Man arrested for DUI after rear-ending Pennsylvania state trooper

A Pennsylvania state trooper was injured in a vehicle collision late Wednesday night along I-476 in Marple Township. It was a little after 11:30 p.m. when investigators say the trooper was parked off the shoulder in an active construction zone with his lights on. Another car, travelling north along the interstate, was trying to get to the offramp at Exit 5 when he rear-ended the trooper's car. The trooper sustained minor injuries from the crash.
