Blizzard conditions along I-80 temporarily trapped hundreds of vehicles overnight, California Highway Patrol officers told ABC News on Saturday. An estimated 200 to 300 vehicles — including a mix of passenger cars and big rigs — were stuck from approximately 5 p.m. PT Friday to 2:30 a.m. PT Saturday over Donner Summit, officers said. With the help of tow trucks, everyone was able to get out and no vehicles were abandoned, officers said. There were no injuries or medical emergencies reported.

There was no panic. Everyone knew there would be plenty to eat if the emergency continued indefinitely.
