What is the required minimum age to rent a car in Kastela?
The minimum age to rent a car in most categories is 18, although it can be 21 for some suppliers. Bookings for large-sized and premium vehicles may be restricted to older age groups. A per-day young driver surcharge applies to drivers under 25. Since the required driver’s age varies by supplier, you should always confirm it in the rental terms before booking.
ℹ️ Some suppliers may set upper age limits, with drivers over 65 subject to a senior driver surcharge. Read the individual company policy before booking to confirm driver eligibility.
📄
What documents do I need to pick up a rental car?
You must have the following documents when picking up the car:
- Original Driver’s License held for at least 1–2 years, depending on the supplier
- Passport/National ID
- Valid Credit Card in the primary driver’s name for the security deposit
- International Driving Permit (IDP) if your domestic license uses a non-Latin script (Arabic, Chinese, Cyrillic, etc.)
- Rental Confirmation Voucher
⚠️ Travellers from non-EU countries must also provide an IDP along with their original driving licenses at the car rental pickup counter.

Can I add an additional driver to my car rental in Kaštela?
Yes. Additional drivers are optional extras you can add to your rental for a daily fee or flat fee. Sometimes, the first additional driver may be allowed at no extra cost, but charges apply for multiple additional drivers. Any extra driver(s) must be present at the pickup desk and are subject to the same age and license requirements as the main driver. Coverage is voided for any incident involving a driver not named in the rental agreement, so you should not allow them to drive.
✅ Sharing drive time with multiple drivers is a particularly useful and safer option for longer journeys around Istria. You can take turns driving for stretched day trips.
