It takes much longer to stop on a slippery road. See and be seen. Drive with headlights on at all times. Clean your windows and exterior lights often. Approach bridges with extra caution.
Bridge decks ice up more often and more quickly than other road surfaces.
For those traveling on a long journey, check weather and road reports. If you live in an area which regularly receives snow or your profession or outside interests such as skiing or other winter sports require you to drive in winter conditions, then your vehicle should be outfitted with snow tires. Watch for road maintenance crews. Give roadside crews a wide berth as you pass them. Keep your distance behind snowplows and road sanding trucks.
