DAMASCUS, Va. — As many as 50 people were injured Saturday afternoon after a car plowed into parade-goers in Damascus, Virginia, a police dispatcher told CNN.

Of those injured, at least five or six were “trauma victims,” the dispatcher said.

The driver lost control of his car because of a sudden medical emergency, police said.

The accident occurred during the Hiker’s Parade at the annual Trail Days festival, which honors the famed Appalachian Trail, in the town near the Virginia-Tennessee border.

Dalton Thomson told CNN affiliate WCYB that he was pushed out of the way of the oncoming car by a hiker.
