LAKEWOOD, Wash. (AP) — Authorities in Pierce County have reported two state troopers were injured after one trooper crashed into another’s patrol car as they were responding to a single-vehicle accident on a rain-soaked highway.

Spokesman Ryan Burke said a trooper arrived on scene this morning just before 2:30 on Interstate 5 where a driver had fallen asleep and struck a barrier.

Burke said a second trooper lost control of his patrol car and smashed into the first trooper’s car, which then collided with the civilian’s car.

Both troopers were treated for minor injuries. The original driver was not injured in either crash.
