Shasta County, CA Parking Rules: Curb Color Rules (2026)

Shasta County does not have its own curb-color ordinance; it relies on the uniform statewide meanings in California Vehicle Code Section 21458. Under that section, where local authorities cause curb markings to be painted: a red curb means no stopping, standing, or parking whether the vehicle is attended or not (with a bus-zone exception); a yellow curb means stopping only to load or unload passengers or freight; a white curb means stopping only to load or unload passengers or to deposit mail in an adjacent mailbox; a green curb means time-limit parking as specified by local ordinance; and a blue curb means parking limited to vehicles of disabled persons and disabled veterans displaying the proper placard or plates. These colors are enforceable only where painted by the road authority. Curb markings on county-maintained roads are an official traffic-control measure installed by Shasta County Public Works, and any local time limit tied to a green curb must rest on an underlying county ordinance and posted notice consistent with CVC Section 22507. Unauthorized painting, stenciling (for example, painting a house number or a private 'no parking' message), or altering of a public curb is not permitted, because it interferes with official traffic-control markings.
