Essential parts: all integral and body parts of a vehicle of a type required to be registered hereunder, the removal, alteration, or substitution of which would tend to conceal the identity of the vehicle or substantially alter its appearance, model, type, or mode of operation.
Reconstructed vehicle: every vehicle of a type required to be registered hereunder materially altered from its original construction by the removal, addition, or substitution of essential parts, new or used.
Specially constructed vehicle: every vehicle of a type required to be registered hereunder not originally constructed under a distinctive name, make, model, or type by a generally recognized manufacturer of vehicles and not materially altered from its original construction.
Antique motor vehicle: a motor vehicle over twenty-five (25) years old with a nonmodified engine and body which is used for participation in club activities, exhibits, tours, parades, and similar uses as a collector's item, but is in no event used for general transportation.
Tennessee Antiques: SAN-supported legislation to allow for "general transportation purposes" on Saturdays and Sundays for registered antique motor vehicles was signed into law. Under the previous law, use of antique vehicles was strictly limited to "club activities, exhibits, tours, parades, and similar uses as a collector's item."
Kit Car: a motor vehicle which does not utilize a chassis from a vehicle certified to meet emissions control standards or for which the original manufacturer's identification has been eliminated due to the replacement of the vehicle's body with one of a different make and/or style.
Street Rod: any modified antique automobile manufactured prior to 1949.
Tennessee Custom Vehicles: SAN legislation to create a vehicle registration and titling classification for custom vehicles was passed by the Tennessee Senate and was pending House consideration when the legislature adjourned. The measure defined a custom as an altered vehicle over 25 years old or manufactured to resemble a vehicle 25 years old or older. Under the bill, kit cars and replica vehicles would have been assigned a certificate of title bearing the same model year designation as the production vehicle it most closely resembles. The bill exempted customs from periodic vehicle inspections and emissions inspections and from a range of standard equipment requirements. The legislation also provided for a one-time registration fee of $25, valid as long as you own the custom vehicle. SAN is working with legislators to have the bill reintroduced in 2007.
Tennessee Nitrous Oxide: The Tennessee Legislature withdrew legislation to prohibit the highway use of a vehicle equipped to supply nitrous oxide to the engine unless the system is made inoperative by disconnecting the line feeding nitrous oxide; removing the containers from the vehicle; or turning the tank to the off position. The bill did not prohibit operating a tow vehicle or RV that is equipped to supply the engine with nitrous. The bill is based on SAN-model legislation offered to state legislators as a compromise to a complete ban on nitrous oxide systems.
