Ben Carpenter was unharmed but was taken to a hospital as a precaution. He had been secured to his wheelchair by a seat belt. Carpenter, who has muscular dystrophy, told a television station that he thought he might not make it through the ride.
"I was probably thinking that this is going to keep going and not stop anywhere, 50 or 60 miles somewhere," he told WOOD-TV of Grand Rapids.
Ben Carpenter's father, Donald, told The Associated Press that his son had started to cross at an intersection Wednesday afternoon in Paw Paw, about 140 miles west of Detroit. The light changed to green while his son was in front of a semi, which started moving.
The wheelchair's handles became lodged in the grille, the father said, and the wild ride started.
Motorists called police on their cell phones, and a pair of undercover police officers who happened to be nearby saw what was happening. They pulled the truck over and told the disbelieving driver, Donald Carpenter said.
The chair was undamaged except for losing most of the rubber on its wheels, he said.
"It's a very bad story that ended very well," he said. "We're just thrilled that he's still around."
