Two drivers must stop quickly on a snowy road. Driver A's car has anti-lock brakes (ABS). Driver B's car has conventional brakes, and B's wheels lock. What should each driver do?

Correct answer: A keeps steady pressure without pumping; B releases, then reapplies a little more lightly.

Why

Know which brake system your car has before winter, because the right technique is different. With ABS, keep a foot on the brake pedal and do not pump it, and steer where you want to go. With conventional disc and drum brakes, use firm, steady pressure; if the wheels lock, release the pedal and reapply at once with slightly less pressure, repeating with less and less pressure until the car is under control. Snow tires help on snow but not on ice, where tire chains give the best traction.
