The Oklahoma Highway Patrol says fog and cattle on the highway led to a three-vehicle injury crash just south of Bartlesville early Friday.
Troopers said the 3:36 a.m. crash shut down the southbound lanes of Highway 75 near County Road 2400 for two hours while crews cleaned up the wreckage.
Trooper Seth Hudson says a southbound car clipped a cow standing in the roadway. Right after that, a southbound Hummer slammed into the same cow. Then, the driver of a southbound PT Cruiser struck another cow before hitting the Hummer, knocking it onto its side.
The OHP says three people from two of the vehicles, the PT Cruiser and the Hummer, were taken to a Bartlesville hospital.
Troopers said there was dense fog in the area at the time of the crash.
