What does ABS stand for in vehicles?

ABS stands for Anti-lock Braking System. This system is designed to prevent the wheels from locking up during braking, particularly in emergency situations or on slippery surfaces. When a driver applies the brakes, ABS uses sensors to monitor the speed of each wheel. If it detects that a wheel is about to lock up, it rapidly modulates the brake pressure to that wheel, allowing it to keep turning and maintain traction with the road. This technology significantly increases control and stability while braking, helping to reduce stopping distances and prevent skidding, ultimately enhancing vehicle safety.

The other options, while they sound plausible, do not accurately describe the function or purpose of ABS. Automatic Brake System, Alternative Brake System, and Advanced Brake System do not exist in the same standardized context as Anti-lock Braking System and fail to convey the specific safety features and advantages associated with ABS technology.
