PITTSBURGH — Two vehicles plowed into a herd of cows that had wandered onto the Pennsylvania Turnpike early Sunday, killing three of the animals and leaving two with injuries that prompted officials to euthanize them, state police said.

The five people in the vehicles were all wearing seat belts and were unhurt.

A tractor-trailer and a van struck the cows simultaneously at about 5:46 a.m. amid heavy fog in North Sewickley Township in Beaver County.

Three of the cows died immediately. Two were euthanized at the scene because of severe injuries. State police said the drivers could not have avoided the cows because of the animals' location and the fog. Both vehicles sustained substantial front-end damage.

State police said they do not expect to file charges.
