Anti-lock brakes (ABS) are designed to prevent the wheels from locking up during hard braking situations. This feature is crucial for maintaining steering control and stability, allowing the driver to steer around obstacles while braking. When a driver applies the brakes suddenly, the ABS automatically modulates brake pressure to prevent the wheels from skidding. This braking technique helps to maintain traction with the road surface, which is particularly important on slippery or uneven surfaces. As a result, the driver can retain better control of the vehicle, helping to avoid accidents and navigate safely even in emergency braking situations. This function makes ABS a significant safety enhancement for drivers in various driving conditions.
