Maine State Police and the Androscoggin County Sheriff’s Office are investigating a deadly crash.

Police say a driver falling asleep at the wheel may be to blame for the death of a pedestrian who was struck by her vehicle.

Shortly before 7:30 a.m. on Route 26 in Poland Wednesday morning, police say, an SUV went off the road and struck a pedestrian.

Androscoggin County Chief Deputy William Gagne said the female driver told them she had just finished working an overnight shift and was driving home when, she said, she fell asleep at the wheel.

Gagne says her SUV drifted off the road, hit the pedestrian, and ending up crashing into some trees.

“The car went off the road and a preliminary investigation shows that she struck the pedestrian, who is a male in his 40s. The male died at the scene,” Gagne said.

Gagne said the female driver was taken to the hospital with minor injuries. He said a blood alcohol test will be taken, which is a routine procedure.

Police said they had a preliminary identification Wednesday on the man who was hit and killed. They were trying to reach his family before releasing his name.

Officers are also trying to determine why he was out on the shoulder of Route 26.

The National Highway Traffic Safety Administration says drowsy driving is a factor in more than 100,000 crashes each year, resulting in more than 6,500 deaths and 80,000 injuries.
