most states requirements for wipers are determined by the car manufacturer
itself. if the vehicle came equipped with wipers they are required. however
with that being said in the state of new jersey if your car is registered as a
historic car, IE: QQ plates, state safety inspection at the dmv will not be
required and you can get away without wipers. on a different note there are
some nj specific requirements to get the car licensed and\or titled, i would suggest contacting the dmv for the specific info
