Seattle Speed Limits and Right-of-Way Rules

Transportation Washington 4 Minutes Read · published February 07, 2026 Flag of Washington

Seattle, Washington drivers, cyclists and pedestrians must follow city speed limits and right-of-way rules set by the Seattle Municipal Code and administered by the Seattle Department of Transportation (SDOT) and enforced by Seattle Police Department (SPD). This guide explains where authority comes from, how limits and priority are posted and enforced, how to request changes, and what to do after a ticket or safety concern. It focuses on city processes and links to official sources so you can act or appeal with the correct agency.

How Seattle sets speed limits and right-of-way

The city adopts speed limits and traffic-control orders through municipal code and administrative actions; SDOT operates speed zone studies, posts limits and updates signage, while legal authority and code language appear in the Seattle Municipal Code. For official speed listings and program details, see the SDOT speed limits program page Seattle DOT Speed Limits[1]. For the municipal code provisions governing vehicles and traffic, see Seattle Municipal Code Title 11 SMC Title 11[2].

Watch for posted signs—legal limits are those posted or adopted by ordinance.

Right-of-way basics

Right-of-way rules assign priority between motorists, pedestrians and cyclists at intersections, crosswalks and when entering roadways. Drivers must yield where signs or pavement markings indicate and at marked crosswalks; pedestrians have legal protections at crosswalks and at intersections under city and state law. For enforcement and reporting of unsafe conditions, contact SPD traffic safety resources SPD Traffic Safety[3].

Penalties & Enforcement

Enforcement for speed and right-of-way violations is typically by citation through Seattle Police Department or traffic camera programs where authorized; civil or criminal penalties depend on the specific violation and statute cited. Specific fine amounts are not consistently listed on the cited city program pages and are often set by municipal fine schedules or state law; fine amounts are not specified on the cited pages.[2]

  • Monetary fines: exact amounts not specified on the cited city pages; see the municipal code or court schedule for the charged infraction.
  • Court action: certain violations may require a court appearance; court procedures and calendars are handled by the municipal or district court (not specified on the cited page).
  • Administrative actions: orders to correct signage or road conditions are issued by SDOT; removal or correction of hazards may be enforced administratively.
  • Complaints and inspections: report unsafe speeds, signage or right-of-way issues to SDOT or SPD via their official contact pages.
Traffic cameras and citations follow city program rules and state authorization.

Applications & Forms

To request a speed study, sign change or traffic-calming measure, SDOT provides request processes on its official site; specific form names or numbers are not published on the general program page and may be handled through online request portals or email to SDOT operations (see SDOT link). If no formal form is required, the city accepts requests via the designated SDOT online request tool or contact email as listed on SDOT pages.[1]
