§ 86.601-84 Applicability.

The provisions of this subpart apply to light-duty vehicles, light-duty trucks, and heavy-duty vehicles. However, manufacturers that optionally certify heavy-duty vehicles based on chassis testing under § 86.1863–07 may choose instead to perform selective enforcement audits using the procedures specified in 40 CFR part 1068, subpart E. References to “light-duty vehicle” or “LDT” in this subpart G shall be deemed to include light-duty trucks and heavy-duty vehicles as appropriate.
