The most important thing to do when the low air pressure warning comes on is

• A. stop and park safely as soon as possible
• B. continue driving to nearest service
• C. increase throttle
• D. ignore

Answer: (A)

When the low air pressure warning appears, the most important action is to stop and park safely as soon as possible. The air brake system needs sufficient compressed air to function; if pressure drops, braking power can fall off and, in some systems, the spring brakes may engage, potentially leading to a loss of braking control. The warning is telling you to stop now and let the system rebuild pressure before continuing. Once you’re safely parked, apply the parking brake and allow the compressor to raise the air pressure back to a safe level before resuming travel. Driving on with low air pressure won’t fix the issue and could be dangerous, while increasing throttle won’t help and ignoring the warning isn’t acceptable.
