Monitoring air tank conditions at all times is crucial to prevent brake failure because the braking system in commercial vehicles relies heavily on air pressure for functionality. The air tanks store compressed air that powers the brakes, and if this system experiences a drop in pressure or any leaks, it can lead to brake failure. This is particularly vital since commercial vehicles often carry heavy loads, and any loss of braking capability can lead to severe accidents.

The braking system operates on a specific range of air pressure, and any deviations can indicate problems that need immediate attention. Routine checks not only ensure that the air tanks are functioning properly, but they also enhance overall vehicle safety and compliance with regulations. Therefore, constant vigilance is essential, regardless of the driving conditions or length of the trip, to maintain safe operational standards.
