Sample Oregon School Bus Test Questions

Question 1

Which dashboard observation indicates that a school bus is equipped with ABS?

  1. A. A yellow ABS malfunction lamp comes on during the startup check
  2. B. A certification label appears on the driver-side door
  3. C. A red indicator lamp appears on a brake chamber
  4. D. A yellow lamp appears on the exterior left side of the bus

Correct answer: A. – A yellow ABS malfunction lamp comes on during the startup check

An ABS-equipped school bus has a yellow ABS malfunction lamp on its instrument panel. On newer vehicles, the lamp normally illuminates during the startup bulb check and then goes out quickly. If it remains on after the check or comes on while driving, ABS control may be unavailable at one or more wheels.

Question 2

What is the primary purpose of the overhead inside rearview mirror on a school bus?

  1. A. To let the driver check personal appearance
  2. B. To provide a complete view of traffic behind the bus
  3. C. To replace the required post-trip inspection
  4. D. To observe activity inside the passenger compartment

Correct answer: D. – To observe activity inside the passenger compartment

The overhead inside mirror is primarily used to monitor passenger activity. It should be adjusted so the driver can see all students, including those seated directly behind the driver. Its view behind the bus is limited, so the exterior side mirrors must be used to monitor approaching traffic.

Question 3

Which distances correctly describe the danger zone around a school bus?

  1. A. 30 feet in front and behind, and 10 feet on each side
  2. B. 10 feet on every side of the bus
  3. C. Up to 30 feet in front, 10 feet behind, and 10 feet on each side
  4. D. 10 feet in front, 30 feet behind, and 10 feet on each side

Correct answer: C. – Up to 30 feet in front, 10 feet behind, and 10 feet on each side

The Oregon manual describes a danger zone extending as much as 30 feet in front of the bus, with the first 10 feet being the most dangerous. It also extends 10 feet from each side and 10 feet behind the rear bumper. The area to the left is especially hazardous because vehicles may pass there.

Question 4

What is the final check before fully opening the service door and signaling students to board?

  1. A. Confirm that all traffic has stopped
  2. B. Confirm that the students are already seated
  3. C. Shut off the engine and remove the key
  4. D. Check that the rear emergency door is locked

Correct answer: A. – Confirm that all traffic has stopped

After stopping, securing the transmission and parking brake, and activating the red lights and stop arm, the driver must check traffic again. The service door should not be opened completely and students should not be signaled to approach until all traffic has stopped. This final check helps protect students entering the danger zone.

Question 5

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

  1. A. Increase speed to pass through the windy area quickly
  2. B. Continue at exactly 10 mph regardless of conditions
  3. C. Remain on the road rather than stopping to wait
  4. D. Grip the wheel firmly, anticipate gusts, and reduce speed

Correct answer: D. – Grip the wheel firmly, anticipate gusts, and reduce speed

The Oregon manual warns that strong winds can push a school bus sideways or even tip it over. The driver should maintain a strong grip on the steering wheel, anticipate gusts, and slow down. When conditions require it, the driver may pull off the roadway and wait and should contact the dispatcher for further information.

Question 6

An Oregon school bus driver only needs to learn operating procedures once and need not remain familiar with applicable rules.

  1. A. TRUE
  2. B. FALSE

Correct answer: B. – FALSE

School bus drivers must be thoroughly familiar with the laws, regulations, and procedures that apply to their work. School transportation practices can also be affected by local school-district requirements. A driver is responsible for knowing and following the requirements currently governing the route and operation.
