Cal Fire crews extinguished two small vegetation fires that broke out along northbound Highway 101 at the top of Cuesta Grade on Friday afternoon.
About 12:30 p.m., crews responded to the fires, which each burned about 400 square feet, Cal Fire spokesman Chris Elms said. They were put out within 20 minutes, he said.
California Highway Patrol also responded to the fires.
The fires are under investigation.
