If the low air pressure warning light for the air brake system activates, what should you do?

Continue driving until you reach your destination
Stop and safely park as soon as possible
Check the pressure gauges and monitor the situation
Pump the brakes to increase air pressure

The correct answer is: Stop and safely park as soon as possible

When the low air pressure warning light for the air brake system activates, stopping and safely parking as soon as possible is essential for ensuring safety. The air brake system relies on a certain amount of air pressure to function properly, and low air pressure can lead to brake failure or reduced braking capability, which poses a significant risk on the road. Continuing to drive could result in a complete loss of braking power, making it impossible to stop the vehicle safely, especially in emergency situations. While checking the pressure gauges might seem prudent, it does not address the immediate danger that low air pressure presents. Pumping the brakes to increase air pressure is not a viable solution either, as the air pressure must be sufficient to operate the braking system effectively. Therefore, prioritizing safety by stopping the vehicle safely is the most responsible course of action when the low air pressure warning light is illuminated.
