Which statement about ABS is true?

• A. It reduces braking ability on gravel
• B. It only works on vehicles with four-wheel drive
• C. It activates as the wheels are about to lock up
• D. It requires steering wheel to be straight

Answer: (C)

ABS keeps you in control by preventing wheel lock during hard braking. It does this by quickly sensing when a wheel is about to stop rotating and momentarily releasing brake pressure, then reapplying it. That pulsing action prevents skidding and lets you steer around hazards, which is the key benefit of ABS.

So the true statement is that ABS activates as the wheels are about to lock up. It doesn’t only work on four-wheel drive vehicles, nor does it reduce braking ability on gravel; it’s designed to maintain steering control by preventing lockup. You don’t have to keep the steering wheel straight—ABS will pulse while you steer to navigate obstacles.
