An Ohio man was killed Tuesday afternoon after he got out of his truck and was hit by a sport utility vehicle on Interstate 75 in Lexington.
At least two more people were killed in Western Kentucky as rain and ice slickened roads across Kentucky.
Late Tuesday evening, traffic was backed up for miles on the interstates in Central and Eastern Kentucky.
In Lexington, at least 50 accidents had been reported on the hazardous roads to Lexington police since 1 p.m.
"It is solid ice," said Lexington Police Assistant Chief Steve Stanley. "You cannot walk. Ice skates would be appropriate, but you cannot walk."
Paul Sturgill, 55, of Beechmont, Ohio, died after a wreck at 3:25 p.m. Tuesday on Interstate 75, according to the Fayette County Coroner's office. He was pronounced dead at University of Kentucky Hospital at 3:45 p.m.
The man was driving north on I-75 on the bridge over Interstate 64 when his Dodge Dakota lost control and struck the west side barrier wall, Lexington police said. He got out of his truck to inspect the damage and was hit by a Toyota 4-Runner.
The driver of that car, Steven R. Fichtelman, 26, was also injured.
Louisville police spokesman Phil Russell said rain contributed to at least two accidents. One person died Tuesday afternoon when a car went off a road in eastern Louisville. Then, just after 2:30 p.m., Russell said, a driver lost control of a car on a slick Gene Snyder Freeway, hitting a firefighter and an emergency medical worker.
Earlier in the day, Kentucky State Police said Kenneth R. Smallwood, 57, of Louisville died when his truck skidded off an icy road near Dawson Springs in Western Kentucky.
About 8:30 p.m., the Kentucky Transportation Cabinet reported a 36-mile stretch of Interstate 64 from the Rowan-Carter county line to Cannonsburg in Boyd County was closed due to icy conditions and multiple crashes.
About 9:30 p.m., traffic was at a standstill for at least 45 minutes because of icy conditions on a 13-mile stretch of I-75 around the Grant-Scott County line, a state police dispatcher said.
"It is extremely important that folks in the affected areas stay off the roads if at all possible," said Transportation Cabinet Secretary Joe Prather. "Our crews will work full force, along with our snow and ice contractors, until favorable conditions are restored."
