Drivers are being warned to slow down on wet, icy or snow-covered pavement after a number of vehicles crashed in the Saint Johnsbury area early yesterday morning.
Police responded to a total of nine crashes on Interstate 91, Routes 5 and 2 in St. Johnsbury, Lyndon and Concord after wet roads turned icy.
Most of the ice formed on bridges which tend to freeze first.
Three of the vehicles rolled over and injuries were reported in three of the crashes.
The crashes ended after the Agency of Transportation salted to the roads.
Police also advise drivers to consider putting snow tires on their vehicles.
