Sample CDL School Bus Endorsement practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Brake System Inspection
When performing a pre-trip inspection of a Type C school bus, you notice a significant leak in the hydraulic brake system. The service brake pedal goes to the floor. What is the immediate course of action?
- A.Top off the brake fluid reservoir and test the brakes cautiously.
- B.Attempt to bleed the brake system to remove air and restore pressure.
- C.Check the brake fluid level and proceed if it's above the minimum mark.
- D.Report the issue to the mechanic and do not operate the bus until repaired.(Correct)
Explanation
A hydraulic brake system leak that causes the pedal to go to the floor indicates a critical failure. Operating the bus would be extremely dangerous. The bus must be taken out of service and repaired by a qualified mechanic.
- Question 2Emergency Procedures
A school bus carrying 35 passengers suddenly experiences a complete loss of steering. What is the primary safety procedure to follow?
- A.Shift to neutral and use the parking brake to slow down.
- B.Activate hazard lights and steer as much as possible using the remaining resistance.
- C.Continuously honk the horn to alert other drivers and attempt to coast to a stop.
- D.Apply the service brakes firmly and steer towards the nearest safe shoulder.(Correct)
Explanation
With a loss of steering, the driver's primary goal is to stop the vehicle safely. Applying service brakes firmly will help reduce speed, and steering towards the shoulder is the best option to get the bus out of traffic lanes.
- Question 3Emergency Exits and Alarms
During the post-trip inspection, you discover that the emergency exit door alarm is not functioning. What is the most appropriate action?
- A.Inform the supervisor that the bus can be operated but with caution.
- B.Note the malfunction in the driver's log and report it to the transportation supervisor.(Correct)
- C.Attempt to troubleshoot the alarm system yourself.
- D.Consider the alarm system a non-critical component and continue daily operations.
Explanation
The emergency exit alarm is a critical safety feature. Its malfunction must be reported immediately to the appropriate supervisor and documented. The bus should not be operated until the alarm is repaired.
