Maryland State Highway Administration officials are asking drivers to slow down on roads and highways as a winter storm passes through the area.
The agency says snow plows were deployed before the morning rush hour to treat roads. Crews are reporting drivers are going too fast for the snowy, slushy conditions.
The state has more than 1,100 people working to keep the roads clear. Still, the highway administration says drivers will find snow coverage on major interstates and secondary roads around Baltimore and points north and west. Road conditions improve south and east of Baltimore.
Officials are urging drivers to stay behind and not pass snow plows.
