If the low air pressure warning comes on, what is the first action you should take?

• A. Stop
• B. Continue driving to the next exit
• C. Check the mirrors
• D. Pump the brakes

Answer: (A)

When the low air pressure warning comes on, it means the brake system may not have enough air to stop safely. The first action is to stop at a safe location and park. Then check the air pressure gauge and look for leaks or other causes of the drop. You should not continue driving because braking power could be compromised. Pumping the brakes won’t restore the system’s pressure and isn’t a fix, and simply checking mirrors won’t address the braking issue. Stopping now lets you inspect the problem and bring the vehicle to a safe operating state before continuing.
