Does the provision of ABS (Anti-lock Braking System) in a car make it safer? Support your answer?

This is actually a physics question, so it probably has something to do with force and momentum of the car/person, I just have no clue.





Thank you in advance guys, it's be great help. (:|||It has to do with several factors. The ABS system pulses pulses the brakes on and off, so that the brakes are first on full until the wheel starts to skid, then backed off, then applied again. This takes advantage of the fact that friction is higher initially, then goes down if the tire starts to slide. The ABS keeps the force at that point of max friction, and this best stopping force.





The second advantage, is that, since the tires do not lock up and slide, the driver still has control of the car and can steer it. Steering in combination with brakes could avoid an accident, whereas if the wheels are locked up you cannot steer.





A third advantage, more subtle, is that computer control of the brakes, required for ABS, allows other features to be added to the car that adds to the safety. Such as tire pressure monitor, traction control, and stability control.
