A man is lucky to be alive after a dump truck ran over his head in the Ballston area over the weekend.

The incident happened around 2:15 p.m. on Saturday, Nov. 24. According to police, the cyclist was stopped at a temporary red light next to a construction site on Quincy Street near Wilson Boulevard, when an unoccupied dump truck started rolling south on Quincy and struck him.

The man was knocked to the ground and one of the truck’s tires ran over his head, said Arlington County Police spokesman Dustin Sternbeck. The man was wearing a helmet at the time and the helmet likely saved his life. He was taken to Inova Fairfax Hospital’s trauma center with non-life-threatening injuries, Sternbeck said.

Immediately after the incident the driver of the dump truck, who had left it running and unattended next to the construction site, ran it down and managed to stop it from rolling further, according to Sternbeck. Occupational safety officials responded to the scene, inspected the truck and found multiple safety violations, he said.

Citations were issued and the truck was “taken out of service.” No word on whether any other charges are pending.
