Because the wheels don't lock, drivers have the ability to steer around hazards if they are unable to stop in time. ABS can improve vehicle stability, steerability and stopping capability. When the braking force created by the driver is greater than the tire can handle, the wheel can lock up. Locked wheels can create vehicle instability problems and prevent steering around obstacles in the road. Stopping distance on many slippery surfaces will also increase with locked wheels.
ABS can also prevent tire damage.
Locked wheels on dry asphalt or concrete can quickly create flat spots on tires, which can cause an annoying vibration while driving. Most anti-lock brake systems will indicate their operation by pulsations in the brake pedal and a noticeable sound. If the driver notices these pulsations and sounds, it is an indication that the roads are slippery. Speed and following distance should therefore be adjusted. To reap the maximum safety benefits of ABS, drivers must know how to use the system correctly.
