A Washington State Patrol car was involved in a collision Thursday night on Highway 20 east of Sedro-Woolley.
Trooper Mark Francis says the trooper had made a U-turn with lights activated when he was hit by a car that crossed the center line.
Francis says the other driver, a 44-year-old Arlington woman, apparently over-reacted because she was impaired by alcohol.
Francis says the trooper and the Arlington woman were not hurt. But the woman's brother, who was a passenger in her car, was taken to a Seattle hospital.
