How do you effectively stop a vehicle with an ABS?

In the photo you can see the ABS warning light lit in yellow on the dashboard. In a vehicle with ABS you brake most effectively by pressing the brake pedal as hard as possible - answer B.

The Road Traffic Act requires braking in a way that does not cause danger, and with a sudden obstacle every metre counts. ABS itself controls the pressure in the brakes so that the wheels do not lock, so your job is to press the pedal all the way down and hold it until the vehicle stops, while steering in a safe direction. Pulse braking (answer A) is a technique for vehicles without ABS - in a vehicle with ABS it only lengthens the braking distance. Not pressing the pedal all the way (answer C) also wastes part of the braking effectiveness. Note: if the ABS warning light, like the one in the photo, does not go out after the engine is started or comes on while driving, the system is faulty - then you brake as in a vehicle without ABS.
