The minimum age to rent a car in Hawaii is typically 21 years old. However, renters between the ages of 21 and 24 will almost always face a Young Renter Fee, a daily surcharge that can significantly increase the total rental cost. The only universal exception is for active-duty U.S. military personnel, who can often rent from age 18 with valid military ID. It's crucial to understand that while state law permits renting at 21, individual rental companies set their own policies, including age restrictions and fees.
The primary challenge for drivers under 25 is the additional cost. The Young Renter Fee is a daily charge applied on top of the rental rate. This fee exists because rental companies statistically view younger drivers as a higher risk. The cost varies by company but can range from $25 to $50 per day. When comparing rental quotes, you must factor in this daily surcharge to understand the true total price.
Some companies may also restrict the class of vehicle available to younger drivers, often excluding premium cars, SUVs, or convertibles. Always check the specific policy of the company you plan to use directly on their website or by calling them. Be prepared to show a valid driver's license, a major credit card in your name for the security deposit, and proof of insurance if you are not purchasing their coverage.

Just turned 21 and planning your Hawaii trip? You can rent a car, but budget for the "young driver fee." It's an extra daily charge, sometimes over $30, that you'll see when you book. My advice is to use the official websites for companies like Enterprise or Hertz. Their policies are clear, and you can get a final price that includes all the fees before you commit. Don't get surprised at the counter.
