If you have just recently been allowed of shipping car to Hawaii, the next thing you should do is have the vehicle registered in the island. You need to proceed to the City Hall Office or to the Motor Vehicle Office to secure registration application. This will need to specify your current address. The office will then ask you to surrender your previous registration card and the title. You can present the Bill of Sale to prove that you actually bought the car.
