I am trying to uncover the requirements around seat belt regulations for driver as well as front and rear passengers, regardless of age, height and/or weight, while traveling in vehicles that date before a new law was passed.
"By 1964, more than half of U.S. states required cars to have seat belts in the front seat, but the rear seat belt was not even standard until 1968. However, the first law requiring the use of seat belts was not passed until almost 20 years later. The first seat belt law was passed in 1984 in New York state."

Therefore, if I had a 1950 vehicle, can passengers, regardless of age, height and/or weight, travel all day long without a seat belt and be legal to do so? Also, what would be the last year a vehicle as well as occupants driving in the vehicle are not subject to the new regulations/
While I am fully aware of the principles surrounding this topic, I am mostly interested in the technicality of the subject.

Upon further research, I may have found the answer to my own question...
"Vehicles made before 1964 that were not manufactured with seat belts installed are grandfathered from the seat belt requirement."
Yet, what about pre-1964 vehicles that did come equipped with seat belts? When did land rover begin installing front and rear seat belts into their defender and series vehicles?
