📄
What documents do I need for a cross-border car rental from Croatia to Montenegro?
The required documentation for all standard rentals in Croatia is given below. However, suppliers may require additional paperwork for cross-border travel and your country of residence.
| Document | Requirement |
| Passport | Required; EU national ID accepted but passport recommended |
| Driving licence | Held 12+ months |
| International Driving Permit (IDP) | Required only for non-EU and non-Latin script licences |
| Rental agreement | Must show the cross-border clause in writing |
| Vehicle registration | Carry the original, not a copy |
⚠️The border security officers at the Montenegrin checkpoint specifically inquire about the written cross-border authorisation in your agreement. Cars without proper documentation are often returned.
🧑
What is the minimum age for a cross-border rental from Croatia to Montenegro?
Drivers must be at least 21 in most cases, though the required minimum age can also be 23–25 for larger or luxury vehicles or specific supplier policies. Drivers under 25 are often subject to a young-driver surcharge on top of the standard rate.
✅ Refer to the terms of a favourable deal to confirm your eligibility before making a reservation.
🟩
Do I need a Green Card to drive into Montenegro?
Montenegro is a member of the international Green Card insurance system. This means that the Third Party Insurance for your Croatian rental car extends automatically once the Green Card is issued for your agreement.
ℹ️ Green Card may be offered by several suppliers as part of the deal at no extra cost; a few others may still charge a separate fee for it.
