Question 7998
What is the function of the ABS anti-lock braking system?
- It prevents the wheels from locking during braking.
- It makes the tires wear less.
- It prevents the wheels from locking only on dry roadways.
Show answer and explanation
Correct answer: It prevents the wheels from locking during braking.
ABS prevents the wheels from locking during braking. Sensors measure the rotation of each wheel, and when one is about to lock, a control unit reduces the brake pressure at that wheel until it starts turning again. It works on any road surface and helps most on wet, icy, or snowy surfaces.
