Full Breakdown
' The ban applies whenever a lane is marked, not just during posted hours, and covers any vehicle left there, not only unattended cars. 25 treats a bicycle as a vehicle for the rules of the road. 040: it is unlawful in a business district or on any street with a designated bicycle path, though sidewalk riding is allowed in exclusively residential areas unless the sidewalk itself is posted against it, and a cyclist on a sidewalk must yield to pedestrians. 060 lets the issuing agency divert a first-time bicycle-rule violator into a safety program instead of court, when one is available. 12.
Violations & Fines
Blocking a bike lane under § 12.20.030 is an infraction under the citywide penalty scheme, fined per the City Council's Bail Schedule, escalating to a misdemeanor on a fourth citation for the same offense within a year. A cyclist cited under Chapter 12.25 for a riding violation, such as illegal sidewalk riding or failing to obey a traffic signal, can instead be offered a bicycle safety program at the issuing officer's discretion under § 12.25.060.
