"I'm trying to figure out how I'm going to stop this potentially 70,000-pound dump truck," he said.
He says he first saw the truck take out a telephone pole before veering off to the right. It went through a restaurant parking lot, smashed through a wooden fence and then finally came to a rest against a curb on 43rd Street.
Enters says a Good Samaritan had jumped in the passenger side and turned off the ignition and Enters then activated the air brake system to keep the truck from moving.
They found the driver seizing and unresponsive. Enters says he tried to prevent the man from injuring himself or activating any controls on the truck.
"He doesn't recall anything happening, he doesn't recall the crash at all actually," said Enters.
Greenfield Fire arrived shortly after and took the driver to the hospital. He's expected to be OK.
"We receive training in different maneuvers and techniques to try and stop vehicles," said Enters. "It all goes out the window when you have a dump truck. I think it was a blessing that it ended the way it did."
