Which safety feature is designed to monitor the anti-lock brake system?

The correct choice is the anti-lock brake indicator. This feature is specifically designed to monitor the functionality of the anti-lock brake system (ABS) in a vehicle. When the ABS is functioning properly, the indicator light on the dashboard will typically remain off. However, if there is a malfunction within the ABS, the indicator light will illuminate, alerting the driver that there is an issue that needs to be addressed. This monitoring is crucial for ensuring optimal braking performance, especially in slippery conditions where wheel locking can lead to loss of control.

In contrast, other features such as windshield wipers, low fuel indicators, and airbag readiness indicators serve different purposes and do not have any direct connection to the monitoring of the anti-lock brake system. Windshield wipers are related to visibility during adverse weather conditions, a low fuel indicator alerts drivers to fuel levels, and airbag readiness indicators inform drivers about the operational status of airbags in the vehicle. Each component has its specific role in vehicle safety and functionality, but only the anti-lock brake indicator is linked directly to the ABS.
