Conditions this morning vary across the state. Check 511 for current road conditions, and your local weather to determine what type of precipitation you may be seeing today. Plan your travel around the storm, not during - give the plows time to work. #VASnow pic.twitter.com/scQNWCW6Vt— VDOT (@VaDOT) February 20, 2019

The better news: You should have this winter driving stuff down pat. Remember: Snow doesn’t cause crashes. Poor driving decisions cause crashes. Slow down and drive to conditions. Turn on those headlights. #mnwx pic.twitter.com/qU5v9III58
