Bosnia & Cross-Border Travel

Yes. Since the Pelješac Bridge opened in 2022, the standard A1 motorway route stays entirely within Croatia. The bridge crosses directly from the mainland to the Pelješac peninsula, bypassing the short strip of Bosnian coastline at Neum that the route used to pass through.

Route	Passes through Bosnia?	Border crossings
A1 + Pelješac Bridge (standard route)	No	0
Old Neum corridor route	Yes	2 (exit Croatia, re-enter Croatia)
Detour via Mostar	Yes	2, plus time spent inland in Bosnia

⚠️ Important: Bosnia is unavoidable only if you choose the old Neum corridor instead of the bridge, or detour inland to Mostar or Sarajevo. For a standard Dubrovnik–Zagreb drive, there is no need to enter Bosnia, which most travellers now prefer.

💡 Traveller Tip: But it is completely reasonable to route through Bosnia in case you plan to visit Mostar. Supplier’s written authorisation, Green Card, and relevant cross-border fee (typically ~€40–100) apply in this case, something that the bridge route avoids.

A Green Card (international insurance certificate) is required only if you are entering Bosnia. For instance, if you take the older Neum corridor route instead of the Pelješac Bridge.

Requirement	Needed for Bosnia?
Green Card (proof of insurance)	Yes
Passport	Yes
Prior written authorisation from supplier	Yes, in almost all cases

📌 Note: Always confirm your supplier’s terms and policies before booking a car hire for a cross-border trip, rather than assuming.

Not necessarily. Standard Croatian rental insurance is valid within the country. Taking the hired car into another country, including Bosnia, generally requires prior written authorisation from the supplier and additional international motor insurance.

⚠️ Important: Crossing into Bosnia without that authorisation typically voids your insurance entirely. Getting involved in an accident abroad without the supplier’s approval or suitable insurance leaves you personally liable for all costs.
