Review all 64 questions with answers

  1. For a new 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.

    The S endorsement requires qualification for the passenger endorsement and a driving skills test in a school bus of the appropriate vehicle group. Practice quizzes do not satisfy these licensing or training requirements.

  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.

    Source: Colorado Commercial Driver License Manual (06/15/23), Section 10.1.1, physical PDF page 108. Reviewed September 14, 2026. ↗

  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 family asks you to move its assigned school-bus stop to another driveway. Under the RMV handbook guidance, what is needed before changing the stop?

    Correct answer: Written approval from the appropriate school-district official.

    The district establishes approved routes and stops. The handbook directs drivers not to relocate a stop without written approval from the appropriate district official; follow local procedures for reporting a safety concern.

  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. A Massachusetts school bus has an eight-lamp warning system. Which lights warn traffic as it approaches a pupil stop?

    Correct answer: The alternating amber pupil-warning lamps.

    Section 7B(7) uses amber lamps on approach for an eight-lamp system and discontinues four-way flashers for that approach function. Red pupil-warning lamps are for the stopped loading or unloading phase, not the moving approach.

  13. In the RMV handbook recommended student-stop procedure, where should the front bumper stop relative to waiting students?

    Correct answer: At least 10 feet away, so their approach remains visible.

    Section 10.2.1 recommends a complete stop with the front bumper at least 10 feet from students. This is handbook guidance, not a claim that every Massachusetts stop is governed by a separate fixed-distance statute. Follow the approved stop and local safety procedures.

  14. Under the RMV handbook stop procedure, how should you secure the bus before students board?

    Correct answer: Use Park, or Neutral if there is no Park position, and set the parking brake.

    The recommended procedure uses Park when available, otherwise Neutral, with the parking brake set at each stop. Do not substitute a transmission setting alone for securing 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. How should students board after you give the signal?

    Correct answer: Slowly, single file, using the handrail.

    Orderly, single-file boarding with the handrail reduces falls and lets you observe each student. Use the dome light when darkness makes the steps harder to see.

  17. Six children were waiting, but you 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. When are newly boarded students ready for the bus to depart?

    Correct answer: When they are seated and facing forward.

    Wait until students are seated and facing forward, then complete the exterior and traffic checks. A clear stairwell alone does not mean they are safely settled.

  20. At a drop-off stop, 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.

  23. Before crossing in front of the bus, where should a student wait for the driver's signal?

    Correct answer: At the right edge, far enough ahead for the driver to see their feet.

    The handbook teaches moving at least 10 feet ahead to a visible position at the right edge of the roadway. Students check traffic and wait for the driver's signal; local crossing procedures also apply.

  27. Where does Massachusetts Section 7B direct a school bus to receive or discharge pupils?

    Correct answer: As close as practicable to the right-hand side or edge of the way.

    Clause (7) places pupil loading and unloading as close as practicable to the right side or edge. This does not authorize an unapproved stop or remove the need to check traffic and account for pupils.

  28. You are still rolling toward a pupil stop. When may Massachusetts school-bus red pupil-warning lamps be used?

    Correct answer: When the bus is stopped to load or unload pupils, not while rolling.

    Section 7B(7) limits these red lamps to a stopped bus receiving or discharging school pupils. Keep the required stopped-bus warning while pupils enter or leave, and do not drive away before pupils who wish to cross have crossed safely.

    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. Under Massachusetts Section 7B, how often must pupils receive on-bus emergency-evacuation drills during a school year?

    Correct answer: At least twice during the school year.

    Clause (15) requires at least two on-bus emergency-evacuation drills each school year. These drills are separate from the classroom safe-riding instruction also required by the statute.

  48. How often does Section 7B require classroom instruction in safe school-bus riding practices?

    Correct answer: At least three times each school year, including once in the first week.

    Clause (15) requires at least three classroom sessions: one in the first week, one between September and January, and one between January and the end of the school year. The two required on-bus evacuation drills do not replace these sessions.

  49. A Massachusetts school bus is being used on a public highway primarily for passengers other than school pupils. What does Section 7B require?

    Correct answer: Conceal the school-bus wording and do not use the school red lights or stop arm.

    Clause (1) requires the school-bus wording to be concealed for this use and prohibits activation of the school warning lamps and stop arm. This does not remove the vehicle’s other applicable passenger-transport requirements.

  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. Backing cannot safely be avoided at an authorized location. May you put a student outside to direct the school bus?

    Correct answer: No; do not place a student outside to direct backing.

    Section 10.7.3 says never to put a student outside when backing. Avoid backing when a safer alternative exists and follow the approved procedure, using an appropriate adult lookout where available.

  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.

    At pickup, have all students aboard before unavoidable backing and watch for latecomers. At drop-off, complete any necessary backing before students unload.

  58. For a Massachusetts school bus used to transport pupils, when is the pretrip inspection required by Section 7B?

    Correct answer: Daily, before operating the bus.

    Clause (16) requires a daily pretrip inspection. A previous driver’s uneventful trip or a recent repair does not replace this inspection duty.

  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. Your Massachusetts school-bus pretrip finds a defect that may affect safe operation or cause a mechanical breakdown. How must it be reported under Section 7B?

    Correct answer: Promptly, in writing, to the employer.

    Clause (16) requires prompt written reporting to the employer of the specified defects. Reporting is not permission to operate an unsafe bus; follow the safe repair and vehicle-release procedure.

  61. A Massachusetts school bus reaches a fuel station with passengers still aboard. What does Section 7B require?

    Correct answer: Do not fuel the bus while it is occupied by passengers.

    Clause (5) prohibits fueling a school bus while it is occupied by passengers. Do not import a different state’s occupied-fueling exception into this rule; arrange a safe, authorized fueling plan.

  62. On a routine Massachusetts pupil trip with no emergency, every adequate seat is occupied. May three more pupils simply stand in the aisle?

    Correct answer: No; the normal rule requires adequate seats and pupils seated before moving.

    Section 7B(2) normally limits occupancy to adequate seating and requires pupils to be seated before moving. Its narrow emergency exception permits at most three standees, with supporting straps, handles or bars, for no more than five consecutive school days. It is not a routine capacity increase.

  63. Which places must a Massachusetts school-bus daily post-trip interior inspection include to make sure no pupils remain?

    Correct answer: Behind and underneath every seat, as well as the rest of the interior.

    Section 7B(17) expressly includes the area behind and underneath each seat in the daily post-trip interior check. Silence or an interior mirror view does not establish that the bus is empty.

  64. While a Massachusetts school bus is moving, may its operator use a mobile electronic device to handle a routine schedule message?

    Correct answer: No; routine scheduling is not the statute’s emergency exception.

    Section 7B prohibits mobile-electronic-device use while the bus is in motion except for the defined emergency uses, such as calling for medical or police help or reporting a disabled bus. An ordinary schedule message is not an emergency; hands-free operation is not a general exemption.

Knowledge practice only: this is not a school-bus driver certificate, registered ELDT, behind-the-wheel training or permission to transport pupils. Confirm RMV licensing, medical, training and testing requirements separately; the quizzes are not an emergency-response procedure.

Sources and equipment limits

39 of our shared safety scenarios retain their actual Colorado DMV-linked handbook or federal source. The other 25 use the Massachusetts RMV manual and General Laws c.90, Section 7B. Colorado-specific operating rules are excluded. In Massachusetts, do not fuel a school bus occupied by passengers; the ordinary seated-pupil rule has only a narrow statutory emergency standee exception. Follow current state rules, district procedures and equipment-specific training.
