Sample Minnesota School Bus Test Questions

Question 1

Which situation requires a school bus driver to evacuate the students even when no train is visible?

  1. A The ABS warning lamp remains on
  2. B The bus is stalled on or next to a railroad-highway crossing
  3. C The bus is safely stopped on the shoulder and the interior is becoming warm
  4. D The bus has a minor mechanical problem while parked off the roadway

Correct answer: B – The bus is stalled on or next to a railroad-highway crossing

A school bus stalled on or adjacent to a railroad-highway crossing must be evacuated whether or not a train can be seen. The crossing itself creates an immediate risk that requires students to be moved to safety. An illuminated ABS malfunction lamp alone does not require evacuation because the regular brakes remain available.

Question 2

In Minnesota, what should students do when they must cross the road after leaving a school bus?

  1. A Run across as soon as the red lights begin flashing
  2. B Move at least 10 feet in front of the bus, make eye contact with the driver, and wait for the driver’s signal
  3. C Cross immediately if the bus has a crossing-control arm
  4. D Walk behind the bus and cross after it leaves

Correct answer: B – Move at least 10 feet in front of the bus, make eye contact with the driver, and wait for the driver’s signal

Students who must cross should move at least 10 feet in front of the bus, make eye contact with the driver, and wait for a signal that it is safe. The driver must check traffic carefully before giving that signal. A long, steady horn blast may be used to warn students not to cross.

Question 3

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

  1. A Check them only after reentering traffic
  2. B Check them once after closing the service door
  3. C Monitor them continuously
  4. D Check them at 10-second intervals

Correct answer: C – Monitor them continuously

The driver must continuously monitor the mirrors during student loading and unloading. This provides ongoing observation of students, surrounding traffic, and the bus’s danger zones. Before moving, the driver should recheck the side and crossover mirrors and account for the students.

Question 4

What is the primary purpose of inspecting a school bus?

  1. A To create additional work for maintenance personnel
  2. B To complete the school’s administrative records
  3. C To determine whether the bus is safe and find defects that could cause a breakdown or crash
  4. D To provide the driver with a break before the route

Correct answer: C – To determine whether the bus is safe and find defects that could cause a breakdown or crash

The purpose of the inspection is to determine whether the bus is safe to operate. It can reveal defects that might cause a mechanical breakdown or, more seriously, a crash. Minnesota’s CDL manual emphasizes that safety-critical components must be checked for proper working order.

Question 5

Which feature shows that a school bus is equipped with an antilock braking system?

  1. A A yellow ABS malfunction lamp on the instrument panel
  2. B An ABS certification label on the driver’s door
  3. C A red indicator mounted on a brake cylinder
  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. On newer vehicles, the lamp normally illuminates briefly at startup for a bulb check. If it remains on after the check or comes on while driving, ABS control may have been lost at one or more wheels.

Question 6

Under Minnesota law, a driver stopped for a school bus displaying flashing red lights must remain stopped until those red lights stop flashing.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

State law requires an approaching vehicle to stop at least 20 feet from a school bus displaying flashing red lights. The vehicle must not move until the red lights are no longer flashing. Drivers should remain attentive for children even after the signals are turned off.
