Welcome! Thurston Commutes is your Commute Trip Reduction (CTR) resource center. CTR is a Washington State Law about encouraging workers to drive alone less, reduce carbon emissions, and keep the busiest commute routes flowing.
Who is Required to participate?
- Employers who have 100+ employees at a single worksite who:
- Arrive between 6-9am, 2+ weekdays, for 12 continuous months of the year
- Full time: scheduled 35+ hours per week
Are you affected by the CTR law? We're here to help you navigate the rules and implement a program that works for your specific worksite!
