Program Requirements

The Washington State Commute Trip Reduction (CTR) Efficiency Act (ESSB 6566) applies to all public (i.e. federal, state and local governments, and military) and private employers located within the affected urban growth areas that have 100 or more employees reporting to work at a single work site between 6-9am on at least two weekdays each week. A company may have more than one affected worksite, or may have some worksites that are affected and some that are not.

The Commute Trip Reduction law also applies to local jurisdictions (cities and counties) where an affected employer is located, regardless of the number of affected employee at the jurisdiction worksite.

The state law requires employers that meet the definition of “affected employer” to identify themselves to the local city/county within 180 days of either: moving into the boundaries of the jurisdiction; or growing in employment to 100 or more employees (or the employee threshold defined with the local CTR Ordinance).



Is your company effected by the commute trip reduction act?

If you think your company may be affected by the CTR law, please call the CTR office at 360-487-7733 or e-mail CTR Administrator.

 The Washington Commute Trip Reduction law and local CTR ordinances state that an affected employer must make a good faith effort to develop and implement a Commute Trip Reduction program designed to reduce the number and length of drive-alone commute trips made to the worksite.

This means at a minimum, employers are required to do the following:

  • Designate an Employee Transportation Coordinator (ETC).
  • Display the ETC’s name and contact information in a prominent location.
  • Distribute information to employees about commute alternatives to driving alone.
  • Implement a set of measures geared toward achieving the CTR goals.
  • Measure employee commute behavior every two years.
  • Report annually about progress toward meeting CTR goals.
