A semitrailer driver from Georgia died in a multi-vehicle pileup Thursday morning in western Oklahoma. The crash happened shortly before 1:30 a.m. Thursday along Interstate 40 near Clinton. The overturned semitrailer caused traffic to come to a standstill on the icy roadway. Five other vehicles, many of which also were semitrailers, also crashed into the semi."We had multiple slide-off collisions between the 71-mile marker and Weatherford," Steven Cornell, with the Oklahoma Highway Patrol, said. "Because of the slowdown and the traffic backup, we had a semi strike several other vehicles."Troopers said the driver of the overturned semitrailer was killed. The Oklahoma Highway Patrol identified the victim as 35-year-old Hassan Mousa of Stone Mountain, Georgia.His passenger was taken to OU Medical Center in Oklahoma City in serious condition.Authorities said the 10 others involved in the crash weren't injured. The deadly pileup is under investigation, but troopers said the weather likely played a factor."It is passable, but it's very deceptive and it's very spotty," Cornell said. "So, it'll be OK for a few miles, and then all of a sudden it'll be black ice, which really causes problems because traffic is traveling at highway speeds. When they come upon these bad spots, that really causes the problems."Top HeadlinesThird round of ice brings more slick, dangerous road conditions to Oklahoma One dead after multi-vehicle crash involving semitrailers in Custer County Person dies in weather-related crash on highway in Payne County, OHP says Reward of up to $50K offered following armed robbery of USPS mail carrier in Edmond Oklahoma parent has scary warning after nearly losing 6-year-old son to strep throat Small Oklahoma town holds rich history as one of state’s original 'All Black' towns
