What does ABS stand for in vehicles?

Automatic Braking System
Anti-Lock Brake System
Advanced Braking System
Adaptive Brake Safety

The correct answer is: Anti-Lock Brake System

The correct answer is based on the definition and function of ABS in vehicles, which stands for Anti-Lock Brake System. This system is designed to prevent the wheels from locking up during braking, especially in emergency stopping situations. When a driver applies the brakes suddenly, the ABS modulates brake pressure to allow the wheels to continue turning rather than skidding. This helps maintain steering control and reduces stopping distances on slippery surfaces, enhancing overall vehicle safety. The other options refer to brake systems or technologies that do not accurately describe ABS. For example, Automatic Braking System, while a real concept, refers to systems that can automatically apply the brakes without driver intervention, which is not the primary function of ABS. Similarly, Advanced Braking System and Adaptive Brake Safety do not correspond directly to the recognized terminology used in automotive safety technology. Hence, understanding ABS helps drivers recognize its importance in modern vehicles for safe driving practices.
