Police said a 17-year-old girl who was practicing how to drive broke her mother's legs after stepping on the gas pedal instead of the brake.
Sgt. Thomas Long told The Republican newspaper that the mother was sitting on a fence when she was struck Saturday morning at a movie theater parking lot.
The teen was trying to put the car in park when the accident happened. "She was stopped, but not being familiar with the vehicle, she accelerated and hit her mom," Long said.
The woman was taken to Baystate Medical Center for treatment.
Authorities cited the girl's 39-year-old father, who owned the car, for allowing an unlicensed driver to operate the vehicle.
