A title is issue only once in the life of a vehicle and lasts as long as the vehicle exists. Normally, a vehicle does not have to meet any regulations nor even to work in order to be become a titled entity. In order to actually operate a vehicle on the public roadways or waterways, however, it must be licensed. A license will be issued on a homebuilt vehicle only if it meets applicable standards of construction and is appropriately equipped. A license will have to be annually renewed by paying a fee.
Vehicle manufacturers have to comply with federal regulations in the construction of their products.
They are not regulated on a federal level. Normally, the state-level regulations that apply to such vehicles are less stringent than the federal regulations that apply to manufactured products, but much depends on the state in which you live. For example, the motor vehicle code of many states contains language requiring that all motor vehicles are equipped according to the federal regulations in effect when the vehicle was manufactured. Homebuilt aircraft and watercraft must comply with federal regulations. Visit the appropriate agency in your state and obtain a list of the required equipment and inspection procedures applicable to your vehicle.
