What should you check regarding the air pressure during your vehicle inspection?

Checking the air pressure gauge accuracy and system functionality is crucial during vehicle inspections because the air pressure gauges provide essential information about the braking system and overall functionality of the vehicle's air supply. An accurate air pressure gauge ensures that the driver can monitor the levels accurately, which is vital for safe operation of air brakes. If the gauges are malfunctioning or inaccurate, the driver might not receive critical alerts about low air pressure situations that can lead to brake failure.

The air system pressure is vital for maintaining control of the vehicle, as it influences both stopping power and overall stability. Regularly verifying the accuracy of these gauges allows for early detection of issues that could compromise safety. It's also an integral part of ensuring all systems are operating within specified limits and that emergency systems are ready to activate when necessary.
