King County's Regional Trails System and the 2018 Strategic Plan for Road Services govern bike lanes, separated cycle tracks, and shared-use paths across unincorporated roads, with cities adopting similar Complete Streets policies.
King County Roads Services applies the Complete Streets ordinance and Regional Trails Plan when designing or rebuilding county roads, prioritizing protected bike lanes near schools, transit, and trail crossings. The Eastrail, Burke-Gilman Trail, and Green-to-Cedar River Trail anchor the regional network and connect Seattle, Bellevue, Redmond, and unincorporated areas. State rules in RCW 46.61.755 give bicyclists road rights and responsibilities, while local code forbids motor vehicles in marked bike lanes except for crossings and parking maneuvers.
Driving, parking, or stopping in a marked bike lane outside lawful turning movements is a traffic infraction under state and local code, with fines starting around $136 and escalating in school zones.
