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

To help save fuel

To assist with parking

To help maintain steering control during hard braking

The purpose of an anti-lock braking system (ABS) is to help maintain steering control during hard braking. ABS prevents the wheels from locking up when the driver applies the brakes suddenly, which is especially critical in emergency situations. When a vehicle's wheels lock, it can lead to a loss of control and skidding, making it very difficult for the driver to steer the vehicle. By preventing wheel lock-up, ABS allows the driver to maintain steering capability, enabling them to maneuver around obstacles and maintain stability while braking hard.

This technology is particularly beneficial in wet or slippery road conditions where maintaining control can be more challenging. Consequently, drivers can stop more safely and effectively without sacrificing their ability to steer the vehicle, which is a key advantage of the ABS system.
