The state gives you two choices in registering your vehicle: Transfer it to Hawaii registration, or get a permit to operate it until the out-of-state plates expire.

Before you go to register your car, you must have a Hawaii Vehicle Inspection Certificate from any authorized safety inspection provider on the island, such as a gas station which displays a state-authorized Safety Inspection seal. You'll need to show your Hawaii proof of motor vehicle insurance card to get your Hawaii inspection certificate.
