The Commute Trip Reduction Law   Is the Law working? (external link)   Is Your Company Affected by the CTR Law?   Summary of CTR Requirements   CTR Forms

The state Commute Trip Reduction (CTR) law (external link) was introduced as part of the Washington State Clean Air Act in 1991 to get government, businesses and individuals working together to begin reducing vehicle trips. Local jurisdictions then implemented ordinances to define how the law would apply to worksites in their area. The state law and local ordinances were revised in 1997.

The purpose of the CTR Law is to reduce air pollution, traffic congestion and fuel consumption by encouraging commuters to bus, carpool, vanpool, bicycle, walk, or work compressed work weeks or flexible work schedules instead of driving alone to work everyday. The law requires major employers to provide employee transportation programs to encourage this shift.
