What to do with Colorado plates after moving to Montana
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Colorado instruction only after the Montana registration and insurance handoff are safe.
Complete the replacement record
Title and register the vehicle through the county treasurer within 60 days after establishing Montana residency.
Carry proof of Montana-compliant insurance while driving. Montana MVD says proof is not required to complete the registration transaction, but coverage remains required for operation.
Return or recycle Colorado plates after replacement registration
After the destination registration is active and the Colorado plates are off the vehicle, return regular plates to a Colorado county motor vehicle office or use a recycler that accepts metal license plates. Ask the county before disposing of personalized or qualifying specialty plates, and retain the replacement registration proof.
