Carline [Transportation] Law and Legal Definition

According to 49 CFR 583.4 [Title 49 – Transportation; Subtitle B -- Other Regulations Relating to Transportation; Chapter V -- National Highway Traffic Safety Administration, Department of Transportation; Part 583 -- Automobile Parts Content Labeling], carline means “a name denoting a group of vehicles which has a degree of commonality in construction (e.g., body, chassis). Carline does not consider any level of decor or opulence and is not generally distinguished by such characteristics as roof line, number of doors, seats, or windows, except for light duty trucks. Carline is not distinguished by country of manufacture, final assembly point, engine type, or driveline. Light duty trucks are considered to be different carlines than passenger cars. A carline includes all motor vehicles of a given nameplate. Special purpose vehicles, vans, and pickup trucks are classified as separate carlines.”
