At least 7 people were involved in a suspected DUI crash on Southbound Highway 101 north of Los Berros Road.
The California Highway Patrol and Cal Fire San Luis Obispo responded to the crash early Saturday morning.
CHP said two vehicles were involved. Officials say one vehicle collided with the RV, causing it to veer off the road.
The driver of that vehicle was apprehended and arrested for suspected DUI.
A tweet by Cal Fire shows crews on the scene of the overturned RV, just off the Highway.
