What is the function of an Anti-Lock Braking System (ABS)?

The function of an Anti-Lock Braking System (ABS) is to help maintain steering ability under hard braking. When a driver applies the brakes suddenly, especially on slippery surfaces, the wheels can lock up, leading to a loss of control over the vehicle. ABS prevents the wheels from locking by automatically modulating brake pressure. This allows the driver to continue steering while braking hard, enhancing control and stability during emergency situations. This is particularly crucial in avoiding obstacles and maintaining directional control, which can significantly reduce the risk of accidents.

Other options do not accurately describe the role of ABS. For instance, preventing skidding during acceleration pertains more to traction control systems, while merging into traffic is outside the scope of braking systems. Enhancing fuel efficiency is not a direct function of ABS, as its primary focus is on safety and control rather than improving the vehicle's fuel consumption.
