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.

1. Question 1Pre-Trip Inspection

   During a pre-trip inspection of a Type D school bus, you notice a significant amount of play in the steering wheel, approximately 3 inches of free play. What is the maximum allowable free play for a school bus steering system according to most state regulations, and what is the primary concern if this limit is exceeded?

   • A.Maximum 3 inches; likely a minor adjustment needed.
   • B.Maximum 4 inches; indicates normal wear and tear.
   • C.Maximum 2 inches; potential for loss of steering control.(Correct)
   • D.Maximum 1 inch; requires immediate replacement of steering components.

   Explanation

   Maximum allowable free play in a school bus steering system is typically 2 inches. Excessive free play, such as 3 inches, can indicate worn steering components (e.g., tie rod ends, steering gear) and significantly increases the risk of losing steering control, especially during emergency maneuvers or on uneven surfaces.

2. Question 2Railroad Crossings

   You are driving a school bus carrying 40 elementary school students. While approaching a railroad crossing, the warning lights on the bus activate, and an audible alarm sounds indicating a potential malfunction. What is the safest and most appropriate action to take in this situation?

   • A.Immediately evacuate all students from the bus and direct them to cross the tracks on foot.
   • B.Attempt to reset the warning light system while stopped before the tracks; if it doesn't reset, then evacuate.
   • C.Continue across the tracks cautiously if no train is visible, as the alarm may be a false positive.
   • D.Stop the bus at least 15 feet from the nearest rail, activate hazard lights, and assess the situation before proceeding or evacuating.(Correct)

   Explanation

   The safest action is to stop the bus at least 15 feet from the nearest rail, activate hazard lights, and assess the situation. Malfunctioning safety equipment at a railroad crossing presents a critical hazard, and proceeding without confirmation of safety is extremely dangerous. Evacuating students onto railroad tracks is also a severe safety risk.

3. Question 3Post-Trip Inspection & Safety Equipment

   A school bus equipped with a 72-passenger capacity requires a driver to perform a post-trip inspection. You discover that one of the emergency exit windows is jammed and cannot be opened. What is the immediate and most critical follow-up action required?

   • A.Attempt to force the window open yourself; if unsuccessful, then report it.
   • B.Inform the principal and have them decide if the bus can be used for the next route.
   • C.Report the issue to the mechanic and note it on the driver's report, but the bus can still be used if other exits are functional.
   • D.Tag the bus out of service immediately and ensure it is not used until the emergency exit is repaired and certified.(Correct)

   Explanation

   Any non-functional emergency exit renders the school bus unsafe and must be tagged out of service immediately. Regulations mandate that all emergency exits must be operational for the bus to be legally and safely used. Relying on other exits or attempting repairs without proper certification is unacceptable.
