If you have air brakes and the low air pressure warning device operates, you should...?

Stop as soon as possible
Continue to your destination
Check the brakes at the next stop
Increase your driving speed

The correct answer is: Stop as soon as possible

When the low air pressure warning device operates, it means that there is not enough air in the system to properly operate the brakes. Therefore, the driver should stop the vehicle as soon as possible to prevent potential accidents. Options B, C, and D are incorrect because they do not address the issue of low air pressure in the brake system. Continuing to the destination, checking the brakes at the next stop, or increasing driving speed could potentially be dangerous and put both the driver and others on the road at risk.
