Sec. 600.004-77  Section numbering, construction.

    (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until superseded.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years until superseded.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 Sec. 600.111-81 is promulgated, it would 
take effect beginning with the 1981 model year; Sec. 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.
