Four people died and multiple others were injured in a massive car crash involving at least 46 vehicles, the Ohio State Highway Patrol said Friday.Fifteen commercial vehicles were being cleared from the turnpike late Friday, and “white-out conditions persist,” highway patrol said.Buses were being used to take people from the crash site to a local facility so they could stay warm, according to the agency.“The weather outside is not favorable, and often times there are whiteout conditions, which does not make it safe for travel,” Ohio State Highway Patrol Sgt.Purpura asked people to stay home or take precautions if they have to drive, including moving slowly and allowing more space between cars."
