What matters now
- The safety rating label is a mandatory part of the Monroney label, the same label that carries a new car's price and consumer information.
- The stars are not the manufacturer's own claim; they must come from NHTSA's own vehicle testing program.
- The requirement applies to model year 2012 and later vehicles manufactured on or after January 31, 2012.
- This is a labeling requirement for new vehicles only, not a ranking or comparison tool.
Yes. The star rating on a new car’s window sticker is a government-created safety rating, and federal regulation requires manufacturers to display it. That requirement comes from 49 CFR §575.302, titled “§ 575.302 Vehicle labeling of safety rating information (compliance required for model year 2012 and later vehicles manufactured on or after January 31, 2012)” (eCFR §575.302).

Key points
- The safety rating label is a mandatory part of the Monroney label, the same label that carries a new car’s price and consumer information.
- The stars themselves are not the manufacturer’s own claim; they must come from NHTSA’s own vehicle testing program.
- The requirement is dated: it applies to model year 2012 and later vehicles manufactured on or after January 31, 2012.
- This is a labeling requirement for new vehicles only, not a ranking or comparison tool this article evaluates.
Monroney safety rating label
The regulation defines the Monroney label as “the label placed on new automobiles with the manufacturer’s suggested retail price and other consumer information, as specified at 15 U.S.C. 1231-1233” (eCFR §575.302). The safety rating label is not a separate, optional sticker — it is built into that same required consumer-information label.
Rating-term definition
49 CFR §575.302 defines the term directly: “Safety rating label means the label with NCAP safety rating information, as specified at 15 U.S.C. 1232(g). The safety rating label is part of the Monroney label” (eCFR §575.302). In other words, the authority to require this specific label traces to a named federal statute, not to a manufacturer’s own choice or a private ratings organization.
NHTSA testing source
The regulation also fixes where the star score has to originate: “the ratings placed on the safety rating label are derived from vehicle testing conducted by the National Highway Traffic Safety Administration under the enhanced NCAP testing and rating program” (eCFR §575.302). A manufacturer cannot substitute its own crash-test results or a third-party score for the government-run figure on this part of the label.
When this requirement took effect
The rule’s title states its own effective scope: compliance is required “for model year 2012 and later vehicles manufactured on or after January 31, 2012” (eCFR §575.302).
What this article does not answer
This article settles only whether the star rating is a required, government-sourced label on new-car window stickers — nothing more. It does not explain how NHTSA calculates or weights that star score, including its crash-test methodology or scoring formula. It does not address whether a higher-rated vehicle is actually safer for any particular reader or use case. It does not cover used-car window stickers or any labeling requirement that applies after the first retail sale. And it offers no purchase, shopping, or comparison advice between makes or models.
