RICHMOND, Va. (WRIC) -- As a winter storm moves throughout the state, the Virginia Department of Transportation (VDOT) is urging residents to stay off the roads, and providing safe driving tips to those who must travel. The department said the winter storm has caused hazardous driving conditions across much of the western and northern regions of Virginia. Most of the state-maintained roads in those areas are in "moderate condition," according to VDOT, meaning there is snow or ice on major portions of the road. "Crews are working around the clock to remove snow and treat state-maintained roads until they are passable. Snow removal operations take time, so travelers should not expect to see bare roads during — and for a period after — the storm," the department said in regard to road conditions. Residents are urged to stay off roads. If travel is absolutely essential, though, the department said drivers should use "extreme caution." VDOT recommends taking the following steps when making a trip during wintry weather: Before heading out, check the current road conditions and weather forecast. For statewide highway information, call 511, go to the 511 website or download the app. Make sure your vehicle is ready for winter: Check your brakes and tires. Check your battery and ignition system. Check your antifreeze and thermostat. Check your windshield wipers and de-icing washer fluid. Check your headlights, tail and brake lights, blinkers and emergency flashers. Check your exhaust system, heater and defroster. Check your oil. Properly lubricate door locks that may be prone to freezing. Clear snow and ice from your vehicle’s roof, hood and trunk and especially from the windows, mirrors and lights. Always wear your seat belt. Leave a few minutes early. Start out slowly in the lowest gear recommended by your vehicle's manufacturer. Be aware of potentially icy areas such as shady spots and bridges. Keep a safe distance of at least five seconds behind other vehicles and trucks that are plowing the road. Don't pass a snowplow or spreader unless it is absolutely necessary. Treat these as you would emergency response vehicles. Keep an emergency winter driving kit in your car. Give crews room to clear roads. This way, first responders can respond quickly. Don't dress children in heavy coats when they're secured in a car seat.
