VDOT says it is pretreating local roads and highways. The transportation agency is advising drivers to be careful on the roads tonight and to consider leaving work early.
VDOT Asks Drivers To:
Continue to closely monitor weather, as forecasts can improve or worsen quickly. Stay tuned to local media for the real-time status of weather bands before traveling, due to the likelihood for limited visibility.
If road conditions become hazardous, delay travel for your safety and to give trucks time to treat roads. Leave earlier or delay trips to avoid driving during the height of the storm.
Before traveling, check road conditions along your route at www.511virginia.org, on the free app for Apple and Android, or call 511 from any phone in Virginia.
Be aware of the potential for slick spots on areas prone to freezing such as bridges, ramps and overpasses.
Allow extra time for trips, brake lightly and allow plenty of following distance. Ensure enough gas and plenty of wiper fluid, proper tires, medication, an emergency car kit, and always use your headlights.
Give trucks plenty of room to work, because they are large, heavy and slow.
