An International Driving Permit costs under $40 and takes minutes to get. But the mistakes people make around IDPs can cost hundreds or even thousands of dollars in fines, lost rental deposits, and ruined travel plans. We have seen every one of these errors play out in real life. Here are the seven most common, along with exactly how to avoid them.
1 Not Getting an IDP at All
The consequence: You arrive at the rental counter and get turned away. Or worse, you drive without one and get pulled over. In countries like Japan, Thailand, and the UAE, driving without a valid IDP is a fineable offence. Fines vary by country but can run from $100 to over $500, and in some jurisdictions your vehicle can be impounded.
How to avoid it: Check whether your destination requires an IDP before you book your rental car, not after. Use the Permio Country Checker for an instant answer. One traveler learned this the hard way in Japan when she nearly lost her entire road trip over this single oversight.
2 Getting a Fake IDP From a Scam Site
The consequence: You pay for a document that looks official but has no legal standing. At a police checkpoint or rental counter, it is rejected. You have wasted your money and you still have no valid permit. In some cases, presenting a fraudulent document can create legal problems of its own.
How to avoid it: Only use recognized, legitimate IDP providers. Red flags include sites that promise instant PDF delivery with no verification, suspiciously low prices, no physical address, and no clear explanation of which international convention their permit follows. Permio issues permits that comply with the Vienna and Geneva Conventions and includes full verification of your licence before issuing. See our comparison guide to understand how providers differ.
A legitimate IDP provider will verify your identity and licence before issuing a permit. Any site that delivers an IDP in seconds without checking your documents is almost certainly issuing a worthless piece of paper.
3 Assuming Your Licence Is Enough
The consequence: Many travelers assume that because their domestic licence is accepted at home, it will be accepted everywhere. It will not. Even in countries where an IDP is not strictly required by law, rental companies frequently demand one. Showing up without it means no car, and often no refund on your prepaid booking.
How to avoid it: Do not rely on assumptions. Check both the legal requirements and the rental company's specific policies. A traveler in Greece experienced this exact situation when the rental counter refused to honor a fully paid reservation.

4 Letting Your IDP Expire Mid-Trip
The consequence: Your IDP has an expiration date. If it expires while you are still abroad and still driving, you are technically driving without a valid permit from that moment forward. If you are in an accident or stopped by police, your insurance coverage may also be voided.
How to avoid it: Before your trip, check that your IDP will remain valid for the entire duration of your time abroad, including any buffer for unexpected extensions. If your permit is close to expiring, renew it before you leave. Frequent travelers should consider a 3-year IDP to avoid this problem entirely.
5 Not Carrying Both Your IDP and Original Licence
The consequence: An IDP is a translation of your domestic licence, not a replacement for it. It has no legal standing on its own. If you carry your IDP but leave your original licence at the hotel, the IDP is meaningless at a checkpoint. Police and rental agents need to see both documents together.
How to avoid it: Always keep your IDP and your original driving licence together. Some travelers keep both in a small travel document wallet along with their passport. If you leave one in the hotel safe, take them both out before driving.
6 Wrong Licence Category
The consequence: IDPs are issued for specific vehicle categories. A standard car-only IDP does not cover motorcycles, mopeds, or larger vehicles. If you rent a scooter in Bali with a car-category IDP and get into an accident, your insurance claim can be denied entirely. In Thailand, riding a motorcycle without the correct IDP category can result in a fine and seizure of the vehicle.
How to avoid it: When applying for your IDP, make sure you include all the vehicle categories you might use during your trip. If there is any chance you will rent a motorcycle or scooter abroad, add the motorcycle category to your IDP. This is especially important in Southeast Asia, where scooter rentals are extremely common. Your home licence must also include the motorcycle category for it to be added to your IDP.
In countries like Thailand, Vietnam, and Indonesia, scooter rentals are everywhere. Many travelers rent one on impulse. If your IDP only covers cars, you are not covered. Add motorcycle categories before you travel, not after you arrive.
7 Not Checking Country-Specific Rules
The consequence: Different countries follow different international conventions. Japan only accepts IDPs issued under the 1949 Geneva Convention. Most of Europe follows the 1968 Vienna Convention. Some countries accept both. If you arrive with the wrong type of IDP, it can be rejected entirely, as one traveler discovered in Dubai at a police checkpoint.
How to avoid it: Before you apply, check the specific convention requirements for your destination. Permio issues IDPs that comply with both conventions, covering the widest range of countries. Use the Country Checker to see the exact requirements for wherever you are headed.
