What are the three major parts of a vehicle inspection?

The three major parts of a vehicle inspection are the pre-trip inspection, en route inspection, and post-trip inspection. This structured approach ensures that commercial drivers thoroughly check their vehicles at different stages of operation, which is crucial for maintaining safety on the road.

The pre-trip inspection is conducted before starting a trip and involves a comprehensive assessment of the vehicle's critical systems, including brakes, lights, tires, and fluid levels. This step is vital for identifying any potential safety issues that could arise during the trip.

The en route inspection occurs while the driver is on the road, typically during rest breaks. It allows the driver to check for any changes or new issues that may have developed during the trip, ensuring that the vehicle remains in safe operating condition.

Lastly, the post-trip inspection is done after completing a trip. It focuses on identifying any damage or wear that occurred during the trip, allowing the driver to address maintenance needs promptly, which is essential for the vehicle's longevity and safety in future operations.

This systematic approach of inspecting the vehicle before, during, and after trips is fundamental for safety and compliance with regulations, helping prevent accidents and breakdowns.
