During a vehicle inspection, it is crucial to check that the air pressure gauges are giving a correct reading. These gauges are vital indicators of the air pressure in the braking system, and having accurate readings ensures that the brakes will function effectively.

Maintaining the integrity of air pressure gauges allows the driver to assess whether the air supply is within safe operating parameters, which is essential for safe driving and compliance with regulations. Ensuring that your air pressure gauges are functioning properly is a fundamental part of pre-trip inspections to maximize vehicle safety on the road.
