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.
According to Wikipedia, the first safety belts were installed in a race car named Baker Torpedo (never heard about that) in 1902. 1948 Tucker fitted its Tucker Torpedo with two point safety belts on all seats. 1959 Volvo got a patent on the three point safety belts we know today.
