Show or Display

The "Show or Display" rule is a statutory amendment to the United States Federal Motor Vehicle Safety Standards (FMVSS) that allows certain privately imported automobiles to be exempted, if the vehicle in question is deemed to meet a standard of "historical or technological significance".

The amendment, which became law on August 13, 1999, is intended to apply to vehicles that could not feasibly be brought into compliance with the FMVSS, including requirements for destructive testing – and that do not have a similar make or model certified for sale in the United States market. Applications are managed by the National Highway Traffic Safety Administration, and may allow limited use on public roads (2,500 miles (4,000 km) annually).

The permitted vehicle list is mostly restricted to expensive sports and touring automobiles due to the cost and effort needed to import a vehicle with this exemption.
