Washington State law requires studded tires be removed by midnight Thursday, March 31st. Driving with studded tires after March 31st is a traffic infraction that could result in a $136 ticket.
The Washington law applies to all drivers in the state, even visitors. No personal exemptions or waivers are issued.
Drivers are advised to schedule early with tire removal businesses as they become more crowded as the deadline approaches.
More details regarding studded tires and other Washington State vehicle and equipment requirements are available on the Washington State Patrol website.
