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.
The push for mandatory seat belt laws continued into the 1990s. In 1991 Arizona, Arkansas, Rhode Island and Alabama all added such a law. Other states that added seat belt laws to their books in the 1990s included Delaware in 1992, Nebraska in 1993 and Massachusetts and Kentucky in 1994.ince their introduction, seat belts have saved countless lives and prevented many injuries. But making it mandatory to wear seat belts has been a slow process, as they were required by law in each state at a different time.
