HERMANTOWN, MN (KDAL) - Hermantown Police are investigating a one car accident in the 3900 block of Haines Road around 6:10 on Monday night. The vehicle, driven by a 27 year old Duluth man, was southbound when it went off the west side of the road, through some front yards, knocking down a power pole and crashing into a tree. The car had severe damage and the impact with the tree knocked the engine from the vehicle. The driver was the lone occupant of the car and was treated at the scene by first responders and ambulance personnel. He declined further medical treatment. Hermantown Police say alcohol was not a factor but say fatigue may have played a role in the accident.
