Introduction Regular inspection of a vehicle helps ensure the safe and reliable operation of a vehicle. Types of inspections Underhood inspection Exterior inspection Certain in-vehicle inspections Under-vehicle inspection Check fluid levels, lighting systems, etc. Faults or concerns should be noted for service or repair.

Performing a Visual Inspection Vehicle should be checked for overall roadworthiness. Owner may perform this inspection. Work in a systematic manner. Use inspection sheet. Inspect each vehicle in the same way.

Checking the Wiper Blades (1 of 2) Checked as part of the exterior inspection More than year old is ready for replacement Wiper blade and arm should be checked. Should flex at the hinge and be held firmly against the windshield by wiper arm spring Check rear wiper blade in the same way.

Checking the Wiper Blades (2 of 2) Never operate the wipers when they are dry. Never bend the arms to make better contact with the windshield. Replace if it seems to have lost its spring tension.

Inspecting the Windshield Inspected during the wiper blade inspection Scratched, scored, or pitted glass will not wipe clean. Windshields may become etched or pitted, causing the wipers to function poorly. Some small chips or cracks can be repaired with special resin and tools. Large chips or cracks larger than 3″ may be reason to replace the windshield.

Inspecting the Tires (1 of 2) Tires are checked for: Pressure Wear patterns Cuts Tread depth Tire condition is one of the most important safety considerations.

Inspecting the Tires (2 of 2) Tires are inflated using pressurized air or nitrogen to support the weight of the vehicle. Normal tire pressure varies. Recommended tire pressures for vehicle are located on the tire placard. Maximum tire pressure on the tire sidewall is the maximum pressure for that tire. Never inflate the tire above the recommended maximum pressure. 9
