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

The primary purpose of anti-lock brakes (ABS) is to prevent skidding. ABS works by preventing the wheels from locking up during hard braking. When the wheels lock, the vehicle can lose traction and control, making it much harder to steer and stop safely. By continuously monitoring the wheel speed and modulating the brake pressure accordingly, ABS allows the driver to maintain steering control while still applying maximum braking force. This technology is especially vital on slippery surfaces, such as wet or icy roads, where skidding is more likely to occur.

The other choices relate to different aspects of vehicle performance. While ABS can contribute to better stopping efficiency in terms of maintaining control, its primary role is not to stop the car faster but rather to allow for controlled braking. ABS does not have a direct impact on fuel efficiency or comfort during braking; its main focus is enhancing safety through improved control during emergency braking situations.
