carefully before changing lanes.

A requirement that certain passenger vehicles, including school buses and vehicles carrying passengers for hire, stop before crossing railroad tracks unless a traffic control device or enforcement official directs otherwise, then proceed only when safe.

Flashing lights used to warn other drivers that a vehicle is stopped or moving slowly, such as when unloading passengers or pulled to the roadside. Their use signals approaching traffic to slow and pass with care.

Choosing where to stop to load or unload so passengers can reach a curb or safe area without crossing traffic. The stop should be off the travel lane where possible, on level ground, and clear of hazards.

Help given to passengers getting on or off, including operating wheelchair lifts, kneeling the bus, holding doors, or offering an arm. Drivers must secure mobility devices and follow carrier procedures for riders who need extra time.

The process of locking a wheelchair or mobility scooter into place and fastening occupant restraints before the vehicle moves. Proper securement prevents the device from shifting during braking, turning, or a crash.

A passenger who rides while standing, typically holding a stanchion or strap. Standees are at greater risk from sudden stops and sway, so drivers must accelerate, brake, and turn more gently when standees are aboard.

The number of riders aboard, tracked as they board and exit. Accurate counts are essential for safe loading within capacity and for accounting for everyone during an evacuation or emergency.

The maximum number of passengers a vehicle may carry, set by the manufacturer and by seating and standing design. Exceeding it creates unsafe crowding, blocks aisles, and overloads brakes and tires.

The requirement that aisles, doorways, and emergency exits stay free of luggage, strollers, and standing riders so people can move and exit quickly. Blocked exits are a serious safety violation.

A door, window, roof hatch, or other opening designed for rapid escape from the vehicle. Drivers must know how each type operates and ensure exits are unobstructed and marked before every trip.

The organized removal of passengers from a vehicle during a fire, crash, or other danger. The driver directs the process, chooses the safest exits, assists those who need help, and moves everyone to a safe distance.

Steps taken after a crash or breakdown to prevent further harm, such as stopping safely, setting hazard lights, placing reflective triangles, and warning oncoming traffic before helping the injured.

Warning devices placed on the road behind a stopped vehicle to alert approaching drivers. Placement distances depend on road type and speed limit, and they must never be put in a lane of moving traffic.

The skill of aiming a charged extinguisher at the base of a small fire, sweeping side to side, and retreating if it grows. Drivers should know its location and inspect its charge before each trip.

The legal duties after a collision, typically including stopping, protecting the scene, notifying authorities, exchanging information, and rendering reasonable aid within one's training and ability.

Federal limits on driving and on-duty time for commercial passenger carriers, designed to prevent fatigue. They set maximum driving hours, minimum rest breaks, and required off-duty periods between shifts.

The maximum time a driver may operate a commercial passenger vehicle within a duty period and a work cycle. Once reached, the driver must stop driving and take required rest before operating again.

All time from the start of work until release from duty, including driving, loading and unloading passengers, inspecting the vehicle, and waiting to be dispatched. It counts toward daily and cycle limits.

Time when the driver is relieved of all work responsibilities and may rest or sleep. It does not count toward on-duty limits and is required in set amounts between shifts and within the work cycle.

A log documenting a driver's work hours, driving time, and rest periods for each day. It must be accurate, current, and available for inspection, and it supports compliance with hours-of-service rules.

An onboard system that automatically records driving time and duty status, replacing paper logs for most carriers. Drivers must know how to use it, review it, and report malfunctions per regulations.

Practices that reduce drowsy driving risk, such as adequate sleep, planned rest breaks, avoiding driving during natural low-energy hours, and recognizing warning signs like yawning or drifting. Fatigue impairs judgment as much as alcohol.

A directive from an enforcement officer or carrier that a driver or vehicle may not operate until a serious violation or defect is corrected. Operating while out of service carries heavy penalties.
