What is the proper technique when the vehicle's ABS activates during braking?

• A. Release the brake to reset ABS.
• B. Pump the brakes vigorously.
• C. Brake with light pressure and wait.
• D. Apply firm, continuous pedal pressure and let the ABS modulate braking.

Answer: (D)

When ABS activates, you should keep your foot firmly on the brake pedal and hold it there so the system can do its work. The anti-lock brake system is designed to prevent wheel lock by rapidly pulsing brake pressure, which preserves steering control. If you release the brake or pump it, you interrupt that modulation and can lose braking effectiveness and stability. You may feel the pedal pulse and hear a buzzing or grinding sound, which is normal and a sign the system is working.

Keeping steady pressure lets the ABS modulate braking automatically, allowing you to steer around obstacles while still braking as aggressively as conditions allow.
