Q:

What is the full form of “ABS” in terms of modern vehicle brakes?

A) Advanced Braking System B) Anti-Lock Braking System
C) Assisted Braking System D) Advanced Backing System
 
Answer & Explanation Answer: B) Anti-Lock Braking System

Explanation: The full form of “ABS” in terms of modern vehicle brakes is Anti-Lock Braking System. These are modern type of braking system that prevents the vehicle from skidding. This system smoothens the process of braking and reduces sudden locking of wheels.
