§ 86.1802-01 Section numbering; construction.

(a) Section numbering. The model year of initial applicability is indicated by the section number. The two digits following the hyphen designate the first model year for which a section is applicable. The section continues to apply to subsequent model years unless a later model year section is adopted. Example: Section 86.18xx–10 applies to model year 2010 and later vehicles. If a § 86.18xx–17 is promulgated, it would apply beginning with the 2017 model year; § 86.18xx–10 would apply only to model years 2010 through 2016, except as specified in § 86.18xx–17.
