Sample Colorado School Bus Test Questions

Question 1

How far from the nearest rail must a Colorado school bus stop at a railroad grade crossing?

  1. A Between 5 and 10 feet
  2. B Between 15 and 50 feet
  3. C Between 20 and 40 feet
  4. D Between 30 and 100 feet

Correct answer: B – Between 15 and 50 feet

Colorado's school transportation rule requires the bus to stop within 50 feet, but not less than 15 feet, from the nearest rail. Once stopped, the driver must look and listen for approaching trains and follow the required crossing procedure. The bus may proceed only after the crossing can be made safely.

Question 2

What must be verified when inspecting a school bus passenger lift?

  1. A The lift platform is partially extended for immediate use
  2. B No parts are leaking, damaged, or missing, and the lift is fully retracted and securely latched
  3. C The lift is one-quarter retracted and held by the hydraulic system
  4. D Only the lift's warning label and operating instructions are present

Correct answer: B – No parts are leaking, damaged, or missing, and the lift is fully retracted and securely latched

Inspect the passenger lift for leaking, damaged, or missing components and explain how its operation would be checked. When the bus is ready to travel, the lift must be completely retracted and securely latched. A partially retracted lift or one held only by hydraulic pressure is not properly secured.

Question 3

A correctly adjusted overhead inside rearview mirror eliminates every blind spot in and directly behind a school bus.

  1. A False
  2. B True

Correct answer: A – False

The statement is false. The overhead inside mirror helps the driver observe passenger activity and may provide limited visibility behind a bus with a glass-bottomed rear emergency door. Blind spots remain directly behind the driver's seat and behind the bus, so exterior side mirrors must also be used.

Question 4

After unloading, how far should students walk from the side of the school bus so the driver can see them?

  1. A At least 5 feet
  2. B At least 8 feet
  3. C At least 10 feet
  4. D Exactly 12 feet

Correct answer: C – At least 10 feet

The Colorado CDL manual directs students to walk at least 10 feet away from the side of the bus after exiting. They should remain where the driver can plainly see them. Before moving the bus, the driver must account for the students and check the mirrors for anyone who is still nearby or returning to the vehicle.

Question 5

Which view indicates that a school bus's outside convex mirrors are properly adjusted?

  1. A Two complete traffic lanes on each side, without showing the bus
  2. B The students inside the bus and the front bumper
  3. C The sides of the bus, the front of the rear tires touching the ground, and at least one lane on each side
  4. D Only the roadway extending 200 feet behind the bus

Correct answer: C – The sides of the bus, the front of the rear tires touching the ground, and at least one lane on each side

Properly adjusted convex mirrors show the entire side of the bus up to the mirror mounts, the front of the rear tires where they touch the ground, and at least one traffic lane on each side. Convex mirrors provide a wide field of view, but they distort the apparent size and distance of people and objects.

Question 6

Where should a school bus be positioned before loading or unloading students on a multilane roadway?

  1. A In the far-left lane
  2. B As far right as possible, except when blocking the lane is necessary for students to cross
  3. C Entirely on the shoulder in every situation
  4. D Centered over the line separating two lanes

Correct answer: B – As far right as possible, except when blocking the lane is necessary for students to cross

Colorado requires the bus to stop as far to the right as possible before loading or discharging students. The driver must leave adequate space for students while remaining close enough to the right to discourage vehicles from passing there. The bus may block the traffic lane when students being loaded or discharged must cross the roadway.
