Passing zones may be for northbound traffic only (broken centerline in northbound lane and solid centerline in southbound lane), southbound traffic only (broken centerline in southbound lane and solid centerline in northbound lane), or traffic in both directions (a single broken centerline).  Passing zones are scarce on Highway 1.  If traffic wishes to pass you, don't speed up.

Consider using a turnout - when it is safe to do so - whenever traffic backs up behind you.  

MM = mile marker, roadside markers along Highway 1 in Monterey County that indicate the number of miles north of the border between Monterey and San Luis Obispo counties.
