A Texas Department of Public Safety trooper was injured Sunday night after his patrol car was hit by a pickup driven by his son.

Trooper Bob Sims was working patrol Sunday evening and was on the way to have dinner with his family when the crash happened near the intersection of U.S. Highway 180 and State Highway 67 east of Breckenridge at about 7 p.m.

Cody, his son, was following the trooper’s cruiser in a pickup together with his wife, Jessah, and Bob Sims’ wife, Linda, as they all headed to a restaurant.

Bob Sims then “sees a violator so he pulls up on the side of the road,” said DPS spokesman Senior Trooper Sparky Dean.

“He made a U-turn to stop the violator but his son didn’t recognize what (Bob Sims) was doing.”

The pickup then crashed into the driver’s side door of Bob Sims’ cruiser.

Bob Sims was flown by helicopter to a Fort Worth hospital where he is being treated for a broken pelvis. He is listed with non-life threatening injuries.

The three occupants in the pickup were transported to a Breckenridge hospital.  Cody and Jessah Sims were treated and released while Linda remains in the hospital with non-incapacitating injuries.
