Review all 64 questions with answers

  1. For a new CDL school-bus endorsement, what must an applicant do in addition to the school-bus knowledge test?

    Correct answer: Qualify for P and pass the required school-bus driving test.

    For the CDL school-bus endorsement, federal rules require passenger-endorsement qualification and a skills test in a school bus of the appropriate vehicle group. Passing S knowledge alone is not enough; training and other licensing requirements still apply.

  2. A child disappears beside your stopped bus. Which area needs attention?

    Correct answer: The danger zones around every side of the bus.

    Children can be hidden close to the front, sides or rear. The left side also exposes them to passing traffic; a single mirror view is not a complete check.

  3. You take over a school bus from a taller driver. What should happen before you operate it?

    Correct answer: Check and adjust each mirror for your own seated view.

    Mirror coverage depends on the driver's position. Check all mirrors before operation and have any inadequate view corrected.

  4. What should properly adjusted outside flat mirrors show on a school bus?

    Correct answer: Bus sides, rear tires at ground level and traffic behind.

    Flat mirrors help monitor side clearances and rear traffic. They do not remove the close-in blind spots in front of or behind the bus.

  5. A vehicle looks small in a school bus's convex mirror. What must the driver remember?

    Correct answer: Its apparent size and distance can be distorted.

    Convex mirrors widen the viewing area but distort apparent size and distance. Use them together with the other mirrors and direct observation.

  6. During a mirror check, which view belongs in the outside convex mirrors?

    Correct answer: The bus sides and at least one adjacent lane on each side.

    The handbook calls for side coverage up to the mirror mounts, the front of the rear tires touching the ground, and an adjacent lane on each side.

  7. Which mirror system helps reveal a child directly in front of the bus below normal direct sight?

    Correct answer: The outside crossover mirrors.

    Crossover mirrors cover the front bumper danger zone and areas near the front wheels and service door. They supplement direct vision rather than replacing the other mirrors.

  8. How should crossover-mirror coverage meet the area you can see directly ahead?

    Correct answer: The mirror view and direct view should overlap.

    Overlapping views help avoid an unseen gap in the front danger zone. Proper adjustment includes the front bumper area at ground level and the front tires.

  9. Can the overhead inside mirror replace exterior checks before you leave a student stop?

    Correct answer: No; it primarily monitors the passenger compartment.

    The interior mirror is mainly for observing students. Its limited rear view and blind spots do not replace the exterior mirror checks for traffic and children.

  10. A parent asks you to move tomorrow's bus stop to another driveway. What should you do?

    Correct answer: Obtain written approval from the appropriate school-district official first.

    The manual calls for written approval from the appropriate school-district official before changing a bus stop. A parent's request does not authorize the driver to change the approved route or stop.

  11. As you slow for a student stop, when should you check for children and traffic?

    Correct answer: Before, during and after bringing the bus to a stop.

    Approach cautiously while repeatedly scanning pedestrians, traffic and the mirrors. A situation can change while the bus is slowing or stopped.

  12. Your South Carolina school bus has activated its amber signals while preparing for a pupil stop. What does state law prohibit a motorist behind the bus from doing?

    Correct answer: Overtaking the school bus while its amber signals are actuated.

    South Carolina separately prohibits overtaking a school bus while its amber signals are actuated. This is distinct from the red-light stopping rule and its opposite-direction multi-lane exception.

  13. Under the South Carolina CDL manual's approach procedure, where should the front bumper stop relative to students waiting at a designated bus stop?

    Correct answer: At least 10 feet away from the waiting students.

    The manual specifies a full stop with the front bumper at least 10 feet from waiting students. Having them approach the stopped bus improves the driver's view of their movements; do not roll toward children to close that gap.

  14. Under the South Carolina CDL manual, how should the bus be secured at a pupil stop before boarding?

    Correct answer: Stop fully, select Park or Neutral if no Park position, and set the parking brake.

    The pupil-stop procedure combines a complete stop, Park (or Neutral where there is no Park shift point), and the parking brake. Warning lights do not physically secure the bus.

  15. The red loading lights are flashing. What must you confirm before fully opening the door and signaling children to approach?

    Correct answer: Traffic has actually stopped.

    Warning lamps and the stop arm do not physically stop a motorist. Make the final traffic check before inviting children toward the bus.

  16. At the designated school unloading area, how should students leave once the bus is stopped and secure?

    Correct answer: In an orderly manner after the driver tells them to exit.

    Wait for the stopped, secure bus and the driver's instruction. Orderly movement lets the driver observe students leaving and moving clear.

  17. At the school's loading area, you saw six children but counted five boarding. What is the correct response?

    Correct answer: Account for the missing child before moving.

    Count students and know where each one is. Ask about a missing child and, if necessary, secure the bus and physically check around and underneath before moving.

  18. Everyone you first saw at the stop is seated. Why check the mirrors again before departure?

    Correct answer: A late-arriving child may now be approaching the bus.

    Children may run toward a bus after the original group boards. Make the final exterior checks before returning safely to traffic.

  19. Students have boarded the school bus. According to the South Carolina CDL manual, what must the driver verify before beginning to move?

    Correct answer: That students are seated and facing forward, with everyone accounted for.

    The loading procedure calls for students to be seated and facing forward and for all students to be accounted for. Recheck mirrors for late arrivals before preparing to leave safely.

  20. At a designated school drop-off area, when should students leave their seats?

    Correct answer: After the driver tells them to unload.

    Students stay seated until the driver releases them to unload. The driver counts them off and verifies that each has moved to a safe, visible position.

  21. A student drops a notebook close to a bus wheel. What should the student do?

    Correct answer: Leave it and get the driver's attention from a safe place.

    Teach students not to retrieve objects near or under the bus. They should move to safety and alert the driver so the situation can be handled with the bus secured.

  22. Why watch a student's clothing and backpack while the student steps off?

    Correct answer: They can catch on the handrail or door area.

    Loose straps or clothing can snag during exit. Watch each student clear the doorway and reach a safe location before departure.

  23. On a route where crossing in front is permitted, where should an unloading student wait before the driver signals the crossing?

    Correct answer: At the right road edge, at least 10 feet ahead of the right bumper corner, visible to the driver.

    The manual places the student at least 10 feet ahead of the right bumper corner, away from the bus and at the right edge of the roadway where the driver can see the student's feet. Wait for the driver's signal; South Carolina does not permit routes that require students to cross a multi-lane road.

  24. After a driver signals a student to cross safely in front of a school bus, what must the student do at the bus's left edge?

    Correct answer: Stop, look for the driver's next signal, and check traffic before continuing.

    The handbook adds another pause at the left edge of the bus, followed by the driver's signal and checks in both directions. The student keeps looking while crossing; an initial signal is not a guarantee that traffic has stopped.

  26. You pass a school pickup point but can return by an authorized forward route. Should you reverse toward the waiting pupils?

    Correct answer: No; use the safe authorized forward route.

    The school-bus manual discourages backing and says not to back while students are outside the bus. Use a safe authorized forward route rather than reverse toward waiting children.

  27. A South Carolina school bus is in a designated school loading area entirely off the roadway. Should the driver actuate the special red and amber pupil-stop signals there?

    Correct answer: No; state law prohibits actuating them in that designated entirely off-road area.

    The statute distinguishes designated school loading/off-loading areas entirely off the roadway from roadside stops. The driver must not actuate the special visual signals there, but still must supervise students and check the surrounding area.

    Source: South Carolina Code of Laws, Section 56-5-2770(D)(1); current official posted text reviewed September 21, 2026. ↗

  28. For an ordinary pupil stop on a South Carolina highway, when must the bus's special red and amber visual signals be actuated as applicable?

    Correct answer: When stopped or preparing to stop to receive or discharge school children.

    South Carolina ties these signals to receiving or discharging school children on the roadway. Ordinary parking, fuel stops and personal stops do not become pupil stops.

  29. At the school unloading area, you must leave the driver's compartment to supervise students. How should you secure the bus?

    Correct answer: Stop the engine, set the parking brake and take the ignition key.

    Keep the bus secured with the parking brake and proper transmission position. The school-unloading procedure requires shutting off the ignition and taking the key when leaving the driver's compartment.

  30. A South Carolina school bus is empty as it approaches a railroad grade crossing. Does the school-bus railroad statute limit its stop requirement to trips with pupils aboard?

    Correct answer: No; it requires the operator of any school bus to make the stop.

    The school-bus provision applies to the operator of any school bus and does not condition the required stop on having pupils aboard. It requires the complete stop and a safe-crossing check.

    Source: South Carolina Code of Laws, Section 59-67-230; current official posted text reviewed September 21, 2026. ↗

  31. At a South Carolina school-bus railroad crossing, how far must the bus stop from the rail nearest its front?

    Correct answer: Between 15 and 50 feet away.

    The school-bus statute requires a full stop at least 15 feet and no more than 50 feet from the nearest rail. After stopping, the operator must establish that it is safe to cross.

  33. At the required rail stop, how should you prepare to look and listen?

    Correct answer: Quiet the students and equipment, then open the door and driver window.

    At the railroad stop, open the driver's window and service door to look and listen both ways. Quieting passengers and equipment helps the driver hear approaching rail traffic.

  34. Your school bus approaches a passive railroad crossing without flashing lights or gates. What does the absence of active warning equipment mean?

    Correct answer: The driver must stop, observe carefully and decide whether it is safe to cross.

    At a passive crossing there is no active warning system to make the decision for the driver. Recognize the crossing, make the required stop, check for rail traffic and ensure there is enough room to clear the tracks.

  36. Your school bus is stopped before a crossing with several tracks. When no train is approaching and the exit space is clear, what crossing sequence does the South Carolina manual recommend?

    Correct answer: Proceed across all tracks without an intermediate stop or gear change.

    The manual directs a stop before the first set of tracks, followed by a continuous crossing of all tracks when safe. Choose the gear and confirm the exit space before entering; do not use the gap between tracks as a waiting area.

    Fire or a serious threat of fire requires evacuation. Protect passengers and obtain emergency help; a practice question is not training to fight a bus fire.

  42. The normal entrance is unsafe to use during an evacuation. What should guide your choice of another exit?

    Correct answer: The hazard location and the safest usable exit.

    Choose the front, rear, both, side, window or roof exits according to the emergency and their usability. Do not direct students through the hazard merely to use the usual entrance.

  43. If time and conditions permit, how should you secure the bus before directing an emergency evacuation?

    Correct answer: Set the brake, use Park (Neutral if no Park), stop the engine and take the key.

    For evacuation, secure the bus with the parking brake and Park, or Neutral if there is no Park position. Stop the engine and take the key so an unattended bus cannot be set in motion.

  44. Why teach emergency-exit procedures to all students, even when trained student helpers are assigned?

    Correct answer: The assigned helpers may be absent when an emergency occurs.

    Assigned helpers are useful, but every student needs basic evacuation knowledge. Planning must account for an emergency on a day when those helpers are not riding.

  45. Once students have reached the evacuation meeting place, what must the driver establish?

    Correct answer: That all students are accounted for and any injuries are identified.

    Keep students together at the safe meeting location, account for everyone and check their condition. Communicate with dispatch and responders rather than allowing students to wander back.

  46. A train is approaching a bus trapped on the rails. In which direction should evacuees move?

    Correct answer: Away from the tracks, angled toward the approaching train.

    Move well away from both the bus and the tracks. Angling toward the approaching train takes evacuees away from the direction debris may be carried after impact.

  47. During the South Carolina school year, a bus driver notices a hazardous road condition on the assigned route. What reporting duty applies?

    Correct answer: Report it in writing to the proper school official.

    South Carolina requires drivers to report hazardous route conditions in writing to the proper school official. The official then forwards the report through the transportation-supervisor process; the driver should not simply wait for the annual inspection.

  48. When possible, how does the school-bus handbook suggest assigning students to help during an evacuation?

    Correct answer: Assign two responsible older students at each exit and teach their duties.

    Preassigned, trained helpers can guide students to safety and help at the exits. The manual recommends two responsible older students at each exit when possible, while still teaching the procedure to every student.

  49. A proposed South Carolina school-bus stop would require a student to cross a four-lane road with two lanes in each direction. What must the route design ensure?

    Correct answer: That the student does not have to cross that multi-lane road.

    South Carolina requires multi-lane-route loading and unloading to be designed so students do not cross that roadway. The definition includes four or more traffic lanes with at least two in each direction; it is not limited to roads divided by a median.

  50. Two students argue inside while other children are still unloading. What should your attention remain on first?

    Correct answer: The children and traffic outside until unloading is safe.

    Loading and unloading demand exterior observation. Once students are safely away, handle the behavior issue in a safely stopped and secured bus according to local procedures.

  51. A passenger's behavior prevents you from safely driving the school bus. What should you do?

    Correct answer: Stop and secure the bus safely, then request authorized assistance.

    Use a safe stopping location and follow the school's assistance and discipline procedures. Do not put a student out at an unauthorized location.

  52. In an emergency stop with working ABS on your school bus, what should you avoid?

    Correct answer: Pumping the brake pedal.

    Do not pump the brakes of an ABS-equipped bus in an emergency. Apply the braking force needed to stop safely while maintaining control.

  53. What does ABS fail to protect a school bus from?

    Correct answer: A skid caused by taking a turn too fast.

    ABS helps with brake-induced wheel lock. It does not make excessive cornering speed, close following or poorly maintained brakes safe, and it does not guarantee a shorter stop.

  54. Strong crosswinds begin pushing your school bus sideways. What is the appropriate response?

    Correct answer: Reduce speed and, if necessary, stop safely and contact dispatch.

    The large side area makes the bus vulnerable to wind. Maintain a firm grip, anticipate gusts, slow down and wait in a safe place if conditions require it.

  55. As you turn away from a curb, why check the school bus's rear overhang in the mirrors?

    Correct answer: Its tail can swing outward toward nearby people or objects.

    A long rear overhang can sweep outward during a turn. Check before and during the movement; do not treat a handbook example as an exact clearance for every bus.

  56. According to the South Carolina school-bus manual, may you back the bus while students are outside it?

    Correct answer: No; do not back while students are outside the bus.

    The manual strongly discourages backing and says not to back while students are outside. If there is no safe forward option, use the required safe procedure and have students inside before backing.

  57. Your authorized pickup requires unavoidable backing. In what order should you handle students?

    Correct answer: Board them before backing, then watch for late arrivals.

    For a necessary backing point, board pupils before backing and unload them after backing. Do not leave pupils outside to guide or wait beside the maneuver.

  58. What baseline physical-examination schedule does South Carolina law set for school-bus drivers?

    Correct answer: Before testing and at least every two years afterward.

    The statute requires a certified examination meeting the specified federal and state requirements before testing and at least every two years afterward. A school district may require additional examinations; this is not a promise that every medical certificate is valid for two full years.

  59. The route has ended and the bus seems quiet. What must the driver still do?

    Correct answer: Walk through and check for sleeping or hiding students.

    A physical post-trip check can find a student who is asleep or hidden from the driving position. Also check belongings, exits and visible problems and make required reports.

  60. A driver has the appropriate CDL endorsements and plans to drive a school bus taking South Carolina pupils to or from school. What does state law additionally require?

    Correct answer: Certification by the State Board of Education for the covered school-bus operation.

    South Carolina separately requires State Board of Education certification for driving a covered school bus transporting these pupils to or from school. CDL endorsements and quiz practice do not replace that requirement.

  61. At an ordinary, non-emergency fuel stop in South Carolina, may a school bus's gasoline tank be filled while pupils remain aboard, even with the engine off?

    Correct answer: No; pupils may remain aboard during filling only under the statute's emergency exception.

    South Carolina prohibits filling a school bus's gasoline tank while the engine runs and, except in an emergency, while pupils are aboard. An ordinary outdoor stop is not that emergency exception; the engine restriction is separate.

  62. South Carolina's school-bus seating law permits a limited number of excess passengers on regular routes while routes are adjusted. What is the maximum period specified for that temporary provision?

    Correct answer: Twenty school days.

    The law normally limits assigned students to manufacturer-certified seating capacity and requires adequate seating area. Its limited regular-route adjustment provision cannot last more than twenty school days; it is not unlimited authority to overload a bus or ignore occupant protection.

  63. Outside an emergency, which entrance or exit does South Carolina's school-bus equipment law require people to use?

    Correct answer: The front entrance-exit.

    The statute provides for the normal front entrance-exit and a marked rear emergency exit. Except during an emergency, passengers must use the front entrance-exit rather than an emergency door or window.

  64. A pupil violates the school-bus driver's instructions during a South Carolina route. What does state law require the driver to do about the misconduct?

    Correct answer: Report the misconduct promptly to the governing head of the school.

    The driver maintains good conduct and promptly reports misconduct or violations of instructions to the school head. School administrators may be authorized to suspend or expel pupils from bus service; the driver should follow the school's procedures.
