What does a low air pressure alarm indicate?

A low air pressure alarm indicates that the air pressure in the air brake system has dropped below safe levels. This warning signal is crucial because air brakes rely on pressurized air to operate effectively. If the pressure becomes too low, it compromises the braking system's performance, which can lead to unsafe driving conditions.

Understanding this alarm is vital for any driver operating a vehicle with air brakes, as it serves as an early warning system. Addressing low air pressure promptly ensures that the brakes remain responsive and prevents potential brake failure, which could result in accidents. Monitoring air pressure levels and responding to alarms are integral parts of maintaining safe operation of a vehicle equipped with air brakes.
