Mandatory Seatbelts According to the U.S. Department of Transportation, in July 1984, New York State passed the first mandatory seatbelt law in the nation, followed by New Jersey, Illinois, Missouri, Michigan, and New Mexico.
From 1960 to 1963 sales nearly quadrupled. All auto companies offered seat belts as optional equipment at minimal cost â from about $17 to $22. Gas stations were in the business of installing belts at a charge of $6 per belt, and sales were brisk. Whereas in the mid-fifties there were eight belt manufacturers, by 1963 their numbers swelled to more than eighty.
