When should drivers check the air pressure gauge during operation?

Checking the air pressure gauge continuously while driving is essential for maintaining safe operation of a vehicle equipped with air brakes. The air pressure gauge provides real-time information about the brake system's air supply pressure. This helps the driver assess whether the air brake system is functioning correctly and whether there is sufficient air pressure to operate the brakes effectively.

Constant monitoring allows the driver to detect any significant drops in air pressure that could indicate a problem, such as a leak in the air system or a malfunctioning compressor. Being aware of the air pressure status is vital because if the pressure drops below the minimum operating level, the brakes may fail, leading to dangerous situations.

This practice is part of safe driving protocol and ensures that the driver can respond quickly to any issues with the air brake system, enhancing overall road safety.
