Cross-border fee
A surcharge applied when a rental vehicle is driven into another country — covers the insurance extension, registration paperwork, and recovery cost from foreign soil.
A cross-border fee applies when the renter drives the vehicle outside the country it was rented in. The fee covers three real costs: extending the rental insurance to be valid in the destination country, the additional paperwork (a "green card" or equivalent registration authorization), and the higher recovery cost if the vehicle breaks down or is impounded abroad. The exact amount depends on the destination — neighbouring EU countries are cheap, the Balkans and Eastern Europe more expensive.
Some routes are flat-out forbidden by the operator and not just surcharged: a rental from Germany usually cannot cross into Belarus or Russia, a rental from Spain cannot enter Morocco. The rental contract lists which countries are permitted, and entering a banned country voids every waiver. The renter is then personally liable for any damage and may be reported for unauthorized use of the vehicle.
In renviq, cross-border permissions and fees are configured per vehicle and per destination country: a vehicle either has a list of allowed countries or it doesn't, and each allowed country gets a fee. The agreement template prints the renter's permitted route alongside the fees, so the contract is explicit about what was authorized.
