What is the function of the ABS in a lorry?

Explanation

Correct answer: It enables driving during emergency braking.

The ABS (Anti-lock Braking System) prevents the wheels from locking completely during heavy braking. As the wheels continue to rotate, they maintain grip and allow the vehicle to be steered. This enables the driver to steer around an obstacle even during emergency braking, which would be impossible with locked, skidding wheels.
