Monroney sticker

The Monroney sticker or window sticker is a label required in the United States to be displayed in all new automobiles and includes the listing of certain official information about the car. The window sticker was named after Almer Stillwell "Mike" Monroney, United States Senator from Oklahoma. In 1955, Senator Mike Monroney chaired a subcommittee of the Senate Interstate and Foreign Commerce Committee that investigated complaints from car dealerships in the United States about abusive treatment by manufacturers. The subcommittee continued working and investigated deceptive practices by car dealerships. Since there was no price disclosed on each car, dealers could inflate the manufacturer's suggested retail price to give the impression that buyers received a larger discount allowance or higher value for the used car they traded. There were also hidden fees and nonessential costs that were added by some dealers and consumers lacked price information, listing of options, and destination charges as they were shopping for new cars. Monroney sponsored the Automobile Information Disclosure Act of 1958, which mandated the disclosure of information about the car, its equipment, and pricing for all new automobiles sold in the United States. The act does not apply to vehicles with a gross vehicle weight rating (GVWR) of more than . Since the mid-1970s the United States Environmental Protection Agency provides fuel economy metrics in the label to help consumers choose more fuel-efficient vehicles. New requirements for the Monroney label were issued starting with 2008 model year cars and light-duty trucks sold in the US. This was included in the 2007 Energy Independence and Security Act (EISA) that mandated inclusion of additional information about fuel efficiency as well as ratings on each vehicle's greenhouse gas emissions and other air pollutants. A more comprehensive fuel economy and environment label was mandatory beginning in model year 2013, though some carmakers voluntarily adopted it for 2012.
