Maryland “Show Class” Vehicles: Maryland has introduced legislation to create a new “show class vehicle” registration classification. Under the bill, “show class” is defined as a vehicle that has decorative features or alterations and is used primarily for transportation to and from shows, repair facilities, parades, holiday or weekend activities or similar uses. These vehicles would be limited to 5,000 miles per year, but would be exempt from specific equipment requirements and the use and inspection of emissions controls.
