New Jersey Air Brakes Practice Exam

What should you do when a low air pressure warning comes on?

Continue driving until the next stop Stop and safely park as soon as possible Accelerate to build pressure Check for leaks while driving

Correct Answer:

Stop and safely park as soon as possible

Explanation:

When a low air pressure warning activates, the proper action is to stop and safely park as soon as possible. This response is critical because low air pressure in an air brake system can lead to brake failure, putting the driver, passengers, and others on the road at significant risk. Stopping promptly ensures that you can address the issue without compromising safety. Once parked, you can then inspect the system for leaks or other malfunctions that could have caused the drop in air pressure. Continuing to drive, accelerating to build pressure, or checking for leaks while driving poses dangers not only to yourself but also to others on the roadway, making those actions inappropriate in response to a low air pressure warning.
