UTAH COUNTY, Utah — Two people are injured and three lanes of I-15 are closed after a box truck rollover in Utah County Monday morning.
According to the Utah Highway Patrol, the crash happened on southbound I-15 near mile marker 267.
"The driver looks like he may have fallen asleep. That's what we're looking into," said UHP spokesman Sgt. Cameron Roden of UHP. "The passenger in the vehicle says it looks like he was drifting off to the side, tried to wake him up and, as he did, that's when he lost control."
Roden said the box truck struck a median wall, overturned and blocked the two left-most lanes of the freeway. UHP closed a third lane to make room for crews to get the truck back on its wheels and off the road.
The driver suffered a serious head injury and the passenger suffered minor cuts and scratches. None of the injuries are life-threatening.
Roden said it's important for drivers to avoid driving while fatigued.
"Especially when there's another person in the car that can switch and can drive the vehicle, we'd rather prevent that and have them switch before the fatigue becomes a problem," Roden said.
