What is Commute Trip Reduction (CTR)?
Washington’s CTR law (RCW 7094.521) was adopted by the legislature in 1991 and incorporated into the Washington Clean Air Act. Its purpose is to improve air quality, reduce traffic congestion, and minimize energy consumption by convincing people to other ways to get to work besides driving alone. The law requires the state’s largest employers to promote commute alternatives such as buses, carpools, vanpools, bicycle riding, walking, working from home, compressed work weeks, and flexible work schedules.
