Are all vehicles with air brakes required to have a low pressure warning signal?

All vehicles equipped with air brakes must have a low air pressure warning system in place. This system is critical for ensuring the safety of the vehicle and its occupants, as it alerts the driver when the air pressure in the braking system drops to a dangerously low level.

The presence of a low pressure warning signal helps to prevent brake failure by providing an early warning that maintenance or attention is needed. This requirement is applicable to all vehicles with air brakes, regardless of their weight classification or commercial use.

While some may think that only heavy-duty vehicles or commercial vehicles require such a system, the regulation covers all vehicles with air brakes uniformly. This ensures a consistent standard for safety across different types of vehicles.
