Make sure that you check with the customs office to ensure that there are no additional rules that you need to know when transporting your vehicle internationally. First, you need a bill of sale as well as your car title. This will authorize the shipment of the car. Then the Bill of Lading is needed for international car transport. 

Also, there is another type called LO/LO (lift on/lift off), which uses a crane to load and unload the car. RO/RO cars are used on a built-in ramp. This is normally used for vehicles that are shipped internationally. This is often referred to as a Pure Car Carrier or Pure Car Truck Carrier.
