A hit-and-run driver yelled obscenities at a Platteville man pinned between two vehicles after a crash Sunday in the town of Hazel Green, authorities said. 

The Grant County Sheriff's Department is seeking the public's help in identifying a vehicle involved in an accident at Highway 80 and Louisburg Road in the evening. 

The sheriff's department said that during Sunday's winter storm, treacherous road conditions caused two crashes involving three vehicles. 

Brandon Monahan, 20, was southbound on Highway 80 when he rear-ended 41-year-old Laurie Splinter of rural Hazel Green due to blowing snow and whiteout conditions. Splinter was driving her Kia SUV slowly due to poor visibility.  

Officials said that while Monahan was out of his Chevrolet Cavalier assessing the damage to the two vehicles, a third vehicle rear-ended Monahan's car, pinning Monahan between the SUV and his car. 

The sheriff's department said the third driver yelled obscentities at Monahan to get out of the road and drove away. Monahan was able to free himself from between the vehicles but suffered severe leg injuries. He was taken to Mercy Hospital in Dubuque. 

Witnesses told deputies the third vehicle was a dark-colored SUV. Anyone with information regarding the hit-and-run is asked to call the Grant County Sheriff's Department or Crime Stoppers. 

The report said Splinter suffered minor injuries in the accident.
