What is the purpose of the air brake test?

The purpose of the air brake test is to ensure that the air brake system is functioning correctly and safely. This is a critical safety measure because the air brake system is essential for the stopping and controlling of a commercial vehicle. The test helps to identify any potential issues, such as leaks in the system or inadequate air pressure, before the vehicle is put into operation. Conducting this test allows the driver to verify that the brakes are capable of performing their necessary functions, which is vital for safe driving and compliance with regulations. Ensuring the brakes are in proper working order prevents accidents and promotes overall road safety for both the driver and other road users.
