FAIRFIELD — Police are investigating a single-vehicle crash that occurred Friday when a Jeep traveling south on Norridgewock Road went into the breakdown lane and flipped upside down in the road.

The operator, Bobbie Jo Dumas, 51, of Skowhegan, was taken by Delta Ambulance to Thayer Center for Health in Waterville after the crash and was treated for non-life-threatening injuries and released, according to a news release from Casey J. Dugas, public information officer for the Fairfield Police Department. She was the sole occupant of the Jeep.

At 10:12 a.m. Friday, police, Delta and Fairfield-Benton Emergency Services responded to the rollover in the area of 219 Norridgewock Road and found a 2014 Jeep Patriot upside down in the road with the operator seal-belted in, according to Dugas.

“Further investigation found that the Jeep was traveling south on the Norridgewock Road and for a reason yet to be determined, drifted into the breakdown lane,” the release says. “A dump truck and trailer registered to Pine Tree Waste of Fairfield was legally parked in the breakdown lane while equipment was being unloaded. The Jeep continued south, partially in the breakdown lane and struck one of the ramps on the trailer, causing the Jeep to roll over.”

Pine Tree Waste employees were in the area of the trailer at the time of the crash but were able to avoid injury, according to police. Fairfield Public Works also responded to the scene and “good Samaritans” stopped to render aid, the release says.

“No charges are expected to be filed at this time,” it says.
