Semi-Truck Jackknifes on I-15 Near Grantville, Driver Killed

The driver of a UPS semi-truck was killed Tuesday night when the big rig slid off of rain-slicked freeway lanes in Grantville, the CHP confirmed.

The crash was reported just after 6 p.m. along northbound Interstate 15, just south of the I-8 interchange. Both the cabin and the trailer of the semi-truck flipped upside down and came to rest on the right shoulder of the freeway, CHP Officer Kenneth Jackman said.

Traffic crews did not clear the semi-truck from the area until nearly 7 a.m. Wednesday. Traffic during the morning commute was impacted from the accident.

CHP has yet to confirm what factors, weather included, led to the crash, but Jackman said driver may have had trouble handling a slight curve and downslope.

The driver has not been identified. A UPS spokesperson released the following statement shortly after the accident:

"We are heartbroken by the loss of our employee, and extend our deepest condolences to his family and friends. We are respectfully deferring questions about this incident to the investigating authorities."

Slick roads from rain are likely to give way to icy conditions farther east when snow is expected to fall as low as 3,000 feet in elevation.
