A man came to the rescue of a semi-truck driver who was rolling down a hill Friday morning.

Police said Bill Easton spotted the rig along Grand Avenue Friday, just off the Neville Island Bridge, rolling down the road with the driver slumped over.

Easton told police he noticed something was wrong, parked his car and jumped into the cab of the truck.

“He was completely leaned over the gear shift and the truck was moving,” Easton said. “We went out onto the bridge, looked and saw the driver slumped over in his seat so we started honking and screaming.”

Police said Easton found the driver slumped over in the seat and stopped the truck from moving.

“I ran to catch the truck before it came down here. I hopped up on it and tried to wake him at first. I thought it’d be easiest for him to stop the truck, but he was unresponsive,” Easton said.

Easton parked the 40-ton truck full of oil by himself before it caused any damage.

“At a minimum it would have gone into an oncoming lane,” Ohio Township Police Chief Nortbert Micklous said. “He did a fantastic job. It’s hard to imagine. It’s amazing what he did.”

Easton said he is a volunteer firefighter and doesn’t consider himself a hero.

“There’s a lot of people who would have done the same thing if they would have seen it,” Easton said.

The 34-year-old driver of the truck is from Washington, Pa., but officials have not said what happened to him. Zappi oil truck officials have not commented on the incident.
