Four people were injured — three sustained minor injuries and one sustained moderate injuries — in a four-vehicle traffic collision on Highway 101 between Los Alamos and Buellton Monday morning.

Emergency crews responded to the southbound side of the highway at around 5:08 a.m. for a report of a multi-vehicle traffic collision, according to Santa Barbara County Fire Department spokesperson Karen Cruz-Orduña.

Cruz-Orduña said one vehicle had rolled over.

Two people injured in the crash were transported by ground ambulance to the hospital, and the other two refused medical care, per Cruz-Orduña.

One lane of the highway was closed after the collision. It has since reopened.

Additional information was not immediately available.
