CTR Requirements



Bus, bike and vanpool are fun and relaxing alternatives to driving alone.

What Does the Law Say?

The Commute Trip Reduction Law is a Washington State law, first passed in 1991. Read the goals and intended outcomes of the law here. As a CTR-affected jurisdiction, the City of Seattle has adopted a CTR ordinance into its Municipal Code. Read it in full here

Drive Alone Reduction Goals
We have drive alone rate goals for all areas of Seattle. Find out what goal you are working to here. Employer drive alone rates are calculated by taking the total number of drive trips and dividing them by the total trips made to their location.

Reporting & Surveying
CTR employers report progress to the City annually. Employers file program element reports on even years  and conduct an employee commute habit survey on odd years. To find out more about your upcoming survey requirements, or recent results, please contact us.

Basic Requirements for Employers: An employer with 100 or more employees who report to work at a single site between 6 and 9 a.m. is subject to the law and must:

  • Appoint and maintain an individual to act as an Employee Transportation Coordinator (ETC) to be the primary contact between the employer and the City and to administer and promote the employer's CTR program.
  • Develop and promote a program that helps employees reduce drive-alone commute trips.
  • Submit a program report to the City for review and approval once every two years.
  • Exercise a good faith effort by collaborating with the City in its administration and implementation of the law.
  • Conduct a commuter survey once every two years to measure employees' drive alone rates.

Employer Program Requirements: Employer programs must include the following:

  • Contact information for the ETC displayed prominently at each worksite.
  • Distribute CTR Program information to employees at least twice a year and to each new employee when the new hire begins employment.
  • Program Elements – An employer's program must contain at least two of the following:
    • Bicycle parking racks and/or lockers, changing areas and showers for employees who walk or bicycle to work
    • Ride-matching services to facilitate employee carpooling and vanpooling
    • Subsidies for public transit fares
    • Vanpool vehicles
    • Subsidies for carpool and vanpool participation
    • Use of employer-owned vehicles for carpool and/or vanpool commute trips
    • Alternative work schedules, such as a compressed workweek, that reduce the number of commute trips between 6:00 and 9:00 a.m. by enabling a full-time employee to eliminate at least one (1) workday every two (2) weeks
    • Flexible work schedules that allow employees to adjust their arrival and departure times in order to accommodate transit, car-pool and van-pool schedules
    • Preferential parking for high-occupancy vehicles
    • Free or reduced parking charges for high-occupancy vehicles
    • Custom bus service to the work site
    • Special loading and unloading facilities for transit, carpool and/or vanpool users
    • Rewards and incentives for employees who do not use parking facilities
    • Institute or increase parking charges for single occupant vehicle commutes
    • Telecommute arrangements so employees can eliminate a commute trip by working from home or at a work center closer to home
    • A shuttle or circulator service between the worksite and nearby park-and-ride facilities or transit centers
    • Attend at least four meetings of a local transportation management association, transportation management organization, or employer transportation network group each year
    • Other programs or facilities that have demonstrated effectiveness at reducing vehicle miles traveled or drive-alone commutes
