Review all 20 questions with answers

  1. A passenger wants to leave a suitcase in the aisle beside an emergency exit because the ride is short. What should you require?

    Correct answer: Stow it securely without obstructing an aisle, doorway, or exit.

    Passenger baggage must not block access or become a moving hazard. A short journey does not make an obstructed escape path safe.

  2. Before carrying passengers, you find an emergency door that does not close securely. What is the appropriate conclusion?

    Correct answer: The defect must be addressed before operating the bus with passengers.

    The bus inspection includes properly operating doors, exits, and warning devices. Do not substitute an improvised restraint that defeats emergency access.

  3. A bus passes its exterior walk-around, but a passenger seat is loose and a handhold is damaged. Is the passenger-area inspection complete?

    Correct answer: No; passenger seats and handholds must also be safe and secure.

    Interior safety checks include seats, handholds, aisles, steps, and emergency equipment. Exterior condition alone is not enough to establish passenger safety.

  4. A passenger has just boarded your transit bus and is still finding a secure position. When should you begin moving?

    Correct answer: After the passenger is seated or otherwise braced, then accelerate smoothly.

    Wait for boarding passengers to be seated or braced. Smooth acceleration helps prevent falls.

  5. A disruptive adult passenger is making continued bus operation unsafe. Which response follows the manual’s safety guidance?

    Correct answer: Manage the problem at a safe location rather than putting the person off where it would be unsafe.

    Disruptive riders must not distract the driver into unsafe operation. The manual warns against discharging a rider where it would be unsafe.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 4.3.2 At Stops, disruptive riders; printed 4-3, physical PDF page 73; reader lines 5586–5592. ↗

  6. You signal to leave a bus stop, but nearby traffic has not made room. What is the safe assumption?

    Correct answer: The signal does not guarantee a gap; check traffic and move only when safe.

    The manual warns against assuming that signaling gives you the right of way when leaving a stop. Observe the traffic and use a safe opportunity to merge.

  7. A disabled bus must be towed, and passengers can safely get off first. What is the manual’s guidance?

    Correct answer: Unload the passengers before towing.

    The manual advises against towing with passengers aboard unless unloading would be unsafe. In that exceptional situation, tow only to the nearest safe unloading place.

  8. Opening a transit bus door activates a brake-door interlock. Can that device replace the parking brake when securing the bus?

    Correct answer: No; use the proper parking brake rather than relying on the interlock.

    A brake-door interlock is not the parking brake. Follow the bus’s proper parking and securement procedure.

  9. A child is close to the front bumper below the driver’s direct view. Which school-bus mirrors are specifically intended to help check this danger zone?

    Correct answer: The correctly adjusted front crossover mirrors.

    Crossover mirrors show areas immediately in front of the bus and near the front wheels and service door. Use all mirrors in a systematic check; no single mirror covers every danger zone.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.1.5 Outside Left and Right Side Crossover Mirrors; printed 10-2, physical PDF page 128; reader lines 10044–10069. ↗

  10. You counted a child at the stop, but cannot account for that child after the others board. What should happen before the bus moves?

    Correct answer: Secure the bus, take the key, and check around and underneath it.

    The driver must account for children before departure. If a child outside cannot be located, secure the vehicle and inspect the surrounding danger zones.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.2.2 Loading Procedures; printed 10-4, physical PDF page 130; reader lines 10153–10175. ↗

  11. What should students be taught to do if they drop an item beside the bus during unloading?

    Correct answer: Leave it, move to a safe place, and get the driver’s attention.

    A child reaching for a dropped item may disappear from the driver’s view. The safe instruction is to leave it and notify the driver from outside the danger zone.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.2.5 Special Dangers of Loading and Unloading, Dropped or Forgotten Objects; printed 10-5, physical PDF page 131; reader lines 10305–10318. ↗

  12. The final school-bus stop is complete and the bus sounds empty. What check should still be made at the end of the route?

    Correct answer: Walk through and around the bus, checking especially for sleeping students and other problems.

    A physical post-trip inspection can find sleeping students, belongings, damage, and equipment problems that a quick mirror glance misses.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.2.6 Post-trip Inspection; printed 10-6, physical PDF page 132; reader lines 10327–10342. ↗

  13. After stopping a school bus at a railroad crossing, how can you improve the check for an approaching train?

    Correct answer: Silence passengers and noisy equipment, open the service door and driver’s window, and look and listen.

    The manual recommends reducing noise and opening the service door and driver's window to look and listen. Follow applicable state and local school-bus procedures as well; inactive warning lights do not prove the tracks are clear.

  14. A school bus stalls on the tracks and a train is approaching. What direction should evacuated students move?

    Correct answer: Away from the tracks and toward the approaching train, at an angle away from the bus.

    Get everyone out and clear immediately. Moving away from the tracks toward the approaching train helps avoid the likely path of debris if the train hits the bus.

  15. While children are unloading, two students inside begin arguing. What should remain your immediate focus?

    Correct answer: The children outside and the unloading danger zones; address the behavior once they are safe.

    Loading and unloading require the driver’s full outside attention. If needed, stop and secure the bus at a safe place to deal with a behavior problem after the unloading students are safe.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.5.1 Don't Deal with On-bus Problems When Loading and Unloading; 10.5.2 Handling Serious Problems; printed 10-9, physical PDF page 135; reader lines 10608–10628. ↗

  16. At an approved drop-off maneuver, backing is unavoidable and no safer option exists. Should students get off before or after the bus backs?

    Correct answer: After backing, so students are not outside the bus during the maneuver.

    Avoid backing wherever possible. If it is unavoidable, follow the lookout and inspection procedures and never back while students are outside; at a drop-off, back before unloading.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.7.3 Backing; printed 10-11, physical PDF page 137; reader lines 10751–10777. ↗

  17. A school bus is parked close to a roadside object. As the driver steers away, why must the rear overhang be watched in the mirrors?

    Correct answer: The tail can swing toward nearby objects on the side opposite the turn.

    A bus’s rear overhang can swing outward as it turns. Check mirrors before and during the turn to protect the clearance beside the rear of the bus.

    Source: Iowa DOT-hosted CDL Manual, Hy-Brid October 2023; section text Version July 2017 (older source, not verified as current catalog edition). 10.7.4 Tail Swing; printed 10-11, physical PDF page 137; reader lines 10778–10781. ↗

  18. Strong gusts are pushing a school bus sideways. What is the manual’s recommended response?

    Correct answer: Hold the wheel firmly, reduce speed, and stop safely off the roadway if necessary while coordinating with dispatch.

    The broad side of a bus can catch strong winds. Anticipate gusts, slow down, and wait safely if conditions cannot be managed.

  19. A shipment is subject to hazardous-materials shipping-paper requirements, but the shipper says the paperwork will be emailed after you leave. What should you do?

    Correct answer: Do not accept it for transportation until the required, properly prepared shipping paper is available.

    This shipment requires shipping papers. Labels or a promise of later paperwork do not replace the properly prepared hazard information needed before accepting it for transportation.

  20. You leave the controls of a truck carrying a hazardous-materials shipment that requires shipping papers. Where should those papers remain?

    Correct answer: In the driver-side door holder or on the driver’s seat, readily identifiable.

    Responders must be able to find the papers promptly. At the controls, keep them within reach while belted and visible or in the driver-door holder; away from the controls, use that holder or the driver’s seat.
