What feature does the anti-lock braking system (ABS) provide for drivers?

The anti-lock braking system (ABS) is designed primarily to prevent wheel lock-up during braking. When a driver applies the brakes too hard, especially on slippery surfaces, the wheels can lock up, causing the vehicle to skid. ABS helps to prevent this by modulating the brake pressure to each wheel, ensuring that they continue to rotate (and therefore maintain traction) while slowing down. This capability allows drivers to maintain steering control while braking hard, which is particularly crucial in emergency situations. As a result, ABS contributes significantly to vehicle safety by enhancing the driver's ability to maneuver and avoid obstacles during abrupt braking scenarios.
