You are driving a vehicle fitted with anti-lock brakes. You need to stop in an emergency. You should apply the footbrake

Explanation: Look well ahead down the road as you drive and give yourself time and space to react safely to any hazards. You may have to stop in an emergency due to a misjudgement by another driver or a hazard arising suddenly such as a child running out into the road. In this case, if your vehicle has anti-lock brakes, you should apply the brakes immediately and keep them firmly applied until you stop.
