A valid home-country license is essential, yet many borders and rental desks ask for an International Driving Permit to support non-Latin scripts or satisfy policy. Minimum age can increase for cross-border use, and young-driver surcharges can multiply overall costs. If your license has a short validity remaining, renew before departure. Always carry a passport, a second ID, and any residency documents if applicable. Tell us if an IDP saved your day, or how a grace period on license renewal was interpreted during your inspection.
The single most common failure point is arriving at a border without original vehicle registration or a written company authorization permitting international travel and one-way drop. These documents prove you’re not attempting unauthorized export. Request them during booking, then re-confirm at pick-up, inspecting names, plate numbers, and chassis references. Photocopies help, but originals are frequently required for inspection. If you had a border officer demand a specific stamp or phrase, share that exact wording. Your comment may spare another traveler an expensive turnaround.
The international Green Card (or regional equivalents) validates third-party liability beyond your starting country. However, it may exclude certain destinations or specific classes of vehicle. Collision Damage Waiver and Theft Protection do not equal border permission; they limit financial exposure, not legal crossing rights. Ask for written confirmation naming every country you’ll enter, and verify roadside assistance coverage follows you. If a clerk insisted on additional cross-border insurance, note the price and conditions in the comments. Real data helps everyone budget and avoid friction.
