Which statement about ABS is correct?

• A. ABS refers to Anti-lock Braking Systems
• B. ABS prevents all skids on any surface
• C. ABS makes braking longer during wet conditions
• D. ABS requires no maintenance

Answer: (A)

ABS stands for Anti-lock Braking System. The main idea is that this system prevents the wheels from locking up when you brake hard, so you can keep steering control and avoid spinning out. It does this by using wheel-speed sensors and a hydraulic modulator to pulse braking pressure at each wheel, keeping the wheels turning rather than skidding. That’s why the statement is correct: it accurately identifies ABS as an anti-lock braking system. The other ideas aren’t right because ABS doesn’t guarantee no skids on every surface, especially if the tires are worn or the road is extremely slick. It also doesn’t make braking longer in wet conditions; in many situations it helps maintain steering and can shorten stopping distances by preventing wheel lock. And it isn’t maintenance-free—sensors, pumps, and valves can wear or fail, so regular checks are important.
