Is an International Driving Permit Legal and Valid?

An IDP's legal standing rests on two United Nations treaties: the 1949 Geneva Convention and the 1968 Vienna Convention on Road Traffic. Countries that have signed one or both agree to recognise an IDP issued under that convention's standard format, which is why the booklet translates your licence details into several languages and uses internationally agreed vehicle categories.

Because it follows this internationally agreed template, an IDP lets police, car rental staff and officials in a foreign country read and trust your driving entitlement even if they cannot read your home licence. It is essentially an official, recognised translation rather than a separate licence.

An IDP does not grant any driving rights of its own. It only confirms and translates the entitlement already shown on your national licence, so you must carry both documents and keep your home licence valid. If your licence expires or is suspended, the IDP becomes meaningless.

An IDP is also time-limited and destination-dependent. It is not a global driving licence, it does not let you drive categories you are not licensed for at home, and a country that has not signed either convention may not accept it at all. For long stays, many countries eventually require you to exchange your licence for a local one.

For an IDP to be accepted, it must follow the official convention format and be based on a genuine, valid national licence. A document that copies the look of an IDP but is not tied to a real licence, or that claims to replace a licence, is not a valid IDP and can cause problems at borders or with police.

International Drivers issues IDPs and certified translations based on your existing valid national licence, following the recognised formats. The key point is that any legitimate IDP is always an add-on to your real licence, not a substitute for passing a driving test.

Whether an IDP is required or merely recommended varies by country, and the convention a destination follows can affect which IDP format it expects. Before travelling, check the official guidance for your destination and confirm whether they accept the 1949 format, the 1968 format, or both.

Treat the IDP as part of a small document set: your valid national licence, your IDP, and your passport or ID. Carried together and kept current, they give you the strongest legal footing to drive abroad.
