Police said two men who were inside a dump truck when it rolled over and crashed at the base of Teton Pass Monday evening were uninjured and unlicensed.
Wyoming Highway Trooper Damon Bowen said after the crash the men left the scene on foot, got into a van with another unlicensed driver and took off.
They got about a mile down the road before they were pulled over and brought back to the crash site.
There were open beer cans inside the truck but the men were not intoxicated, troopers said.
The truck was being used for a commercial roofing job that the men have been working in Teton Village, Bowen said. The truck, which has Oklahoma plates, was totaled and lacked a commercial transportation number, according to troopers.
Nails and other roofing items were strewn across Highway 22. Jackson Hole Fire/EMS cleared the road of debris.
The two men in their early thirties from Lewisville, Texas refused medical treatment, police said.
They were arrested and charged with leaving the scene of an accident, failure to report an accident and no seat belts.
Trooper Andy Jackson said the men were also in violation of federal motor carrier safety statutes: no Department of Transportation number, no log book, no commercial driver's license and no medical card.
"It poses a huge safety concern for all drivers of Teton Pass," Jackson said. "They are lucky no one got killed."
After investigating, Jackson concluded the truck lost its brakes at a high rate of speed before flipping.
The defendants' employer is unknown.
