Federal rules vs. South Dakota
Federal import rule
Federal law decides whether a Kei vehicle can enter the U.S. at all. Vehicles at least 25 years old are generally exempt from FMVSS import requirements under the federal 25-year rule, which is what makes most classic JDM Kei trucks importable. This is the same nationwide, regardless of state.
How importing worksSouth Dakota's decision
Once imported, each state decides independently whether the vehicle can be titled, registered, and driven on public roads. That is where South Dakota currently lands:
