What is the purpose of an anti-lock braking system (ABS)?

The purpose of an anti-lock braking system (ABS) is to prevent wheel lockup during hard braking. When a driver applies the brakes forcefully, especially on slippery surfaces, there's a risk that the wheels can stop rotating entirely, which can lead to a loss of control over the vehicle. ABS allows the wheels to continue rotating by automatically modulating brake pressure during intense braking situations. This not only helps maintain steering control but also reduces the stopping distance on slippery roads. As a result, drivers can maintain better control of their vehicle and reduce the likelihood of skidding or losing traction while braking suddenly.
