What should you do if your brake warning light comes on while driving?

If your brake warning light illuminates while driving, it is crucial to safely pull over and check the air brake pressure. The brake warning light is an indication that there is a potential issue with the braking system, which could be related to insufficient air pressure or other malfunctions that may compromise braking effectiveness.

By pulling over safely, you allow yourself the opportunity to inspect the air brake pressure and address any underlying issues before they pose a risk to your safety. This action helps ensure that your vehicle remains in a safe operating condition, preventing possible brake failure or accidents while on the road. Ignoring the warning light or attempting to compensate by altering your driving behavior could lead to dangerous situations, as it does not address the root problem indicated by the warning system.
