Unless DOT grants a weather-related extension, studded tires are only legal in Washington from Nov. 1 to March 31. No extension is planned.
Crews will keep an eye on forecasts, especially at higher elevations, and will be ready to treat and clear roadways if wintry weather returns.
Under state law, driving with studded tires after March 31 is a traffic infraction and could result in a $124 ticket.
