VIRGINIA (DC News Now) -- As more snow heads toward Virginia Friday night, state police encourage the public to prepare, plan ahead and stay safe. A winter storm warning went into effect Friday across parts of Virginia. This came as winter precipitation is expected to bring some icing in the Southwest Virginia and Hampton Roads areas into Saturday morning. VSP also noted that refreezing may persist throughout the weekend.

To prevent unnecessary traffic crashes on highways across the Commonwealth, VSP urges people to postpone travel plans and avoid driving until weather conditions improve. If you have to travel during the storm, VSP advised drivers to do the following:  Use headlights. Increasing your visibility helps you to avoid slick and dangerous spots on the road, as well as helps other drivers see you better.  Slow your speed. Though state police works closely with the Virginia Department of Transportation (VDOT) to identify problem areas on Virginia’s highways during a winter storm, drivers still must drive for conditions. Slowing your speed gives you more time to safely react and avoid a crash. Drive your vehicle based on your ability to properly maintain control of your vehicle.  What is black ice, how does it form? Don’t tailgate. You need increased stopping distance on slick road surfaces. Give yourself more space between vehicles traveling ahead of you to avoid rear-end collisions.  Buckle Up. Most crashes that occur during winter weather are caused by vehicles sliding into guardrails, off the road or other vehicles. Wearing your seat belt protects you from being thrown around the inside of your vehicle and suffering serious injury in a crash.  Check Your Vehicle. Make sure your vehicle is in good working order for the conditions. Fill up the tank in advance. Check windshield wipers, windshield wiper fluid, tire tread, battery life, etc.  Don’t leave home without a window scraper, blanket, bottled water, snack, cell phone charger and flashlight.   For the latest on road conditions and updates, call 511 or visit the Virginia Department of Transportation's website.
