What action is recommended if the air pressure gauge reads below the minimum threshold?

When the air pressure gauge indicates a reading below the minimum threshold, it is crucial to pull over and investigate the issue. Low air pressure can indicate a serious problem with the braking system, which could lead to a loss of braking power. Safety is paramount when operating a commercial vehicle, and being proactive by stopping allows you to check for potential leaks, issues with the compressor, or other mechanical failures that may affect your ability to stop safely. Addressing the problem before continuing your journey helps ensure not only your safety but also the safety of others on the road. Ignoring the low pressure and continuing to drive would be irresponsible and could lead to a catastrophic failure while driving.
