Sample Iowa School Bus Test Questions

Question 1

When should problems or unusual conditions discovered during a school bus post-trip inspection be reported?

  1. A Immediately
  2. B At the end of the week
  3. C Whenever the driver has spare time
  4. D At the next scheduled maintenance visit

Correct answer: A – Immediately

A post-trip inspection includes checking for sleeping students, items left aboard, open doors or windows, damage, and mechanical or operational problems. Special attention should be given to school bus equipment such as mirror systems, warning lamps, and the stop arm. Any problem or special situation must be reported immediately to a supervisor or school authority.

Question 2

What should a school bus driver do when caught in strong winds?

  1. A Increase speed to leave the windy area quickly
  2. B Continue at exactly 10 mph
  3. C Avoid stopping under any circumstances
  4. D Grip the steering wheel firmly and anticipate gusts

Correct answer: D – Grip the steering wheel firmly and anticipate gusts

Strong winds can push a school bus sideways and, in extreme conditions, contribute to a rollover. Keep a firm grip on the steering wheel and anticipate gusts. Slow down to reduce the wind’s effect, or pull off the roadway and wait when necessary, and contact dispatch for information about how to proceed.

Question 3

After leaving the school bus without crossing the roadway, how far should students walk from its side?

  1. A Only far enough to clear the doorway
  2. B At least 8 feet
  3. C At least 10 feet
  4. D At least 5 feet

Correct answer: C – At least 10 feet

The Iowa CDL manual directs students to walk at least 10 feet away from the side of the bus after exiting. They should stop where the driver can plainly see them. The driver must continue monitoring the mirrors and account for every student before preparing to leave the stop.

Question 4

If time permits, what should a school bus driver do before deciding whether an emergency requires evacuation?

  1. A Shut down the engine immediately
  2. B Move every student to the front
  3. C Contact dispatch and explain the situation
  4. D Open all emergency exits

Correct answer: C – Contact dispatch and explain the situation

The driver’s first consideration is recognizing the hazard and making a timely safety decision. If time permits, the driver should contact dispatch, describe the situation, and obtain available assistance before deciding to evacuate. An immediate evacuation is still required when conditions such as fire, imminent collision, or a hazardous-material spill create urgent danger.

  4. D Stop, look, and listen

Correct answer: D – Stop, look, and listen

Iowa law requires a school bus to stop between 15 and 50 feet from the nearest rail, then look and listen in both directions. The CDL manual also directs the driver to silence noisy equipment and open the service door and driver’s window. Proceed only after checking for trains and determining that the crossing can be completed safely.

At the stop, place the transmission in Park or Neutral, set the parking brake, and activate the red lights and stop arm at the proper time.
