Financial Channel

A co-worker was driving a Wisconsin-registered vehicle in Minnesota. He was self-insured in accordance with Wisconsin's "financial responsibility" law. He was pulled over and cited for not having insurance in Minnesota. Does he have a valid argument that since he was in full compliance with Wisconsin vehicle registration and operating laws, Minnesota should give full faith and credit and allow him to operate across the border?

States don't have to let uninsured vehicles operate on their roads under "full faith and credit", even if that is permitted (under any rubric, including being "self-insured") in other states. But... most states do have statutory provisions which exclude from "uninsured driving" laws the operation of a vehicle that is properly insured under the state in which it is licensed. Further, there may issues under the Interstate Commerce Clause of the Constitution which would render a ticket of the type you describe unenforceable.
