1。 anti-lock brakes are chiefly designed to provide "steerability" in a skid. They do not activate during normal stopping. However, if used correctly in an emergency they can stop your car more safely than conventional brakes.

The results cancel each other out, said Hurd. That observation is seconded by IIHS senior vice presidents Chuck Hurley and Kim Hazelbaker, both of whom point to their group's study, which also shows no net difference in crash experience between cars with ABS and cars without them.
