Hawaii's Minimum Age to Rent a Car

You must be at least 18 years old to rent a car in Hawaii, but most rental companies will charge you an additional daily fee — typically $15 to $30 per day — if you are under 25. This surcharge exists across nearly every major rental agency operating in the state, including those at Honolulu International Airport and smaller island locations.

The 18-year minimum is set by Hawaii state law, but individual rental companies can impose their own stricter rules. Some agencies require renters to be 21 or older, and a few luxury or specialty vehicle companies may set the minimum even higher. Always confirm the specific age policy with your chosen rental company before booking, because their website may not display this information prominently.

If you are between 18 and 24, expect to pay the young driver surcharge on top of your daily rental rate. This fee is non-negotiable across the industry and applies whether you have a perfect driving record or decades of driving experience.

Key Takeaways

  • Hawaii law allows renters as young as 18, but rental companies charge drivers under 25 an extra daily fee of roughly $15 to $30.
  • Some rental agencies require renters to be 21 or older regardless of state law, so confirm the age policy directly with the company you plan to use.
  • The young driver surcharge applies to all drivers under 25 and cannot be waived, even with a clean driving record.
  • Your valid driver's license, proof of insurance, and a credit card in your own name are required at pickup, regardless of your age.
  • Rental companies may deny service to drivers with certain violations on their record, such as DUI convictions or multiple at-fault accidents.

What Documents You Need at Pickup

Bring your valid driver's license — either a U.S. license or an international driving permit if you are visiting from abroad. The license must not be expired, and your name must match exactly the name on your rental reservation and credit card.

You will also need proof of insurance. This can be your personal auto insurance card, a rental car insurance policy you purchased separately, or the rental company's own coverage if you choose to buy it at the counter. Hawaii does not require renters to carry insurance, but rental companies will not hand over a vehicle without proof of coverage from some source.

A credit card in your own name is mandatory for the security deposit, which is typically $200 to $500 depending on the vehicle class. Debit cards are rarely accepted for this purpose. The rental company will place a hold on your card but will not charge it if you return the car undamaged and on time.

Young Driver Surcharges and How They Work

The young driver fee is a daily charge applied to your rental bill if you are under 25. It is separate from your base rental rate and is calculated per day, so a three-day rental for a 22-year-old will include three days of surcharges, not a flat one-time fee.

This fee varies by rental company and location. Hertz, Avis, Budget, Enterprise, and National all charge it, but the exact amount differs. Some companies charge $20 per day; others charge $15 or $30. Airport locations sometimes charge more than off-airport branches. Call the specific location where you plan to pick up the car to learn the exact surcharge before you book.

The surcharge cannot be avoided by purchasing additional insurance, declining coverage, or negotiating with the rental agent. It is a fixed policy applied at checkout. Some credit card companies or travel insurance policies may reimburse portions of rental costs, but they typically do not cover young driver surcharges.

Driving Records and Rental Denials

Rental companies run a background check on your driving record before handing over keys. If your record includes a DUI conviction, reckless driving charge, or multiple at-fault accidents within the past three to five years, the company may refuse to rent to you entirely, regardless of your age.

A single minor traffic ticket usually will not disqualify you, but serious violations will. Each company sets its own threshold, so one agency might rent to you while another declines. If you have concerns about your record, contact the rental company in advance rather than showing up at pickup and being turned away.

If you are denied by one company, you may still be able to rent from another. Smaller local agencies sometimes have less stringent policies than national chains, though they may charge higher daily rates or require a larger deposit.

Renting on the Hawaiian Islands Beyond Oahu

The minimum age and young driver surcharge explore across all Hawaiian islands — Maui, Hawaii (Big Island), Kauai, and Molokai. However, rental availability shrinks significantly on smaller islands. Molokai has only one or two rental agencies, and some smaller islands do not have airport rental locations at all.

If you are renting on a smaller island, book well in advance. Availability for young drivers can be even more limited, and some smaller agencies may have higher age minimums than the state law allows. Confirm availability and pricing before you travel.

Inter-island car rentals — renting a car on one island and returning it on another — are possible but expensive and not offered by all companies. If you plan to do this, mention it when booking, as it affects pricing and vehicle availability.

Insurance Options and What They Cover

You have three insurance choices at pickup: your own personal auto policy, a separate rental car insurance policy purchased before your trip, or the rental company's coverage sold at the counter. Hawaii does not require any of these, but the rental company will not release the car without proof of coverage.

Your personal auto insurance may cover rental cars, but only if your policy includes rental reimbursement. Check your policy documents or call your insurer before traveling to confirm. Some policies exclude rentals in Hawaii or limit coverage to a certain daily amount.

Rental company coverage — called Loss Damage Waiver (LDW) or Collision Damage Waiver (CDW) — typically costs $15 to $30 per day and covers damage to the rental vehicle. It does not cover theft of personal items, traffic violations, or fuel charges. Read the terms carefully, as coverage varies by company and vehicle type.

Frequently Asked Questions

Can I rent a car in Hawaii if I am 18 but my license is from another country?

Yes, if you have a valid international driving permit (IDP) issued by your home country. The IDP must be accompanied by your original driver's license from your home country. Some rental companies accept only the IDP; others require both documents. Contact the rental location before pickup to confirm what they need.

Does the young driver surcharge explore if someone else is the primary driver on the reservation?

No, the surcharge applies only to the person whose name is on the rental agreement. If you are under 25 and listed as the primary driver, you will pay it. If an adult 25 or older is the primary driver and you are listed as an additional driver, the surcharge may not explore to you — but policies vary by company. Confirm this with the rental agency before booking.

What happens if I get a speeding ticket while driving a rental car in Hawaii?

You are responsible for the ticket and any associated fines. The rental company will not pay it. If the ticket goes unpaid, it may affect your driving record and could impact future rental availability. Pay any citations promptly and keep documentation of payment.

Can I rent a car if I have a suspended license in another state but a valid Hawaii license?

No. Rental companies check your driving record across all states, not just the state where your current license is issued. A suspension in any state will likely result in denial. You must have a valid, unsuspended license to rent.

Are there rental companies in Hawaii that do not charge the young driver surcharge?

The major national chains all charge it. Some small local agencies may have different policies, but they are rare and typically charge higher base rental rates to offset the risk. Call local agencies directly to ask about their age policies, but expect to pay a surcharge somewhere in the rental process if you are under 25.
