Washington State Department of Transportation announcement.
The arrival of spring brings a reminder to drivers in Washington to remove studded tires before the end of the day Thursday, March 31. By planning ahead, drivers can beat the rush at tire service shops and avoid a potential fine of $136, starting Friday, April 1.
Studded tires are legal in Washington from Nov. 1 to March 31. The Washington State Department of Transportation encourages drivers to remove studded tires prior to the deadline, if possible. Studded tires damage pavement, so removing them promptly after winter has passed helps preserve state roadways.
State law gives WSDOT the authority to extend the deadline when circumstances call for it, most commonly when a forecast indicates widespread snow and ice. While late season storms are possible in the mountain passes, there are no forecasted statewide conditions that would call for an extension of the deadline. For mountain travel, WSDOT recommends drivers use approved traction tires and carry chains, if necessary.
Travelers are always advised to “know before you go” by checking road conditions before heading out and staying up-to-date on changes by using WSDOT’s social media and email alert tools or calling the 5-1-1 road conditions report.
Washington and Oregon share the same studded tire removal deadline. Other states may have different studded tire removal dates, but the Washington law applies to all drivers in the state, even visitors. No personal exemptions or waivers are issued.
