When you hear a low air pressure warning, what immediate action should be taken?

Check air pressure gauges
Continue driving cautiously
Stop and safely park the vehicle
Decrease your speed gradually

The correct answer is: Stop and safely park the vehicle

When you hear a low air pressure warning, the immediate action to take is to stop and safely park the vehicle. This is crucial because low air pressure can indicate a significant issue with the air brake system in commercial vehicles. Air brakes rely on proper air pressure to function effectively; therefore, a warning signal suggests that the air pressure is dropping to a level where it may no longer be safe to operate the vehicle. In the interest of safety for both the driver and surrounding road users, stopping the vehicle in a safe location allows for the necessary inspection and repairs, preventing potential brake failure. Continuing to drive, even cautiously, can lead to a more serious situation if the brakes become inoperable. Checking air pressure gauges or simply decreasing speed does not address the root problem, which is the low air pressure that could compromise braking ability significantly. Prioritizing immediate action to halt the vehicle ensures safety on the road.
