A pickup truck with a flatbed trailer that was carrying 32 logs was stopped by the Teton Pass truck arrestor Tuesday evening.
The driver refused treatment and did not have serious injuries, Jackson Hole Fire/EMS Fire Marshal and incident commander Kathy Clay said.
Some of the logs got tossed over the side of Teton Pass, Clay said.
"The truck is obviously demolished," she said.
Wyoming Highway Patrol is investigating the incident, Wyoming Department of Transportation spokesperson Stephanie Harsha said.
"Traffic is moving slowly," Harsha said.
