COALVILLE -- Authorities say speed may be a factor in a rollover that killed a 67-year-old semitrailer driver in Summit County.
Utah Highway Patrol officials say Kenneth Groberg of Clinton died in the crash that happened about 8:30 p.m. Thursday on the interchange of Interstates 80 and 84.
Troopers say Groberg was pulling a flatbed trailer and taking the off-ramp to go west on I-84 when he failed to make a turn and went off the road.
The vehicle overturned and the cab was crushed, killing Groberg.
The accident closed traffic lanes for about six hours.
