Seth Hartigan of Nevada traveled to see family for Mother’s Day. Upon returning home, he said he was caught off-guard with no chains.

“My concern is they won’t let me through without them,” he said.

At one point, ice pelted the area as snowdrifts created a white-knuckle drive throughout the Sierra.
