Full Breakdown
County Code § 18-3.3(d) lets Sonoma Public Infrastructure establish loading zones, passenger loading zones, and bus loading zones on county roads. A vehicle in a loading zone may only load or unload passengers or freight, capped at 20 minutes; a passenger loading zone caps standing at 5 minutes; bus loading zones are reserved for commercial or school buses only. Unless a sign specifies otherwise, these limits apply from 9:00 a.m. to 6:00 p.m., holidays excepted, a theatre-front passenger zone instead runs whenever the theatre is open. This governs unincorporated county roads only; Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sebastopol, Cotati, Cloverdale and the City of Sonoma each set their own loading-zone rules under their own codes.
Violations & Fines
Overstaying a posted loading zone violates County Code § 18-3.4(b) and is punishable as a parking penalty set by Board of Supervisors resolution under Vehicle Code § 40200 et seq.; a vehicle left standing in violation is subject to citation and removal to a garage or other place of safety.
