What is the purpose of the vehicle's anti-lock braking system (ABS) light?

The vehicle's anti-lock braking system (ABS) light serves an important purpose in indicating whether there is an issue with the ABS itself. When this light illuminates on the dashboard, it alerts the driver that the ABS is not functioning properly and may require attention. The ABS is designed to prevent wheel lock-up during hard braking, allowing the driver to maintain steering control, especially in slippery conditions. If the ABS light is on, it signals that this critical safety feature may not be operational, which could lead to reduced braking effectiveness under certain circumstances.

In contrast, the tire pressure levels are monitored by a separate system, and the battery status is indicated by a distinct light different from the ABS warning. The speed limit is not communicated through dashboard lights, making it clear that the ABS light specifically pertains to the functionality of the anti-lock braking system.
