My Car's Brake Light Came On While Driving: What Can I Do?

As one of the most important systems in your car, brakes can be the difference between life and death, so it is no small matter if the brake system warning light on the dashboard comes on. It is particularly scary when the light comes on while driving. There are a number of reasons why this could happen, and only one is a quick fix that doesn't require you to get your vehicle seen to by a professional. For all the rest, it indicates a dangerous situation that needs immediate attention.

Reasons Your Car Brake Warning Light Comes On While Driving

Dashboard lights are there to warn you of issues with your car, and in modern cars there are a variety of warning lights that indicate problems with the brake system. The easiest thing to do is to check the meaning of the specific warning light in your owner's manual. Here are some potential reasons why you may be getting a warning light:

  • The parking brake might be engaged: In some cases, you may pull off and start driving without fully disengaging the parking brake and not noticing that the light was on. A red parking brake light will illuminate. However, if the parking/emergency brake warning light comes on and off while driving, then it may indicate a deeper problem.
  • The brake fluid might be running low: The braking system uses brake fluid to amplify the force you place on the pedal and turn it into pressure on the brakes of your car. This liquid maintains the hydraulic pressure of the braking system and is essential to its operation, so if these fluid levels run low, it can cause the brake light warning to illuminate. While there may not be a brake fluid light specifically on all cars, your parking brake illuminating serves as the warning to check your brake fluid levels.
