Which statement best describes the functionality of ABS?

The functionality of ABS, or Anti-lock Braking System, is best described as allowing tires to maintain traction with the road during braking. When a driver applies the brakes suddenly, the ABS system automatically modulates brake pressure to prevent the wheels from locking up. This means that rather than skidding or losing control, the driver can maintain steering ability and control of the vehicle while still coming to a stop more efficiently.

The system uses sensors to monitor the speed of each wheel and releases and reapplies the brakes rapidly if it detects a wheel is about to lock. This helps to maximize the vehicle's stopping power while also maintaining traction, allowing the driver to navigate safely even in adverse road conditions.
