What to do with Idaho plates after moving to Utah
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Idaho instruction only after the Utah registration and insurance handoff are safe.
Complete the replacement record
Register the vehicle in Utah within 60 days after meeting a listed residency trigger, including establishing a permanent home, accepting nonseasonal work, or obtaining a Utah license.
Maintain required motor-vehicle liability coverage before operating and registering the vehicle in Utah.
Cancel the Idaho plate record before dropping its insurance support
After the destination registration is active, submit Idaho's ITD 3438 License Plate Cancellation Request with the moved-out-of-state reason and choose whether to cancel the plate, registration, or both. Keep the submitted form and delivery confirmation before ending the policy that supported the Idaho record.
