What procedure must be performed on the air brake system before starting a trip?

Performing a pre-trip inspection on the air brake system is a critical procedure that ensures the safety and functionality of the vehicle before starting a trip. This inspection involves checking various components of the air brake system, including air chambers, brake pads, hoses, and connections, to verify that everything is in proper working order. It allows the driver to identify any potential issues, such as air leaks or worn components, that could affect the performance of the brakes while on the road.

The pre-trip inspection is required by federal regulations and is essential for commercial drivers to ensure that the vehicle is safe to operate. This proactive measure helps prevent accidents caused by brake failure or malfunction, ensuring the safety of the driver, passengers, and other road users.
