If driving decrease your speed and leave yourself plenty of room to stop, you should allow at least three times more space than usual between you and the car in front of you. Brake gently to avoid skidding. If your wheels start to lock up, ease off the brake. Even at temperatures above freezing, if the conditions are wet, you might encounter ice in shady areas or on exposed roadways like bridges. Listen to the radio or TV for warnings and obey the instructions from disaster management officers.
