Gives plain meanings for words used in this part. Manufacturer (as used in sections 7521, 7522, 7525, 7541, and 7542) means a person who makes, assembles, or imports new motor vehicles or new motor vehicle engines for resale, or who acts for and is controlled by such a person in distributing them; it does not include a dealer for vehicles the dealer receives in commerce. Motor vehicle means a self-powered vehicle made to carry people or goods on streets or highways. New motor vehicle and new motor vehicle engine mean ones whose legal or equitable title has never been transferred to the first buyer; for imports, they are those made after the effective date of a regulation under section 7521 that applies (or would apply) to them. Dealer means someone who sells or distributes new vehicles or engines to the first buyer. Ultimate purchaser means the first person who in good faith buys a new vehicle or engine for use, not for resale. Commerce means trade that crosses state lines or any trade entirely inside the District of Columbia. The terms vehicle curb weight, GVWR, LDT, light-duty vehicle, and LVW mean what the Administrator’s regulations said on November 15, 1990, and the abbreviations match those terms. Test weight (tw) means vehicle curb weight plus GVWR, divided by 2. Motor vehicle or engine part manufacturer means a person who makes, assembles, or rebuilds parts or components installed in vehicles or engines. Nonroad engine means an internal combustion engine (including its fuel system) that is not used in a motor vehicle or in a vehicle used only for competition, or that is not covered by standards under section 7411 or section 7521. Nonroad vehicle means a vehicle powered by a nonroad engine that is not a motor vehicle and not a competition-only vehicle.
