Handling a lost permit mid-trip.
If your IDP is lost or stolen during a trip, your underlying home license is typically still valid on its own in destinations that don't strictly require the permit, though you may face more friction at rental counters or checkpoints without it. Keeping a photo backup makes it easier to explain the situation if asked.
Since reissuing a permit generally isn't possible while abroad, most travelers in this situation continue their trip more carefully and address getting a replacement once they're back home for future travel.
