Sample California School Bus Test Questions

Question 1

Properly adjusted outside flat mirrors should show the sides of the bus and the rear tires touching the ground.

  1. A False
  2. B True

Correct answer: B – True

Properly adjusted outside flat mirrors should provide a view along both sides of the bus and show the rear tires where they touch the ground. They should also show approximately 200 feet, or four bus lengths, behind the vehicle. Correct adjustment helps the driver monitor traffic, students, and clearance around the bus.

Question 2

A school bus may have a tail swing of up to:

  1. A 1 foot
  2. B 3 feet
  3. C 5 feet
  4. D 7 feet

Correct answer: B – 3 feet

A school bus can have as much as three feet of tail swing. As the front of the bus turns in one direction, the rear may swing outward in the opposite direction. The driver should check the mirrors before and throughout a turn to monitor this movement and maintain clearance from nearby objects or road users.

Question 3

When unloading students at school, the driver must always remove the ignition key, even when remaining in the driver’s compartment.

  1. A False
  2. B True

Correct answer: A – False

The driver should turn off the ignition when securing the bus for unloading at school. The key must be removed if the driver leaves the driver’s compartment; removal is not stated as an unconditional requirement when the driver remains there. The driver must still secure the bus and properly supervise the unloading process.

Question 4

The California Commercial Driver Handbook contains every requirement needed to operate a school bus legally.

  1. A True
  2. B False

Correct answer: B – False

The handbook states that it does not include every federal and state requirement for operating a commercial vehicle. Its school-bus section also directs drivers to become familiar with applicable laws, regulations, and local school-district requirements. The handbook is an important study resource, but it is not the only authority a school bus driver must follow.

Question 5

How often should a school bus driver check the mirrors while students are loading or unloading?

  1. A Only after reentering traffic
  2. B Only after closing the entrance door
  3. C Continuously
  4. D Approximately every 10 seconds

Correct answer: C – Continuously

The driver should monitor all mirrors continuously during loading and unloading. Continuous observation allows the driver to watch the danger zones for students, pedestrians, traffic, and other objects. Mirror checks must continue throughout the stop rather than occurring only at one stage of the procedure.

Question 6

Which description correctly states how far the school-bus danger zones may extend?

  1. A 30 feet in front and behind, and 12 feet on each side
  2. B 12 feet in every direction around the bus
  3. C 30 feet in front, 12 feet behind, and 12 feet on each side
  4. D 12 feet in front, 30 feet behind, and 12 feet on each side

Correct answer: C – 30 feet in front, 12 feet behind, and 12 feet on each side

The California handbook states that the danger zones may extend as much as 30 feet from the front bumper and 12 feet from both sides and the rear bumper. The first 12 feet in front of the bus are identified as the most dangerous. The left side also presents added danger from passing vehicles.
