If the vehicle was built with seat belts you have to have them but if it didn't have the belts from the factory your not required to have them.
yes if the car is equipped with seat belts.
Not if they did not come from the factory with seat belts. If they came form the factory with seat belts you are required to wear them.
Children up to certain weights are required to be in car seats that are held in place with the seat belts in most states. After they reach a certain weight, they are required to wear seat belts, so not only can children wear seat belts, after they no longer are required to be in car seats, they are required to wear a seat belt.
If the vehicle came equipped from the factory with belts it has to have them.
Whatever the vehicle came with when it left the factory is what is required.
That vehicle had seat belts in it when it left the factory so it should have threaded holes in the floor where they were once mounted. Purchase aftermarket seat belts for that vehicle and bolt them in.
not all classic cars have to have a seatbelt.cars that are from 1963 or older is legal to drive without a seatbelt.
just the very back seat, they are normal seatbelts.
If it was not equipped with seat belts when it left the factory new, it is not required. That is in the state of Connecticut, USA. Check with your local DMV.
if the car didn't come with seat belts on those seats from factory you don't need them. but i'd say put seat belts in anyway you can never be to safe.
