The ABS system itself also has limitations, and it still cannot get rid of certain physical laws. In both cases, the ABS system cannot provide the shortest braking distance. One is direct braking by an experienced driver on a smooth dry road. Another situation is braking on loose gravel, loose dirt, or deep snow.
Also, often on dry roads, the latest ABS systems can control slip rates in the 5%-20% range, but not all ABS brakes at the same rate or to the same extent. Although the four-wheel anti-lock braking system enables the car to brake for the shortest possible distance, it will not prevent an accident if the braking is applied too late so that it cannot come to a complete stop before colliding with an obstacle .
