(CNN) -- One person died Friday in a chain-reaction crash involving at least 20 cars on Interstate Highway 80 in northern California, state Highway Patrol Sgt. Curtis Fouyer told CNN.
The accident occurred about 1:30 p.m. (4:30 p.m. ET) when a truck carrying refrigerated hydrogen flipped over near Donner, California, and several cars were caught under the truck, Fouyer said.
Roads were slick in the region due to winter weather, and moments before the accident, state authorities issued a requirement that motorists use tire chains, Fouyer said. The westbound lanes of the interstate were closed after the accident, he said.
Hydrogen from the truck wasn't leaking Friday afternoon, Fouyer said.
A short time after the accident, the eastbound lanes of Interstate 80 in Truckee, California -- about 11 miles away --were also closed when several vehicles became involved in spinouts, Fouyer said.
