A driver suffered life-threatening injuries after multiple crashes caused a slowdown on Highway 20 in Nevada County Friday morning, authorities said.

The California Highway Patrol said it responded to Highway 20 between Grass Valley and Penn Valley around 8 a.m. after a Volkswagen rear-ended a semi-truck.
