School Bus Endorsement School Bus Endorsement Vehicle Inspection & Pre-Trip Procedures 1 — Questions and Answers
Question 1: During a pre-trip inspection, which component must be checked to ensure the school bus emergency exit door opens from both inside and outside?
- The door latch mechanism and panic hardware (Correct answer)
- Only the exterior handle
- The door hinge bolts only
- The window above the door
Correct answer: The door latch mechanism and panic hardware
Emergency exit doors must open from both sides so passengers can escape and rescuers can assist during an emergency.
Question 2: How often must a school bus driver perform a pre-trip inspection?
- Before every trip (Correct answer)
- Once per week
- Once per day regardless of trips
- Only after maintenance
Correct answer: Before every trip
Federal regulations require a pre-trip inspection before each trip to ensure the vehicle is in safe operating condition.
Question 3: When inspecting school bus mirrors, the driver should ensure the mirrors allow a view of:
- 200 feet to the rear and both sides of the bus (Correct answer)
- Only the area directly behind the bus
- The front bumper area only
- 50 feet to the rear
Correct answer: 200 feet to the rear and both sides of the bus
Mirrors must provide an adequate view of at least 200 feet rearward and both sides so the driver can monitor all students near the bus.
Question 4: What should a driver do if the school bus air pressure drops below the low-pressure warning level during pre-trip?
- Do not drive the bus until the air system is repaired (Correct answer)
- Drive carefully to the nearest shop
- Pump the brakes to rebuild pressure
- Reduce speed and continue the route
Correct answer: Do not drive the bus until the air system is repaired
Driving with low air pressure is dangerous because air brakes require sufficient pressure to function properly.
Question 5: Which lighting component is checked by activating the hazard lights during the pre-trip inspection?
- All four turn signal/hazard lights simultaneously (Correct answer)
- Only the headlights
- The interior dome lights
- The stop-arm lights only
Correct answer: All four turn signal/hazard lights simultaneously
Activating hazards confirms that all four corner turn signal lamps flash simultaneously and are visible to other drivers.
Question 6: During the engine compartment inspection, a school bus driver notices fluid leaking from the power steering reservoir. What is the correct action?
- Report it out of service and do not drive (Correct answer)
- Add fluid and monitor during the route
- Drive only short distances
- Ignore it if the level is above the minimum line
Correct answer: Report it out of service and do not drive
Any active fluid leak must be reported and the bus placed out of service because steering failure is a critical safety hazard.
