What does ABS light mean on a car?

ABS stands for Anti-lock Braking System. The ABS light on a car indicates that there is a problem with the ABS system. This could be due to a faulty sensor, a problem with the hydraulics, or a computer issue. When the ABS light is on, it means that the ABS system is not working properly and you may not have full braking power. It's important to have the ABS light checked out by a mechanic as soon as possible.
