Vehicle Inspection and Defect Reporting
The exam tests the pre-trip and post-trip inspection and your duty to report defects in writing. A school bus is inspected every day it is used, and the driver is the last line of defense.
Pre-trip
Use a systematic walk-around: lights and reflectors, tires and wheels, brakes and air pressure, fluids and leaks, belts and hoses, mirrors, stop arm, crossing gate, emergency exits and buzzers, first aid kit, fire extinguisher, body-fluid kit, and seats. Start the engine and check gauges and warning lights, including ABS. Test the service brake and parking brake.
Post-trip
Walk the full length of the bus, check every seat and the aisle for sleeping students and left items, close windows, and secure the bus. Report any defect on the Driver Vehicle Inspection Report at the end of the day.
Defect rule
If a defect affects safe operation, do not drive the bus. Report it and use another bus. Minor defects still go on the written report.
Worked example
During pre-trip, the right rear turn signal does not flash. You report it and take the bus out of service until repaired. Reasoning: turn signals are required equipment and a following driver cannot see your intentions; "it worked yesterday" is not a defense.
Traps
- Skipping the post-trip walk-through.
- Assuming the mechanic will notice.
- Reporting verbally but not in writing.
- Not testing the emergency door buzzer or ABS light.
