A man was killed in an early morning crash Saturday on U.S. 40 west of Duchesne.

The Utah Highway Patrol said Luis Pena, 23, of Bridgeland died at the scene shortly after his pickup truck collided with a tractor-trailer truck at about 7:30 a.m. UHP trooper Luke Stradinger said it appears that Pena fell asleep at the wheel and drifted into the path of the truck, driven by 22-year-old Justin Stroud of Duchesne.

"Luis sideswiped Justin on the driver's side of the rig," Stradinger said. "Justin ran off the road to the right and came to a stop."

It took emergency crews several hours to cut Pena's body from his pickup. Stroud was not injured despite heavy damage to his truck.

An inspection of Stroud's truck by troopers found no equipment problems that would have contributed to the crash.
