What should you do if the low pressure warning light turns on?

Ignore it
Continue driving
Stop and park the vehicle
Check air levels while driving

The correct answer is: Stop and park the vehicle

When the low pressure warning light activates, it is an indication that the air pressure in the braking system is below a safe level. This warning is a critical alert that should not be ignored, as operating the vehicle under these conditions could lead to brake failure or a loss of control. Stopping and parking the vehicle is the appropriate action to take, as it allows for the immediate assessment of the air brake system and prevents potential accidents or further damage. In this situation, continuing to drive could compromise safety, as the vehicle's braking capabilities may be significantly impaired. Similarly, ignoring the warning or merely checking air levels while driving would also pose serious risks, as these actions would not address the potentially hazardous brake condition. The only responsible course of action when faced with low pressure in the brake system is to pull over safely, stop, and ensure that the system is functioning properly before resuming travel.
