Commute Trip Reduction (CTR)

What Is CTR?

Washington’s Commute Trip Reduction (CTR) law (RCW 70.94.521) was adopted by the State Legislature in 1991. The goal of Washington’s CTR program is to:

  • Reduce traffic congestion
  • Improve air quality
  • Minimize energy consumption

Employers with 100 or more employees arriving at a worksite between 6 and 9 a.m. year-round are identified as major employers under the CTR law and are required to participate in the CTR program. 

Contact Information

For more information or to see if your worksite is affected call 425-257-8727.

Do you represent an employer not affected by this CTR law, but are affected by congestion in Everett? Are you interested in helping your employees find carpools or vanpools to and from work? Call 425-257-8727 to learn how you can participate.
