Off-Road Abs

Four-wheel-drive vehicles are equipped with Off-Road ABS. Off-Road ABS provides more sustained wheel lockup than normal ABS for improved stopping performance on plowable surfaces like loose dirt, gravel, sand and mud. Such plowable surfaces move out of the way as the tires roll on them and form a wedge in front of the tires during braking because more sustained wheel lock up causes the tires to drag and the loose surface to build up in front of the tires, helping to stop the vehicle. A vehicle with normal ABS requires a longer stopping distance on the same terrain because the wheels continue rotating, not allowing the drag and build up material in front of the tires.
