What is a primary function of the ABS system on a vehicle?

• A. It helps prevent wheel lockup during braking
• B. It accelerates the vehicle automatically
• C. It reduces engine power
• D. It improves steering wheel grip in turns

Answer: (A)

ABS’s main purpose is to prevent wheel lock during braking, so you can steer while you brake hard. When you push the brake pedal with force, a wheel can stop rotating and the tire may skid, making steering difficult. ABS uses wheel-speed sensors and a control unit to detect impending lockup. If a wheel is about to stop spinning, the system momentarily releases and then reapplies brake pressure to that wheel, repeating this fast cycle. This keeps the tire in a rolling state, preserving directional control and reducing the chance of a skid, especially on slippery surfaces. The other options aren’t functions of ABS— ABS doesn’t automatically accelerate the vehicle, nor does it reduce engine power. And while it helps you maintain control during braking, it doesn’t specifically increase steering grip in turns.
