Lacey, WA Mobility & Curb Rules: Bike Lane Rules (2026)

Section 10.10.150 has three rules. First, every person operating a bicycle upon a roadway must ride as near to the right side as practicable, exercising due care when passing a standing vehicle or one proceeding in the same direction. Second, riders on a roadway cannot ride more than two abreast, except on paths set aside for the exclusive use of bicycles. Third, whenever a usable path for bicycles has been provided adjacent to a roadway, riders must use the path and cannot use the roadway. The third rule is mandatory, not a preference.

The chapter's reach is set in § 10.10.020: it applies whenever a bicycle is operated on any street, sidewalk or public path set aside for the exclusive use of bicycles, and a parent or guardian cannot authorize or knowingly permit a child or ward to violate it. Under § 10.10.120, a person riding on a roadway has the rights and duties of a vehicle driver, and § 10.10.130 requires obedience to traffic-control signals and signs, including no-turn signs unless the rider dismounts and follows pedestrian rules.

Related sections fill in the rest. Parking under § 10.10.200 is on the roadway against the curb, on the sidewalk in a rack, or against a building, or at the curb in a way that affords the least obstruction to pedestrian traffic. Under § 10.10.210 the chief of police can post signs prohibiting bicycle riding on a sidewalk or roadway, and a rider on a sidewalk must yield to any pedestrian and give an audible signal before overtaking. Section 10.10.220 requires, from thirty minutes after sundown until daylight, a front lamp visible from at least five hundred feet and a red rear reflector, and every bicycle needs a brake that locks the rear wheel. This chapter regulates riders; it prints no separate rule on drivers blocking a bike lane.
