§ 1037.5 Excluded vehicles.
Except for the definitions specified in § 1037.801, this part does not apply to the following vehicles:
(a) Vehicles not meeting the definition of “motor vehicle” in § 1037.801.
(b) Vehicles excluded from the definition of “heavy-duty vehicle” in § 1037.801 because of vehicle weight, weight rating, and frontal area (such as light-duty vehicles and light-duty trucks).
(c) Vehicles produced in model years before 2014, unless they were certified under § 1037.150.
(d) Medium-duty passenger vehicles and other vehicles subject to the light-duty greenhouse gas standards of 40 CFR part 86. See 40 CFR 86.1818 for greenhouse gas standards that apply for these vehicles. An example of such a vehicle would be a vehicle meeting the definition of “heavy-duty vehicle” in § 1037.801 and 40 CFR 86.1803, but also meeting the definition of “light truck” in 40 CFR 86.1818-12(b)(2).
