Riverside, CA Parking Rules: Curb Color Rules (2026)

Colored curb markings in the unincorporated county are established by County Ordinance 413, which assigns authority and meaning to each color. The Director of Transportation posts signs or causes curbs to be painted to give notice of parking restrictions (Sections 1.5 and 1.11), and may establish restricted or no-stopping zones only after an engineering study and field review. The official curb colors and meanings come from Section 1.9: Red means no stopping, standing or parking at any time, except a bus may load in a marked red bus zone and a posted taxi zone is for taxicabs only; Yellow means no parking 7 a.m. to 6 p.m. except Sundays and holidays other than for loading (five minutes for passengers, twenty for materials); White means stopping only to load passengers or deposit and collect mail at an adjacent mailbox; and Green means parking for the time limit posted by signs or curb-top stencils. Section 1.14 adds Blue: disabled-parking spaces designated by the Board of Supervisors are indicated by blue paint on the curb or pavement edge, and parking there without a valid placard or plate is prohibited. Section 1.7 uses white lines (not curb color) to mark angle-parking stalls. Because curb marking is a function delegated to the Director of Transportation, residents may not paint public curbs themselves to create or change parking rules.
