I’m currently training to drive a school bus for the Bellevue School District.The most challenging part of training is memorizing the pre-trip inspection. It’snine pages of different components of the bus that you have to check and verbalize.For the real test at the Department of Licensing you have to go through the pre-tripinspection by memory. Below is what you have to do:
Check that all external lights and reflective equipment are clean and functional,light and reflector checks include:
Front of Vehicle
headlights, high beams, emergency flashers, left turn signal, right turn signal, warningyellows, warning reds, and stop paddle lights
Rear of Vehicle
emergency flashers, left turn signal, right turn signal, warning yellows, warningreds, stop paddle lights, back up lights and taillight
Clearance Lights and Reflectors – check that all reflective equipment is cleanand functional. Check that all lenses are clean, not damaged and not missing.
Clearance Lights and Reflectors and Reflective Tape.
Air Brake Checks
Turn the bus off and put the key in the battery charge position. Release the parkingbrake. Then fully apply the service brake and state that the air leakage rate forthis vehicle is no more than three psi per one minute. Watch the air gauges for oneminute. At the end of one minute state how much air was lost. Then start fanning yourservice brake. State to the tester that a low air warning device should come on beforethe air drops to sixty psi. When it comes on state to the tester at what psi it cameon. Continue fanning the service brake. State that the park brake should come on somewherebetween 20 and 45 psi. When the park brake comes on state to the tester where it cameon at.
The park break is on, the bus is in neutral, start the engine.
With the engine running the air pressure will build. State that the air pressure willbuild until the air governor cuts it off between 100 and 125 psi. State when the airgovernor cuts off.
Cab Engine Inspection
Parking Brake. Apply only the parking break, shift into a lower gear and slowly accelerate.
Service Brake. Release the park break, slowly accelerate then apply the service brake.
