This article explores the different types of warning lights, what they mean, and why you should never ignore them.

Brake Warning Light

What It Means

The brake warning light can indicate several issues, from a simple oversight to a severe problem. Here are some possibilities:

Why It Matters

Brakes are essential for safe driving. According to the National Highway Traffic Safety Administration (NHTSA), brake-related issues account for approximately 22% of all car accidents in the U.S. (NHTSA). If your brake warning light is on, get your vehicle to a repair shop immediately.
