The Monroney label is the federally required window sticker on every new car sold in the United States. It tells you, before any negotiation, what the manufacturer charges for the vehicle, how it performed in government crash tests, what mileage the EPA expects it to get, and where its parts and assembly come from. Federal law dictates what appears on it, where it goes, and who is allowed to touch it.
What Federal Law Requires on the Label
The core disclosures come from 15 U.S.C. § 1232. Every label must show the make, model, and serial or identification number of the vehicle; the final assembly point; the name and business location of the dealer receiving it; the city or town where it will be delivered; and the method used to move it from the factory to the dealership if it was driven or towed.1Office of the Law Revision Counsel. 15 USC 1232 Label and Entry Requirements
A common misconception: the statute does not require detailed mechanical specs like engine displacement or transmission type. Those often appear because manufacturers add them voluntarily or because other rules (such as EPA fuel economy labeling) reference powertrain characteristics. Section 1232 itself is about identity, origin, and price.
How the Pricing Section Breaks Down
The financial block is where most buyers look, and the statute lists four specific line items:
- The manufacturer’s suggested retail price for the base vehicle.
- The individual price of every factory-installed accessory or optional feature physically on the car at delivery.
- The destination charge for transporting the vehicle from the factory to the dealership.
- The total of the three figures above.1Office of the Law Revision Counsel. 15 USC 1232 Label and Entry Requirements
That total is the MSRP quoted in advertising. It is a suggestion. Dealers can sell above or below it. Because the label itemizes each component, you can see exactly what you’re paying for the base car, the options, and shipping. Dealer-added charges such as documentation fees, paint protection packages, or market-adjustment markups are never part of the Monroney label and are never included in its MSRP figure.2Maine.gov.

Safety Ratings
A 2007 amendment added crash-test disclosures to § 1232. If NHTSA has tested the vehicle under its New Car Assessment Program, the label must display the star ratings using a graphic that shows the maximum possible score next to the vehicle’s actual score. Rating categories can include frontal crash, side crash, and rollover resistance. The label must explain what the ratings mean and direct buyers to safercar.gov.1Office of the Law Revision Counsel. 15 USC 1232 Label and Entry Requirements
NHTSA’s implementing regulation at 49 CFR 575.302 specifies a five-star scale, with five stars the best outcome and one star the worst. If a vehicle has not been rated in a given category, the label cannot simply leave it blank. It must carry the statement: “This vehicle has not been rated by the government for overall vehicle score, frontal crash, side crash, or rollover risk.”3eCFR. 49 CFR 575.302 Vehicle Labeling of Safety Rating Information
Fuel Economy and Environmental Data
The EPA requires a separate fuel economy and environment graphic on every new vehicle. For gasoline and diesel vehicles, it shows miles-per-gallon ratings for city, highway, and combined driving. It estimates annual fuel cost and compares five-year fuel spending against the average new vehicle, stating either “You save” or “You spend” a specific dollar amount. Those calculations assume 15,000 miles per year at fuel prices projected by the U.S. Energy Information Administration.4eCFR. 40 CFR Part 600 Subpart D Fuel Economy Labeling5U.S. Environmental Protection Agency. Text Version of the Gasoline Label
Two slider bars on a 1-to-10 scale show how the vehicle compares to all other new vehicles for greenhouse gas emissions and smog-forming pollutants. Ten is the cleanest. Those scores let you compare environmental impact across very different vehicle types at a glance.4eCFR. 40 CFR Part 600 Subpart D Fuel Economy Labeling
Electric and Plug-In Hybrid Vehicles
Electric vehicles get a version of the label built around battery driving. Instead of MPG, it shows MPGe (miles per gallon equivalent), which translates electricity consumption into a figure comparable to gasoline. The label also shows energy consumption in kilowatt-hours per 100 miles, which is more useful if you think in electricity cost.4eCFR. 40 CFR Part 600 Subpart D Fuel Economy Labeling
The EV label must include a driving-range graphic, a horizontal bar showing how far the vehicle can travel on a full charge, with total range stated in miles. Below that, the label lists charge time in hours based on a 240-volt outlet. If the vehicle cannot accept 240-volt charging, the label uses the 120-volt figure instead. The label also discloses tailpipe CO₂ emissions per mile, with a note that the figure does not account for emissions from electricity generation.6U.S. Environmental Protection Agency. Text Version of the Electric Vehicle Label
Parts Content and Country of Origin
The American Automobile Labeling Act, implemented through 49 CFR Part 583, requires a parts-content disclosure. It can appear as part of the Monroney label, as part of the fuel economy label, or as its own standalone label. Wherever it sits, it must be readable from outside the vehicle with the doors closed.7eCFR. 49 CFR Part 583 Automobile Parts Content Labeling
The parts-content label must disclose the overall percentage of equipment by value originating in the United States or Canada, rounded to the nearest 5 percent. It must list any countries that are major foreign sources of parts, with their percentage contributions. The country of origin for the engine and the transmission must each be stated separately. The final assembly point is stated as a city, state, and country. If you care about domestic sourcing, the format is standardized enough that comparing two vehicles side by side is straightforward.7eCFR. 49 CFR Part 583 Automobile Parts Content Labeling
The Monroney Label vs. the Dealer Addendum
Walk a dealership lot and you’ll often see a second sticker next to the Monroney label. That is the dealer addendum, and it is a different document entirely. The Monroney label is federal and reflects the manufacturer’s pricing. The addendum is created by the dealership and lists dealer-installed accessories, services like paint protection or security systems, and sometimes a flat “market adjustment” markup. No federal law caps what a dealer can charge for anything on the addendum.
The distinction matters because the addendum can add thousands of dollars to the price. Buyers sometimes mistake the addendum total for the MSRP, or assume the listed items are required. They are not. Everything on a dealer addendum is negotiable, and you are under no obligation to pay for accessories or services the dealer added after receiving the vehicle. Only the Monroney label carries the force of federal disclosure law.
Who Can Remove the Label and What Happens If Someone Does
Federal law requires the manufacturer to attach the Monroney label to the windshield or a side window before delivering the vehicle to a dealer. It must stay in place and legible until the vehicle reaches its ultimate purchaser, meaning the person who actually buys it. No one else, including dealership staff, has the legal right to remove, alter, or obscure it. The one exception is that a manufacturer may relabel a vehicle that gets rerouted, repurchased, or reacquired.8Office of the Law Revision Counsel. 15 USC 1233 Violations and Penalties
Penalties under 15 U.S.C. § 1233 fall into three categories:
- A manufacturer that willfully ships a vehicle without a Monroney label faces a fine of up to $1,000 per vehicle.
- A manufacturer that willfully fails to fill in the label correctly, or prints false information, faces the same $1,000-per-vehicle fine.
- Anyone who willfully removes, alters, or makes the label illegible before the buyer takes possession faces a fine of up to $1,000 per vehicle, up to one year in prison, or both.
Each vehicle counts as a separate offense, so a dealership that stripped labels from a batch of cars on the lot would face cumulative fines. The prison provision applies only to tampering, not to a manufacturer’s failure to attach or fill in the label. These penalty amounts have not been adjusted since 1958, so the financial deterrent is modest. The real pressure comes from the per-vehicle multiplication and the criminal exposure for tampering.8Office of the Law Revision Counsel. 15 USC 1233 Violations and Penalties
If you’re shopping for a new car, the Monroney label is the one document on the vehicle you can trust to say the same thing at every dealership. Read it before you read anything else on the glass.
