Question 1S endorsement knowledge test (school bus endorsement)

Under Kansas law, what color flashing lights must a school bus driver activate before stopping to load or unload students on a roadway?

  1. Amber warning lights only
  2. White strobe lights only
  3. Hazard flashers on all four corners
  4. Red flashing lights and the stop arm Correct answer.

Explanation

Kansas requires the red flashing lights and the extended stop arm to be displayed whenever a school bus stops on a roadway to load or unload students. These signals warn traffic in both directions to stop. Amber lights are used only to warn of an approaching stop, not during the stop itself.

Question 2S endorsement knowledge test (school bus endorsement)

Before a school bus driver may transport students, Kansas requires completion of which pre-trip safety check?

  1. A weight check at a highway scale
  2. A tire rotation record signed by a mechanic
  3. A brake dynamometer test at a certified shop
  4. A walk-around inspection of lights, tires, brakes, and emergency equipment Correct answer.

Explanation

The daily pre-trip inspection is a walk-around check of lights, tires, brakes, mirrors, and emergency equipment, and it must be done before transporting students. The driver documents defects and reports them so they are corrected. Mechanical shop tests and scale checks are not the required daily driver duty.

Question 3S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is involved in a crash with injury. Which action is required in addition to stopping and rendering aid?

  1. Wait for the next scheduled dispatcher check-in
  2. Report only if damage exceeds one thousand dollars
  3. Notify the school district and law enforcement immediately Correct answer.
  4. Continue the route and report at the end of the day

Explanation

After a crash involving injury, the driver must stop, render aid, and promptly notify law enforcement and the district transportation office. Delaying notification until the route ends or the next check-in is not acceptable. Prompt reporting allows medical and supervisory response.

Question 4S endorsement knowledge test (school bus endorsement)

What is the proper way for a school bus driver to check that students have cleared the danger zone before moving the bus?

  1. Honk twice and accelerate slowly
  2. Rely on the crossing guard's hand signal
  3. Ask a student near the front to watch the door
  4. Count students on the bus and check mirrors before releasing the brake Correct answer.

Explanation

The driver must account for every student, use all mirrors to verify the danger zone is clear, and only then release the parking brake and proceed. Mirror checks confirm no child is in front of, beside, or behind the bus. Delegating this duty or relying on sound is unsafe.

Question 5S endorsement knowledge test (school bus endorsement)

When a school bus is stopped to unload students, how far from the bus should students be instructed to walk before crossing in front of it?

  1. At least ten feet ahead, within the driver's view Correct answer.
  2. Behind the bus where traffic has already stopped
  3. Directly against the front bumper
  4. Twenty-five feet ahead, out of mirror view

Explanation

Students should move at least ten feet ahead of the bus and wait for the driver's signal before crossing, keeping them visible in the driver's mirrors. Staying close to the bumper places them in a blind spot. Crossing behind the bus exposes them to passing traffic.

Question 6S endorsement knowledge test (school bus endorsement)

What does Kansas law require of traffic approaching a stopped school bus that is displaying red flashing lights on a two-lane road?

  1. Traffic in both directions must stop Correct answer.
  2. Traffic may pass if no children are visible
  3. Traffic may pass at reduced speed
  4. Only traffic behind the bus must stop

Explanation

On an undivided two-lane roadway, vehicles traveling in both directions must stop for a school bus displaying red flashing lights and the stop arm. The stop remains in effect until the lights are turned off. Passing based on the driver's own judgment of children is not allowed.

Question 7S endorsement knowledge test (school bus endorsement)

Which item belongs in the emergency equipment that a Kansas school bus must carry?

  1. A tow chain
  2. A spare alternator belt
  3. A fire extinguisher and a first aid kit Correct answer.
  4. A portable generator

Explanation

School buses must carry emergency equipment including a fire extinguisher, first aid kit, and warning devices such as reflective triangles. These items allow the driver to respond to fire, injury, and roadside hazards. Spare parts and generators are not required emergency equipment.

Question 8S endorsement knowledge test (school bus endorsement)

A school bus driver must activate the amber warning lights at what point before a stop?

  1. Only when students request it
  2. After opening the door
  3. Only after stopping at the curb
  4. Far enough in advance to warn traffic, generally several hundred feet before the stop Correct answer.

Explanation

Amber warning lights are turned on well before the stop, typically several hundred feet ahead, to alert following and oncoming traffic that a stop is coming. The red lights and stop arm follow once the bus is stopped. Activating amber lights after stopping defeats their warning purpose.

Question 9S endorsement knowledge test (school bus endorsement)

A Kansas school bus is stopped on a divided highway with a raised median separating the directions of travel. What must oncoming traffic on the opposite side of the median do?

  1. Proceed without stopping Correct answer.
  2. Stop as on any two-lane road
  3. Stop and wait for a police officer
  4. Stop only if a student is crossing

Explanation

When a raised median or physical barrier separates opposing traffic, vehicles on the opposite side of the median are not required to stop for the school bus. The barrier separates them from the students' path. Traffic on the same side as the bus must still stop.

Question 10S endorsement knowledge test (school bus endorsement)

A student drops a book in the aisle while the bus is moving. What should the driver do?

  1. Stop in the traffic lane and pick it up immediately
  2. Ask a student to retrieve it while the bus moves
  3. Ignore it until the end of the route
  4. Continue to a safe location, stop, and secure the item Correct answer.

Explanation

The driver should not stop in a live traffic lane for a dropped item or leave the seat while moving. The safe practice is to continue to a safe stopping point, then secure the object. Having students move in a moving bus creates a fall hazard.

Question 11S endorsement knowledge test (school bus endorsement)

During a bus evacuation drill, which exit should the driver describe first for students seated in the rear of the bus?

  1. The rear emergency door Correct answer.
  2. The roof hatch
  3. The driver's side window
  4. The front service door only

Explanation

Students seated in the rear are closest to the rear emergency door, so that exit is typically assigned first for them. Evacuation planning assigns exits based on seating to speed orderly egress. The front door is assigned to students seated near the front.

Question 12S endorsement knowledge test (school bus endorsement)

How should a school bus driver adjust the convex mirrors before starting a route?

  1. So the side of the bus fills most of the mirror
  2. So the driver's own face is centered
  3. So the rear wheels are the only visible object
  4. So the driver can see the danger zone along the side and front of the bus Correct answer.

Explanation

Convex mirrors are positioned to show the danger zone beside and in front of the bus, including the area near the front door and wheels. They are not meant to show the bus body or the driver. Proper adjustment lets the driver see students near the bus.

Question 13S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver's CDL with the S endorsement is subject to which additional requirement?

  1. Periodic physical examinations and a current medical examiner's certificate Correct answer.
  2. A commercial driver's license from another state
  3. A special school bus-only license plate
  4. An annual background check by the state patrol

Explanation

Drivers holding a CDL, including the school bus S endorsement, must meet physical qualification standards and keep a current medical examiner's certificate. The certificate documents fitness to drive. Background checks and licensing are handled through separate processes.

Question 14S endorsement knowledge test (school bus endorsement)

What is the correct procedure when a school bus must stop on railroad tracks because of traffic ahead?

  1. Stop on the tracks and set the parking brake
  2. Sound the horn and cross slowly
  3. Stop on the tracks and wait for the light to change
  4. Never stop on the tracks; stop before them and wait until there is room to clear completely Correct answer.

Explanation

A school bus must never occupy railroad tracks while waiting in traffic. The driver should stop before the tracks and proceed only when there is enough space to clear them completely. Stopping on the tracks risks a catastrophic collision with a train.

Question 15S endorsement knowledge test (school bus endorsement)

Before crossing railroad tracks, a school bus driver should do which of the following?

  1. Turn off the engine to hear better
  2. Open the door and window to listen, and check both directions Correct answer.
  3. Rely on the crossing gate alone
  4. Honk and proceed without stopping

Explanation

At a railroad crossing, the driver should stop, open the door and window to listen, and look both ways before proceeding. This allows the driver to hear an approaching train that may not be visible. Relying only on gates or signals is insufficient because they can malfunction.

Question 16S endorsement knowledge test (school bus endorsement)

A school bus driver is caught in a severe thunderstorm with reduced visibility. What is the safest action?

  1. Follow the vehicle ahead closely for guidance
  2. Pull off the road in a safe location and wait for conditions to improve Correct answer.
  3. Turn on hazard lights and continue at normal speed
  4. Maintain speed to clear the area quickly

Explanation

When visibility is severely reduced, the safest choice is to pull off in a safe location and wait for conditions to improve. Continuing at speed or following closely increases crash risk. The driver should notify dispatch of the delay.

Question 17S endorsement knowledge test (school bus endorsement)

What is the primary purpose of the school bus danger zone?

  1. The lane reserved for buses during school hours
  2. The area where students may store backpacks
  3. The area around the bus where the driver's visibility is limited and students are at risk Correct answer.
  4. The area behind the bus used for loading wheelchairs

Explanation

The danger zone is the area immediately around the bus where the driver's view is restricted and students are most at risk of being struck. Drivers and students must treat this area with caution during loading and unloading. It is not a storage or travel lane.

Question 18S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is transporting students with disabilities. Which practice best supports their safe transport?

  1. Load all students through the rear door
  2. Allow students to ride standing if the trip is short
  3. Skip the pre-trip inspection to save time
  4. Secure wheelchairs and use the equipment specified for each student Correct answer.

Explanation

Students using wheelchairs must be secured with the proper tie-downs and restraint systems specified for their equipment. Loading should follow the assigned procedure, and the pre-trip inspection is still required. Students must remain secured while the bus is moving.

Question 19S endorsement knowledge test (school bus endorsement)

What should a school bus driver do if a student refuses to remain seated while the bus is moving?

  1. Speed up to reach school sooner
  2. Stop in the traffic lane and order the student off
  3. Continue driving and ignore the behavior
  4. Pull over safely and address the situation before proceeding Correct answer.

Explanation

The driver should pull over at a safe location and address the behavior before continuing. Stopping in a traffic lane is unsafe, and ignoring the behavior leaves other students at risk. The incident should also be reported according to district policy.

Question 20S endorsement knowledge test (school bus endorsement)

Under Kansas law, when may a school bus driver permit a student to leave the bus at a stop other than the assigned one?

  1. Whenever the student asks
  2. Never under any circumstance
  3. Only if the student is in a hurry
  4. Only with proper authorization from a parent or school official Correct answer.

Explanation

Students should be released only at their assigned stop unless a parent or school official has authorized a change. This protects students from being dropped where no one is expecting them. The driver documents or confirms the authorization per district policy.

Question 21S endorsement knowledge test (school bus endorsement)

A school bus driver is backing the bus in a school lot. Which practice is correct?

  1. Back quickly to minimize time in the lot
  2. Use a spotter and back only when necessary, checking mirrors and the rear area Correct answer.
  3. Back using mirrors only, without assistance
  4. Sound the horn and back without looking

Explanation

Backing should be avoided whenever possible; when it is necessary, the driver uses a spotter and checks mirrors and the area behind the bus. A spotter helps confirm the path is clear. Backing without assistance or at speed creates a serious risk to pedestrians.

Question 22S endorsement knowledge test (school bus endorsement)

A school bus driver's route requires a left turn across traffic at an intersection with a protected arrow. What is the safest approach?

  1. Wait for a police officer to direct the turn
  2. Turn from the right lane to save time
  3. Turn immediately when the light turns green, regardless of the arrow
  4. Turn on the green arrow only after confirming the path is clear of pedestrians and vehicles Correct answer.

Explanation

Even with a protected green arrow, the driver must confirm the intersection and crosswalk are clear before turning. Pedestrians or vehicles may still be in the path. Turning from the wrong lane or without checking creates a collision risk.

Question 23S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver notices the stop arm fails to extend at a student stop. What is the correct action?

  1. Unload students and report the defect at the end of the week
  2. Proceed with unloading while waving traffic around
  3. Use hand signals instead of the stop arm
  4. Do not unload students until the stop arm is functioning or an alternate safe procedure is followed Correct answer.

Explanation

A malfunctioning stop arm means the required warning signal is not displayed, so students should not be unloaded until the problem is corrected or an approved safe procedure is used. The defect must be reported promptly. Proceeding without the signal endangers students.

Question 24S endorsement knowledge test (school bus endorsement)

A school bus is stopped to load students when a vehicle passes the bus on the left despite the red lights. What should the driver do first?

  1. Ignore the violation and continue loading
  2. Chase the vehicle to obtain its plate number
  3. Sound the horn continuously and pull into traffic
  4. Keep students on the bus or curb and record details for reporting Correct answer.

Explanation

The driver's first duty is to keep students safe by holding them on the bus or curb until the roadway is clear. The driver should record details such as the plate number and description for reporting. Chasing the vehicle or pulling into traffic endangers students.

Question 25S endorsement knowledge test (school bus endorsement)

During a fire on a school bus, which evacuation approach is most appropriate?

  1. Evacuate through the exit nearest the fire for speed
  2. Open all windows and continue the route
  3. Keep students seated until the fire department arrives
  4. Evacuate students through the exit farthest from the fire and move them well away from the bus Correct answer.

Explanation

Students should be evacuated through an exit away from the fire and moved a safe distance from the bus. Keeping them aboard or routing them past the fire exposes them to smoke and flames. The driver then accounts for all students and calls for help.

Question 26S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is preparing to make a stop where students will cross the roadway. Which mirror system is designed specifically to let the driver see the area directly in front of and along the sides of the bus near the front bumper?

  1. The interior overhead mirror
  2. The flat left-side mirror
  3. The convex crossover mirrors mounted on the front fenders Correct answer.
  4. The right-side flat mirror

Explanation

Crossover (convex) mirrors mounted at the front corners are aimed to show the danger zone immediately in front of the bus and along both sides near the front wheels, letting the driver see students who have stepped off and are crossing. Flat side mirrors show the sides and rear lanes, and the interior mirror is for monitoring the passenger area.

Question 27S endorsement knowledge test (school bus endorsement)

While loading students at a stop, a Kansas school bus driver should count students and account for them in which way before moving the bus?

  1. Sound the horn once and pull away slowly
  2. Wait a fixed 30 seconds then proceed regardless
  3. Rely on the students to signal when everyone is aboard
  4. Confirm each student is seated or clear of the danger zone and the count matches Correct answer.

Explanation

The driver must account for every student before moving: verify that each one is either seated or safely clear of the bus, and that the number of students matches the expected count. This prevents leaving a child in the danger zone. Fixed time delays or horn signals do not confirm a child's location.

Question 28S endorsement knowledge test (school bus endorsement)

Under Kansas requirements, a school bus driver must ensure students are evacuated how quickly during a drill when conditions permit?

  1. Within 5 minutes
  2. No time standard applies to drills
  3. Within about 60 seconds for a well-practiced evacuation Correct answer.
  4. Within 10 minutes

Explanation

Kansas evacuation drills are timed, and a well-executed evacuation of a loaded bus is expected to be completed in roughly one minute or less. This standard reflects the need to clear the bus rapidly in a real emergency. Longer intervals do not meet the drill performance expectation.

Question 29S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is supervising students during an evacuation drill. Which command best keeps students safe once they have exited the bus?

  1. Move the students a safe distance from the bus and keep them together in a group Correct answer.
  2. Let students return to the bus to collect belongings
  3. Have students stand beside the bus doors to wait
  4. Send students across the road to the far shoulder

Explanation

After exiting, students should be moved well away from the bus and assembled in a controlled group where they can be counted and supervised. Keeping them near the doors or letting them re-enter puts them in the danger zone or back into the hazard.

Question 30S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver has just completed a route and is doing the post-trip inspection. What is the most important check before leaving the bus?

  1. Walk the aisle and check every seat for sleeping or left-behind students Correct answer.
  2. Confirm the radio is turned off
  3. Record the odometer reading for the log
  4. Check only that the fuel gauge reads above half

Explanation

The post-trip walk-through is a child-safety check: the driver must look into every seat, including the back rows, to ensure no student remains aboard. Fuel, radio, and odometer tasks are routine but do not protect against a child being left on the bus.

Question 31S endorsement knowledge test (school bus endorsement)

A Kansas school bus must be equipped with a fire extinguisher rated for which class of fires most likely to occur on a bus?

  1. Class A and B fires, such as burning upholstery and fuel Correct answer.
  2. Class D fires only, such as burning metal
  3. No rating is required as long as one extinguisher is present
  4. Class K fires only, such as cooking oil

Explanation

Bus fire extinguishers are rated for Class A (ordinary combustibles like seats and flooring) and Class B (flammable liquids such as fuel). These cover the most probable fire types on a school bus. Cooking-oil and combustible-metal ratings apply to other settings.

Question 32S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is approaching a stop and sees students waiting close to the edge of the roadway. What is the safest positioning of the bus?

  1. Stop in the traffic lane and wave students across
  2. Stop so students must walk to the bus rather than the bus pulling toward them Correct answer.
  3. Pull as close to the students as possible to shorten their walk
  4. Stop several car lengths past the group and back up

Explanation

The driver should stop in a position that requires students to come to the bus, keeping the bus from crowding them against the curb or shoulder. Backing up near students is prohibited, and stopping in a travel lane creates a collision hazard.

Question 33S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is driving a route and a student begins to choke on food. What should the driver do first?

  1. Open the emergency exit and evacuate all students immediately
  2. Speed up to reach the school nurse as quickly as possible
  3. Continue driving to the next stop while asking other students to help
  4. Stop the bus in a safe location and provide aid while sending for help Correct answer.

Explanation

The driver's first duty is to stop safely and render appropriate aid, such as first aid or the Heimlich maneuver, while arranging for emergency help. Continuing to drive or speeding endangers everyone aboard and delays care. A full evacuation is not warranted by a single choking student.

Question 34S endorsement knowledge test (school bus endorsement)

Kansas requires school bus drivers to be tested for alcohol and controlled substances under which circumstances?

  1. Pre-employment, post-accident when required, random, reasonable suspicion, return-to-duty, and follow-up Correct answer.
  2. Only after a crash involving injury
  3. Only at the time of the initial CDL skills test
  4. Only when a supervisor requests it

Explanation

School bus drivers fall under federal and state drug and alcohol testing rules that include pre-employment, random, reasonable-suspicion, post-accident, return-to-duty, and follow-up testing. Testing is not limited to crashes or supervisor discretion.

Question 35S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is inspecting the bus before a route and finds the service door does not latch securely. What should the driver do?

  1. Continue the route and report it at the end of the day
  2. Tape the door shut and run the route
  3. Have a student hold the door closed during the route
  4. Remove the bus from service and report the defect before carrying students Correct answer.

Explanation

A defective service door is a safety defect that must be corrected before the bus carries passengers. The driver should place the bus out of service and report the problem so it is repaired. Improvised fixes or student assistance are unacceptable.

Question 36S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is stopped to unload students and must cross the street to reach the sidewalk. Which signal should the driver give the students to cross?

  1. A hand signal indicating it is safe to cross Correct answer.
  2. A single blast of the horn
  3. Flashing the headlights
  4. Waving from inside the bus without checking traffic

Explanation

When students must cross the roadway, the driver stays in place and uses an established hand signal to tell them when it is safe, after checking traffic in both directions. Horn blasts and headlight flashes are not the standard crossing signal and can confuse other motorists.

Question 37S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is operating a bus equipped with a crossing gate (stop arm) and red lights. When should the red lights and stop arm be activated?

  1. At every intersection regardless of students
  2. Only when another vehicle is approaching from behind
  3. When the bus is stopped to load or unload students who must cross the roadway Correct answer.
  4. Whenever the bus slows for any turn

Explanation

The red flashing lights and stop arm are used when the bus is stopped to load or unload students, particularly when students must cross the road. They are not used for ordinary turns or at every intersection. Activating them only for approaching traffic misuses the warning system.

Question 38S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is driving at night on a rural route and meets an oncoming vehicle with bright headlights. What should the driver do?

  1. Close one eye to preserve night vision
  2. Look toward the right edge of the roadway and reduce speed as needed Correct answer.
  3. Stare directly at the oncoming headlights to judge distance
  4. Turn on the high beams to warn the other driver

Explanation

When glare from oncoming headlights impairs vision, the driver should look toward the right edge of the lane to stay oriented and slow down if visibility is reduced. Staring at the lights worsens glare, and retaliating with high beams increases the hazard for both drivers.

Question 39S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is transporting students and notices smoke coming from under the hood. What is the best first action?

  1. Continue at reduced speed while radioing for instructions
  2. Keep driving to reach the school so students are not stranded
  3. Stop the bus in a safe place, shut off the engine, and evacuate students away from the bus Correct answer.
  4. Open the hood fully to inspect the source of the smoke

Explanation

Smoke from the engine compartment signals a possible fire, so the driver should stop safely, shut down the engine, and evacuate students to a location away from the bus. Continuing to drive or delaying evacuation risks a full fire. Opening the hood fully can feed oxygen to a fire.

Question 40S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is stopped at a railroad crossing and the bus stalls on the tracks. What should the driver do first?

  1. Set the parking brake and wait for help to arrive
  2. Evacuate students away from the tracks and then notify authorities Correct answer.
  3. Call the school dispatcher before doing anything else
  4. Try repeatedly to restart the engine while students remain aboard

Explanation

If a bus stalls on the tracks, the immediate priority is to get students off the bus and well clear of the tracks, then notify authorities. Attempting restarts or making calls while students remain aboard leaves them in extreme danger.

Question 41S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is being passed illegally by a motorist while students are loading. What should the driver do?

  1. Step into the roadway and wave the vehicle down
  2. Chase the vehicle to obtain the license plate
  3. Keep students in a safe position and record the vehicle's identifying information if it is safe to do so Correct answer.
  4. Sound a long horn blast and continue loading immediately

Explanation

The driver's priority is student safety: keep students clear of the roadway and, if it can be done safely, note the vehicle's description and plate for reporting. Chasing the vehicle or stepping into traffic endangers the driver and students.

Question 42S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is checking the bus before a route and the brake warning light stays on after the engine starts. What should the driver do?

  1. Release the parking brake and ignore the light
  2. Keep the bus out of service until the brake system is checked Correct answer.
  3. Pump the brakes while driving to clear the light
  4. Drive the route and monitor the light

Explanation

A brake warning light that stays on indicates a possible brake system fault, and the bus must not be used to transport students until it is inspected and repaired. Driving with a known brake defect risks a catastrophic failure.

Question 43S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is asked to transport a student who uses a wheelchair. What must the driver confirm before departure?

  1. The wheelchair brakes alone are sufficient to hold it in place
  2. The student can transfer to a regular seat without assistance
  3. The student's parent will ride along to secure the chair
  4. The wheelchair is secured and the student is restrained with the appropriate belt system Correct answer.

Explanation

When transporting a wheelchair user, the driver must ensure the wheelchair is properly secured to the floor and the student is restrained with the appropriate occupant belt system. Wheelchair brakes alone do not secure the chair in a moving bus, and not every student can transfer to a seat.

Question 44S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is following another vehicle too closely on a wet road. What following-distance practice is recommended for a loaded school bus?

  1. Keep one bus length behind at all speeds
  2. Maintain a two-second gap regardless of speed or weather
  3. Allow at least one second for each 10 feet of bus length plus additional space for conditions Correct answer.
  4. Follow at the same distance as a passenger car

Explanation

A common guideline for large vehicles is to allow about one second of following distance for each 10 feet of vehicle length, then add more space for wet roads, heavy loads, or higher speeds. A loaded bus needs longer stopping distance than a passenger car.

Question 45S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is preparing to leave a school loading zone crowded with students and parents. What is the safest practice?

  1. Use a spotter and proceed only when the path is clear Correct answer.
  2. Rely on the backup camera alone
  3. Sound the horn and move immediately
  4. Have students guide the bus out of the zone

Explanation

In a crowded loading zone, the driver should use a spotter and move only when the path is confirmed clear, supplementing the mirrors and camera with direct observation. Cameras have blind spots, and horn warnings do not guarantee that people have moved. Students should never direct bus movement.

Question 46S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is driving on a highway and a tire blows out. What should the driver do?

  1. Hold the steering wheel firmly, slow gradually, and pull off the road Correct answer.
  2. Turn sharply onto the shoulder to get off the road quickly
  3. Brake hard immediately to stop as fast as possible
  4. Accelerate to stabilize the bus before slowing

Explanation

With a blowout, the driver should grip the wheel firmly, keep the bus straight, ease off the accelerator, and slow gradually before pulling off the roadway. Hard braking or sharp steering can cause a loss of control or rollover.

Question 47S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is supervising a student who repeatedly violates bus conduct rules. What is the appropriate progression?

  1. Address the behavior, document it, and follow the district's discipline referral process Correct answer.
  2. Ignore minor violations until a major incident occurs
  3. Remove the student from the bus permanently without notice
  4. Assign the student to sit in the driver's seat area indefinitely

Explanation

The driver should correct the behavior, document the incident, and follow the district's established referral and discipline process. Removing a student permanently without notice or ignoring violations is not appropriate, and seating changes are a limited tool rather than a punishment.

Question 48S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is stopped at a red light with students aboard when another vehicle rear-ends the bus. What should the driver do first?

  1. Drive away to avoid blocking traffic
  2. Continue the route if the bus still moves
  3. Check for injuries, secure the scene, and account for all students Correct answer.
  4. Get out to inspect the other vehicle before checking students

Explanation

After a collision, the driver's first duties are to check for injuries, secure the scene, and confirm that every student is accounted for and safe. Leaving the scene, inspecting the other vehicle first, or continuing the route ignores the welfare of passengers.

Question 49S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is approaching a blind curve on a narrow rural road. Which speed and lane practice is safest?

  1. Use the horn continuously through the curve
  2. Slow down and keep well to the right, staying alert for oncoming traffic Correct answer.
  3. Speed up to clear the curve quickly
  4. Maintain the posted speed and stay near the center line

Explanation

On a blind curve, the driver should reduce speed and keep to the right to allow room for oncoming vehicles that may drift over the center line. Maintaining speed near the center line or accelerating through the curve reduces reaction time and margin for error.

Question 50S endorsement knowledge test (school bus endorsement)

A Kansas school bus driver is completing a route and a student reports feeling ill. What is the appropriate action?

  1. Continue the route without reporting the illness
  2. Tell the student to walk home to avoid delay
  3. Keep the student comfortable and supervised and notify the school or parents per policy Correct answer.
  4. Put the student off the bus at the next stop

Explanation

When a student becomes ill, the driver should keep the student supervised and comfortable and notify the school or parents according to district policy. Leaving an ill student at a stop or sending them home alone is unsafe, and failing to report the illness neglects the student's welfare.
