What does ABS stand for in truck terminology?

  1. Anti Brake Skidding

  2. Air Brake System

  3. Automatic Brake System

  4. Anti Lock Braking Systems

The correct answer is: Anti Lock Braking Systems

ABS stands for Anti-Lock Braking System, not Automatic Brake System or Anti Brake Skidding. While an ABS is an important component of an Air Brake System, ABS specifically refers to the mechanism that prevents the wheels from locking up during hard braking, allowing the driver to maintain control of the vehicle. In contrast, Automatic Brake System is not specific to preventing wheel lockup, and Anti Brake Skidding does not accurately describe the function of ABS. Therefore, the correct answer is D Anti Lock Braking System.
