A woman was flown by helicopter to a nearby hospital after the horse-drawn wagon she was riding on was rear-ended by car on North Washington Road on Sunday.

CONCORD TWP — A family's fun outing on a crisp autumn day turned scary Sunday afternoon when a car rear-ended their horse-drawn hay wagon on Route 138, authorities said.

The 3:45 p.m. crash upended and destroyed the wooden wagon, apparently throwing off and injuring its three occupants, who all live nearby.

Tina L. Porter, 52, was flown from the scene by medical helicopter to a Pittsburgh hospital with injuries that her father said included a cut and a bump on the back of her head. She also had right shoulder pain.

Porter was riding on the wagon that was hitched to a team of two horses that her husband, Brandon W. Porter, 38, was leading. Tina Porter's 8-year-old grandson was also on the wagon.

The boy suffered an apparent minor foot injury. Emlenton Area Ambulance took him to Butler Memorial Hospital. Karns City Regional Ambulance took Brandon Porter to the Butler hospital to be examined for unknown injuries also believed to be minor.

The horses also appeared to have been cut but any injuries were not immediately known.

Justin D. Fierst, 30, of Hilliards, who was driving the 2013 Nissan Sentra, and his wife, Kaitlin S. Fierst, 24, a passenger, went by private vehicle to the Butler hospital to be evaluated for possibly minor injuries. Kaitlin may have been cut by flying glass, authorities said.

“They were on a pleasure ride,” Reid Campbell, assistant chief for the West Sunbury Volunteer Fire Department, said of the Porters.

The family regularly takes such hay wagon rides on Sundays, friends noted. The couple owns both horses and the wagon.

The Porters were traveling west on Route 138, also known as North Washington Road, when the car came up behind them.

Trooper Joshua Osche said Justin Fierst was rounding a curve and clearing some kind of window obstruction. Fierst also told police the sun was in his eyes.

He steered into the eastbound lane in an attempt to avoid hitting the back of the wagon, which had a triangle-shaped reflector on the back.

But the car hit the wagon and ended on the grass south of Route 138. The wagon's front wheel axle was dislodged and the surface of wooden boards was badly damaged. The wagon ended on the right shoulder of the road.

Friends of the Porter family said the backs of the horses' legs apparently were cut by the front of the wagon being forced into them.

The animals, which stayed attached after the crash, were quickly loaded onto a trailer and taken back to their owners' property.

A wrecker eventually towed the car, which sustained severe front-end damage. A skid steer was called in and removed the wagon remains.

Osche said the investigation continues and police have made no decision if charges would be filed.
