What does ABS (Anti-lock Braking System) do under heavy braking?
- ○It locks the wheels to shorten the stopping distance
- ✓It prevents the wheels from locking, allowing the driver to steer while braking
- ○It automatically steers the car around obstacles
- ○It disables the brakes if a skid is detected

It prevents the wheels from locking, allowing the driver to steer while braking
ABS rapidly modulates the brakes to prevent wheel lock-up, which maintains steering control and helps reduce stopping distances on most surfaces.
