Authorities say an 8-year-old Boston boy backed his mother's BMW out of the driveway and crashed it into the porch of the house across the street.
Officials say neither the boy nor anyone in the home was hurt in the accident in the city's Dorchester neighborhood at about 8:30 a.m. Wednesday. The porch and foundation suffered an estimated $80,000 in damage.
The car, with its trunk ripped off and rear window smashed in, had to be towed from the scene.
Authorities say the car backed out of the driveway, across a street, between two parked cars and through a hedge before plowing into the other home. One official says the vehicle was probably traveling at about 30 miles per hour.
No names were released.
