If you brake hard on a slick surface, the force of the brakes may exceed the tires' grip of the road. The wheels will lock and the vehicle will skid, no matter which way the steering wheel is turned. To recover from the skid, take your foot off the brake pedal to unlock the wheels. Then straighten the front wheels as the vehicle begins to straighten out. Slow the vehicle gradually until you are at a safe speed to continue driving.
