(a) 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 effective. A section is effective until superseded.
Example: Section 600.111-78 applies to the 1978 and subsequent model years until superseded. If a § 600.111-81 is promulgated, it would take effect beginning with the 1981 model year; § 600.111-78 would apply to model years 1978 through 1980.
(b) A section reference without a model year suffix refers to the section applicable for the appropriate model year.
