A semi-truck that caught fire on I-215 before tipping onto its side slowed traffic for awhile Wednesday.

The truck was traveling north on I-215 west near 1700 North about 10 a.m. when the rear axle of the vehicle caught fire, said Utah Highway Patrol trooper Cameron Roden.

"The truck driver said he started to pull over, and lost control of it," Roden said.

The driver tried to pull his rig over to the shoulder, but the vehicle ended up tipping onto its side. Speed did not appear to be a factor in the accident, he said.

"It appears to be more of a mechanical malfunction. The driver lost control, it made him spin sideways and tip over," Roden said.

The truck was hauling chemicals that were not hazardous and did not spill, he said. The driver was not injured. One lane of traffic was closed for over an hour while crews uprighted the rig.
