Sample Colorado School Bus Test Questions

Question 1

Before opening the service door at a student stop, what must the school bus driver do?

  1. A Turn off the engine and leave the transmission in gear
  2. B Shift into Neutral and release the parking brake
  3. C Keep the transmission in Drive while holding only the service brake
  4. D Shift into Neutral or Park and set the parking brake

Correct answer: D – Shift into Neutral or Park and set the parking brake

Colorado regulations require the driver to apply the parking brake and shift the bus into Neutral or Park before opening the service door. This procedure secures the bus during student loading or unloading. Holding only the foot brake or leaving the transmission in a drive gear does not satisfy the stated procedure.

Question 2

How should you normally brake a school bus equipped with anti-lock brakes?

  1. A Pump the brake pedal rapidly
  2. B Repeatedly fan the brakes
  3. C Release the brakes completely before the final stop
  4. D Brake as usual, using only the force needed to stop safely

Correct answer: D – Brake as usual, using only the force needed to stop safely

Use the brakes on an ABS-equipped bus in the same manner as normal brakes, applying only the force needed to stop safely and maintain control. Do not pump the brakes during emergency braking. ABS helps prevent wheel lockup, but it does not permit faster driving, closer following, or less careful braking.

Question 3

As a general rule, how much clear storage space beyond railroad tracks is needed before a school bus begins crossing?

  1. A The bus length plus 25 feet
  2. B The bus length plus 15 feet
  3. C The bus length plus 10 feet
  4. D The bus length plus 5 feet

Correct answer: B – The bus length plus 15 feet

Before crossing, the driver must verify that the area beyond the tracks can hold the entire bus with additional clearance. Colorado's rule specifies enough space for the bus plus 15 feet if stopping after the crossing becomes necessary. A driver should not enter the crossing unless this containment or storage area is available.

Question 4

What should students do before crossing the roadway after leaving a school bus?

  1. A Run across immediately after the driver opens the door
  2. B Stop, check traffic, maintain visual contact with the driver, and wait for the driver's signal
  3. C Cross without stopping whenever the bus has a crossing-control arm
  4. D Follow the first student without checking for traffic

Correct answer: B – Stop, check traffic, maintain visual contact with the driver, and wait for the driver's signal

Students should walk far enough in front of the bus to remain visible to the driver, then stop at the roadway's edge. They must look in all directions, confirm the roadway is clear, check that the bus's red lights are still flashing, and wait for the driver's signal. Students should continue watching for traffic while crossing rather than run blindly across.

Question 5

Which listed condition is specifically identified as requiring a school bus evacuation?

  1. A Downed power lines are visible nearby
  2. B The bus is stalled on or next to a railroad-highway crossing
  3. C A tornado has been sighted in the area
  4. D All of these conditions automatically require evacuation

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

The Colorado CDL manual identifies a bus stalled on or adjacent to a railroad-highway crossing as a mandatory evacuation condition. Downed power lines and a sighted tornado are factors the driver must consider when deciding whether and how to evacuate. Other mandatory conditions include a fire or fire threat, imminent collision danger, and certain hazardous-material spills.

Question 6

What must properly adjusted outside crossover mirrors show?

  1. A The roadway extending 200 feet behind the bus
  2. B The entire area along the bus behind the mirror mounts
  3. C The right and left front tires where they touch the ground
  4. D The right and left rear tires where they touch the ground

Correct answer: C – The right and left front tires where they touch the ground

Crossover mirrors should show the front danger zone from the bumper at ground level to the point where the driver's direct view begins. They must also show both front tires touching the ground and the area extending toward the service door. These mirrors are especially important while loading and unloading students.
