If you only need car insurance in Hawaii for a short time as a car owner, you can buy a policy and cancel it before the six-month term is up. You may get a full refund for canceling early. A three-month car insurance policy typically costs $267 on average.
If you do not own your own car in Hawaii or are just visiting the state, rental car insurance could be the best option for you.
MoneyGeek also outlined other possible situations where temporary car insurance is needed, including working for rideshare companies.
