POCATELLO, Idaho – A dense layer of freezing fog led to a crash involving dozens of cars and trucks near Pocatello, Idaho, Monday morning, leaving several injured.
The initial crash occurred around 8 a.m. MST as a thick fog engulfed Interstate 86 just west of Pocatello, according to the Idaho State Police (ISP). Eastbound vehicles suddenly slowed as they encountered the fog bank, leading to multiple chain-reaction crashes, ISP said.
In all, about 30 vehicles collided, including multiple semi-trucks, troopers said.
One person was sent by ambulance to a local hospital for treatment of minor injuries, while several others headed to the hospital in personal vehicles, according to the ISP. The freeway was closed for seven hours for highway and emergency crews to clear the wreckage.
Temperatures at the time of the crash at nearby Pocatello Regional Airport were around 5 degrees, with freezing fog reported throughout the morning.
The ISP says the crash remains under investigation.
