A CareFlite medical helicopter flew a man to an area hospital, following a collision between a semi-truck and Chevy Suburban on Monday afternoon.

Waxahachie police, paramedics and firefighters responded to the scene at about 4 p.m. on U.S. Highway 287 and Parks School House Road.

The man, who was the driver of the Suburban, was originally placed in a CareFlite ground ambulance, but was later transported by the helicopter. As of press time, the extent of the driver’s injuries or why he was flown wasn’t known.

“The SUV attempted to come across and turn on Parks School House Road, and he said he just started rolling out and didn’t see the 18-wheeler,” said Clay Sibley, a Waxahachie police officer on scene, adding the driver’s airbags deployed. “The 18-wheeler — he went under it, and the trailer went on top of him. When I talked to him for the very first time, he was coherent and speaking.”

The SUV sustained heavy damage while the semi-truck had little to no external damage. Both were towed from the scene, as crews worked to clear a debris trail that was about half a mile between the wrecked Chevy and where the semi-truck came to a stop.

The southbound lanes of U.S. Highway 287 were shut down and traffic was diverted onto Parks School House Road, around the accident scene. Those re-directed weren’t allowed to turn around, and had to then drive southbound on U.S. Business 287 for about a mile before getting back on the highway.

The accident is under investigation.
