What to do with Illinois plates after moving to Connecticut
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Illinois instruction only after the Connecticut registration and insurance handoff are safe.
Complete the replacement record
Transfer the out-of-state registration within 90 days. Connecticut allows a combined appointment when the license and vehicle transactions are both ready.
Bring proof of insurance that meets Connecticut's minimum requirements for the registration transaction.
Revoke the Illinois plate record after the replacement registration is active
After the destination registration is active, submit VSD 851, Vehicle License Plates Revocation Request, using the registered-owner-moved-out-of-state reason. Keep a copy and delivery proof before treating the old insurance record as closed.
