What to do with Washington plates after moving to South Dakota
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Washington instruction only after the South Dakota registration and insurance handoff are safe.
Complete the replacement record
Title and register the vehicle through the county treasurer within 90 days after arriving in South Dakota.
Maintain the financial responsibility required to operate in South Dakota and keep the prior policy active until the old registration is safely closed.
Invalidate or return old Washington plates
After the destination registration is active, remove or invalidate the Washington month and year tabs and bend regular plates so they cannot be mistaken for valid plates. Recycle them where accepted or mail or take them to a vehicle licensing office. Washington requires listed personalized, disabled, collector, and other special plates to be returned rather than recycled.
