What is the function of anti-lock brakes (ABS)?

The function of anti-lock brakes (ABS) is vital for enhancing vehicle safety, especially during emergency braking situations. ABS works by preventing the wheels from locking up when a driver applies hard braking force. This locking can cause a loss of steering control, making it difficult for the driver to maneuver around obstacles. By automatically modulating brake pressure, ABS allows the driver to maintain steering control while still slowing down, thereby reducing stopping distances on slippery surfaces and improving overall vehicle stability. This technology is particularly important in preventing skidding, which could lead to accidents, making it a crucial feature in modern vehicles.

The other options relate to different aspects of vehicle performance but do not accurately describe the primary function of ABS. For instance, while ABS can indirectly enhance traction by preventing skid, its specific role is not to improve fuel efficiency or assist with steering control directly.
