StuddedTires-tThe Washington State Department of Transportation (WSDOT) reminds drivers to remove their studded tires by midnight Monday (March 31). Unless WSDOT grants a weather-related extension, studded tires are only legal in Washington from Nov. 1 to March 31. With forecasts the rest of the month calling for temperatures well above freezing in most parts of the state, WSDOT does not plan to extend the deadline. Under state law, driving with studded tires after March 31 is a traffic infraction and could result in a $124 ticket.
