Speed Limits

To request a speed limit revision in your area, you will need to complete a service request. Once the form is submitted, staff will reach out to you for more details. The Board of County Commissioners makes the final decision to change the speed limit. 

Speed limits in school zones and residential areas are set by county code and cannot be changed.

Speed Limit revisions are presented yearly to the Board of County Commissioners (BoCC) for consideration and adoption. Any potential revisions received after March 31 will be held until the next calendar year for presentation to the BoCC. 

Pursuant to RCW 46.09.455, the Board of County Commissioners passed an ordinance allowing wheeled ATVs to travel on county roads with a maximum speed limit of 35 MPH by licensed drivers over the age of 16.
