Consider using a turnout - when it is safe to do so - whenever traffic backs up behind you.  A turnout road sign means that the turnout is paved.  Not all paved turnouts have a road sign.  Most turnouts are unpaved, with dirt and or gravel.   Unpaved turnouts do not have turnout road signs, but they are still acceptable to use as turnouts.  Camping, camp fires, and sleeping in vehicles are not allowed in turnouts on Highway 1.

California Vehicle Code 21656 - On a two-lane highway where passing is unsafe because of traffic in the opposite direction or other conditions, any vehicle proceeding upon the highway at a speed less than the normal speed of traffic moving in the same direction at that time, behind which five or more vehicles are formed in line, shall turn off the roadway at the nearest place designated as a turnout by signs erected by the authority having jurisdiction over the highway, or wherever sufficient area for a safe turnout exists, in order to permit the vehicles following it to proceed.

Pulling over to allow vehicles to pass when five or more vehicles are behind you is the law, but a courteous driver may pull over to allow even one vehicle to pass. 

The following are locations of paved turnouts, but consider that there are hundreds of unpaved turnouts that can be used as well.
