FALMOUTH — A driver and his passenger were shaken up after a mechanical defect caused him to lose control of his sports utility vehicle on Interstate 295 northbound Sunday afternoon.

State Trooper Larry Rose said a 2006 Toyota SUV operated by 51-year-old Raymond Carter of Bowdoinham spun out of control after rear end tire rod snapped.

The vehicle hit a guardrail on the side of the road before striking a Ford F-150 pickup truck operated by 45-year-old Michael Bergeron of Freeport. Bergeron and his teenage son were not hurt.

Carter and his passenger, 53-year-old Diana Carter of Bowdoinham, complained of pain. They were evaluated by medical personnel at the scene but did not have to be hospitalized.

Both lanes of northbound traffic were closed for a few minutes, and traffic backed up to Tukey’s Bridge in Portland. The accident was reported at 3:40 p.m. Both lanes of traffic were open by 4:30 p.m.
