A three-car chain reaction accident slowed traffic on Highway 32 east of Chico Thursday.
The collision happened around 9:15 a.m. in a construction zone at Highway 32 and Humboldt Road.
A line of westbound cars were stopped on Highway 32 waiting to be flagged through a construction zone.
A witness said a Jeep Cherokee approached the line of cars from behind at approximately 55 miles per hour. The Cherokee failed to stop and slammed into the back of a pickup truck, sending the pickup in the car in front of it.
No one was seriously injured.
