Item
1. Inspect the engine, body, cab, and chassis to make sure that they are clean. There should
not be excessive oil or grease.
Item
2. Check the steering mechanism to make sure it is in good condition. It should not be bent or
broken or be leaking lubricant.
Item
3. Check the horn. It should be mounted securely and be loud enough to serve its purpose.
Item
4. Inspect the windshields for cracks and any defects that would make the vehicle unsafe.
Check the windshield wipers and the defroster to make sure that they are in good working
condition.
Item
5. Check to see that there is at least one spare fuse for each kind of fuse installed or that the
vehicle has an overload circuit breaker.
Item
6. Check the rear view mirrors. There must be one on each side of the vehicle. Make sure

least two Class 1 BC-rated portable fire extinguishers. One must be mounted outside the
cab on the driver's side, and one must be mounted inside the cab.
Item
9. Check all lights, light switches, and reflectors, including the clearance lights (on top of
the
trailer), turn signals, and reflectors. High and low beams and emergency flashers on both
front and rear must work properly. Make sure that lights, signals, and reflectors are free of
dirt and grease and that there are no broken lenses.
