-- Leave plenty of time to get where you're going. Be prepared to drive at least 10 miles-per-hour slower.
-- Accelerate slowly. Use your second gear if possible if the conditions are bad.
-- Allow three times more braking distance than usual, and if your brakes lock up ease off them.
-- If you have standard brakes pump them gently. If you have anti-lock brakes DO NOT pump them.
-- Drive with your headlights on.
