Yes, your spouse can almost always drive a rental car in Hawaii, but there is one crucial rule: you must list them as an additional driver on the rental agreement before they get behind the wheel. This is a non-negotiable requirement for all major rental companies to ensure their coverage remains valid.
The process is straightforward. When you pick up the car, present your spouse's valid driver's license at the counter and request to add them. The rental agent will process this, often for a daily fee. While this adds to the total cost, it is essential for compliance and peace of mind. If your spouse drives without being listed and is involved in an accident or even stopped for a routine traffic check, the rental company could void the collision damage waiver (CDW) and other insurance protections, leaving you fully liable for all damages.
Some companies, like Hertz with its "Spouse/Partner Policy," may waive the additional driver fee for a spouse or domestic partner if both drivers meet the company's age and license requirements. It's always best to check the specific policy of your chosen rental company when booking.
| Rental Company | Additional Driver Fee (Approximate) | Spouse Fee Waiver? | Key Requirement |
|---|---|---|---|
| Hertz | $13.50 per day | Yes (for spouse/partner) | Both drivers must be 25+ |
| Enterprise | $15.00 per day | Varies by location | Spouse must be present at pickup |
| Avis | $15.00 per day | Often waived for spouses | Must be added at time of rental |
| Budget | $15.00 per day | Subject to location policy | Valid license for all drivers |
| Alamo | $15.00 per day | Sometimes available | Must be listed on contract |
Beyond the formalities, sharing the driving in Hawaii is highly recommended. Roads like the Hana Highway on Maui or Saddle Road on the Big Island are winding and can be tiring for a single driver. Having a designated additional driver allows you both to enjoy the stunning scenery safely.

















Absolutely, but you have to do the paperwork. I learned this the easy way on our last trip. At the rental counter in Honolulu, I just handed over my wife's license and said, "Add her, please." Took two minutes and cost a few bucks a day. It's like a safety net—you hope you don't need it, but if a cop pulls her over or something happens, you're covered. Don't just hand them the keys; it's not worth the risk.

Think of it like this: the rental agreement is a contract for one specific driver—you. Letting your spouse drive without adding them is a breach of that contract. Rental companies run checks through their system to confirm the driver is approved. If an unlisted driver has an incident, the company's likely won't pay a dime. The small daily fee is a minor inconvenience compared to the potential financial disaster of being responsible for a totaled car.

Call your card company first. Many premium cards offer primary rental car insurance, but their coverage often voids immediately if an unauthorized driver is behind the wheel. I always check my card's benefits guide before I travel. Then, when I book the rental car, I look for the section on "additional drivers" on the website. It’s all about connecting the dots between your personal insurance, your credit card benefits, and the rental company's rules to avoid any gaps in coverage.

Living here, we see tourists get this wrong all the time. The rules in Hawaii are the same as the mainland. The police are very familiar with rental car agreements. If your spouse isn't on the contract and gets stopped, it's an immediate fine and a huge hassle. The rental companies are strict about it. Just be , add them at the counter, and then you can truly share the drive along the coast without a worry. It’s the only way to do it right.
