Gently try your brakes while driving slowly to find out just how slippery the road is. Judge how fast you can go and still stop safely. If you have conventional disc and drum brakes, apply firm, steady pressure on the brake pedal. If you hit the brake too hard, you'll momentarily lock the wheels. If you do lock the brakes, release your foot from the pedal to relieve brake pressure one or two degrees, then immediately reapply it with slightly less pressure.
Snow tires help driving during the winter months.
They give better traction and help in starting and stopping. Snow tires, however, often do not give good traction on ice. On ice and in hard packed or deep snow, tire chains help. In New Jersey, studded snow tires can be used between November 15 and April 1 of each year. To start on snow and ice, keep your engine speed low.
