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 1Braking Systems
A school bus is equipped with a hydraulic braking system. During a pre-trip inspection, you notice that the brake pedal sinks to the floor when applied with steady pressure. This condition most likely indicates which of the following?
- A.Low brake fluid level or a leak in the hydraulic system.(Correct)
- B.Air in the brake lines that requires bleeding.
- C.Worn brake pads that need immediate replacement.
- D.A malfunctioning brake light switch.
Explanation
A brake pedal sinking to the floor under steady pressure signifies a loss of hydraulic pressure, typically due to a low fluid level or a leak within the system. The fluid is essential for transmitting braking force.
- Question 2Railroad Crossings
You are driving a school bus carrying 40 students and encounter a railroad crossing. The warning lights are flashing, and the crossing gate is down. What is the correct procedure?
- A.Stop at least 15 feet from the nearest rail, open the entrance door, turn off the engine and listen for a train, then proceed only when safe.(Correct)
- B.Stop at the crossing, check for traffic, and proceed cautiously if no train is visible.
- C.Continue driving through the crossing if you can see clearly in both directions.
- D.Stop, engage the parking brake, and have a student flag traffic while you check for trains.
Explanation
Federal and state regulations require school buses to stop at all railroad crossings. The procedure involves stopping at least 15 feet from the tracks, opening the door to listen, shutting off the engine to improve hearing, and proceeding only when certain it is safe.
- Question 3Special Needs Transportation
A school bus is transporting students with special needs. A student in a wheelchair requires assistance to board. You have a hydraulic lift. What is the maximum safe angle for the lift platform to prevent tipping or sliding?
- A.The angle is irrelevant as long as the wheelchair is secured.
- B.The lift platform's angle is determined by the bus's incline, not a fixed maximum.
- C.The lift platform should be kept as close to vertical as possible for stability.
- D.The lift platform should not exceed a 5-degree angle from the horizontal.(Correct)
Explanation
The lift platform should not operate at an angle exceeding 5 degrees from the horizontal to ensure the safety of the passenger and the stability of the lift mechanism. This prevents the wheelchair from rolling or the lift from destabilizing.
