Trying to find info on what the law is on safety belts in older model cars.
My '68 bug came w/ only lapbelts for the two front passengers... didn't know if to be in compliance w/ the law, I needed to install new ones that have both lap and shoulder restraints.
No by law all you need is what the car had when new.
My 1964 Valiant only has front Lap belts,and they were an option.
All "passenger motor vehicles" required by federal standards to be equipped with seat belts are covered. "Passenger motor vehicle" is defined as a motor vehicle designed for carrying ten or fewer passengers but excludes motorcycles, mopeds or trailers. All passenger cars manufactured after 1967 are required by federal law to have seat belts. Requirements for vans, pickup trucks and sport utility vehicles to be equipped with belts began with the models manufactured after 1971. There are no exemptions for vehicles registered in other states.
Looks like 1968 was the changeover year.
