At least eight vehicles crashed into each other on southbound State Route 163 Monday evening, causing traffic congestion along the freeway and prompting a Sig Alert.
The chain reaction of collisions started at about 6:35 p.m. near Friars Road when four cars were stopped in traffic and a fifth did not slow down in time, according to the California Highway Patrol.
"We were just totally stopped, sitting still and all of a sudden, the car just hit us," said Brian Butterworth, who was rear-ended.
Other vehicles were hit as car after car slammed into one another.
Three people were taken to the hospital, all with minor injuries.
