A Maine State Trooper was injured Friday evening after his cruiser was hit from behind by a car on the Maine Turnpike. It's the second time in less than a week that a State Trooper has been injured on that same stretch of road, as a result of a driver failing follow Maine's move over law.

Maine State Police say Trooper Ryan Keller was parked in a breakdown lane in New Gloucester with his emergency lights activated around 5:30 Friday evening, when 22-year-old Nancy Colson of Topsham lost control of her car and hit the rear of Keller's cruiser, forcing it into a guardrail. Keller's Ford Explorer cruiser was totaled in the wreck. 

Last Friday, Trooper John Davis was injured when his cruiser was hit by a tractor-trailer that failed to move over.

Davis was also in the breakdown lane with his lights activated.

Maine's move over law requires drivers to change lanes when police, fire, ambulance, and tow truck light are activated. The law is designed to protect emergency workers and give them more space along the side of the road.
