Can I drive a Hertz car rental from Croatia to a neighbouring country?
Yes, cross-border Hertz car rentals from Croatia are allowed with prior approval. You must also declare your intended destination at the time of booking and at the pickup counter. A cross-border fee of around €40 and an international insurance certificate (Green Card) are also often required.
⚠️ Driving across a border without the supplier’s written authorisation voids the insurance and incurs heavy penalties. Meaning that you will be fully responsible for the costs of vehicle damage or third-party claims in the event of unauthorised cross-border travel.

Is taking a Hertz car rental on a ferry allowed in Croatia?
Yes, travellers can take a Hertz rental car on domestic ferries within Croatia with prior written authorisation and after paying an added fee of about €5/day (max €75). Ferrying with hired cars may not be allowed to all islands, so you should confirm that before booking. International ferry transfers are usually prohibited in this case.
⚠️ A Ferryboat Travel Cover (FBF) is also required by the company for moving the vehicle on ferries to Croatian islands, as standard insurance does not cover on-vessel damage.

What is the Hertz car rental fuel policy in Croatia?
Hertz uses two different fuel policies, depending on your rental duration. Return the car in accordance with the agreed-upon fuel policy to avoid higher-than-market-rate refuelling and service charges.
| Rental Length | How It Works |
| 1–2 days | Return with the same fuel level shown at pickup. Returning with less means paying for the missing fuel plus a €30 refuelling service charge. |
| 3+ days | Prepay the full tank’s value at pickup. Ask for a refund of unused fuel at return – if you’re below what you prepaid, a €20 refuelling service charge applies instead of €30. |
