Sample California School Bus Test Questions

Question 1

On a California school bus manufactured on or after July 1, 1993, how many red and amber signal warning lamps make up the overhead system?

  1. A 2
  2. B 4
  3. C 6
  4. D 8

Correct answer: D – 8

CVC § 25257 requires an amber warning-light system in addition to the red flashing-light system on school buses manufactured on or after July 1, 1993. The applicable lighting standard specifies two red and two amber signal lamps at the front and the same arrangement at the rear. That makes eight overhead warning lamps in total.

Question 2

Which feature identifies a school bus as being equipped with anti-lock brakes?

  1. A A yellow ABS malfunction lamp on the instrument panel
  2. B A special statement on the driver-side door label
  3. C A red indicator mounted on a brake chamber
  4. D A yellow warning lamp on the exterior left side of the bus

Correct answer: A – A yellow ABS malfunction lamp on the instrument panel

A school bus equipped with ABS has a yellow ABS malfunction lamp on its instrument panel. The lamp warns the driver if the anti-lock system develops a fault. An ABS malfunction does not eliminate the regular brakes, but the system should be serviced promptly.

Question 3

Approximately how far in front of the bus should students move before crossing the roadway?

  1. A 6 feet
  2. B 8 feet
  3. C 10 feet
  4. D 12 feet

Correct answer: D – 12 feet

The school-bus danger-zone diagram identifies the first 12 feet in front of the bus as the most dangerous area and places the walking area beyond that point. Students who must cross are required to walk in front of the bus. California law also requires the driver to escort specified younger pupils and verify that everyone has crossed safely before moving the bus.

Question 4

When arriving to pick up students, where should the school bus stop?

  1. A With the front bumper directly beside the waiting students
  2. B With the front bumper at least 10 feet from the students
  3. C Past the designated stop so students approach from behind
  4. D About 6 feet from the students

Correct answer: B – With the front bumper at least 10 feet from the students

The bus should come to a full stop with its front bumper at least 10 feet from students waiting at the designated stop. This requires the students to walk toward the entrance, giving the driver a better view of their movements. The driver must continue checking the mirrors and danger zones throughout the stop.

Question 5

A post-trip inspection reveals a mechanical problem or unusual condition. When should it be reported?

  1. A Immediately
  2. B At the end of the next driving shift
  3. C Whenever reporting is convenient
  4. D At the next scheduled maintenance visit

Correct answer: A – Immediately

Problems or unusual situations found while checking the bus should be reported immediately to a supervisor or school authority. The post-trip inspection includes looking for mechanical or operational problems, especially those involving school-bus equipment such as mirrors, warning lamps, and stop arms. Delaying the report could leave an identified problem unaddressed.

Question 6

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

  1. A Shut down the engine before evaluating the danger
  2. B Move every student toward the front exit
  3. C Contact the dispatcher and explain the situation
  4. D Tell the students that evacuation will not be necessary

Correct answer: C – Contact the dispatcher and explain the situation

If time permits, the driver should contact the dispatcher and describe the situation before deciding whether to evacuate. This instruction does not justify delaying when an immediate danger requires evacuation, such as a fire, an imminent collision, or a bus stalled on railroad tracks. The decision must be timely and based on student safety.
