Many newer vehicles have an Antilock Braking System (ABS). Be sure to read the vehicle owner’s manual on how to use the ABS. The ABS system will allow you to stop without skidding.
In general, if you need to stop quickly press on the brake pedal as hard as you can and keep pressing on it. You might feel the brake pedal pushing back when the ABS is working. Do not let up on the brake pedal. The ABS system will only work with the brake pedal pushed down.
If you must stop quickly and you do not have an Antilock Braking System (ABS). You can cause the vehicle to go into a skid if you brake too hard. Apply the brakes as hard as you can without locking them. If the brakes lock up, you will feel the vehicle start to skid. Quickly let up on the brake pedal. As soon as the vehicle stops skidding, push down on the brake pedal again. Keep doing this until the vehicle has stopped.
