Orange County and OCTA maintain a multi-jurisdictional bike network using California Vehicle Code Class I, II, III, and IV designations across regional trails, on-street lanes, and signed bike routes.
California Streets and Highways Code 890.4 defines bike facilities: Class I separated paths like the Santa Ana River Trail and San Diego Creek Trail, Class II striped on-street lanes, Class III signed routes shared with vehicles, and Class IV protected separated bikeways. OCTA's Commuter Bikeways Strategic Plan funds segments connecting cities, with construction by individual cities or county. Riders must use the right-most lane, signal turns, and obey traffic laws. Sidewalk riding rules vary by city, and CVC 21202 requires riders below the speed of traffic to ride as far right as practicable except when avoiding hazards.
Cycling violations carry CVC fines similar to vehicle infractions, often $200-plus. Building unauthorized bike lanes or removing markings is a public-works violation.
