A woman trying to back a vehicle toward a self-storage unit on Friday accidentally hit the accelerator instead of the brakes, striking a man who was working inside the unit, according to Steve Woodsum, the owner of Great Northern Self-Storage.

Woodsum, who also owns an auto shop next to the storage facility and witnessed the accident, said the man was taken away by ambulance, but that he was walking afterward and didn’t appear to have suffered life-threatening injuries.

There was no damage to the storage unit, Woodsum added.

“(The vehicle) was all lined up to go straight, and the young woman driving the vehicle had big boots on,” Woodsum said. “She hit the accelerator instead of the brake.”

The accident at 1697 Main St. was first reported at 2:50 p.m. Responders initially called for a Life Flight medical helicopter to take the patient away, but they canceled that request a few minutes later.

Readfield Fire Chief Lee Mank said later Friday that the incident was investigated by a Maine State Police trooper.
