International Driving Permit Age Requirements: How Old to Hold One and Rent Abroad
You generally must be 18 to hold an IDP, but rental minimums, young-driver surcharges under 25, and senior age caps are set separately by each country and rental company.
The age to hold an IDP: usually 18
The permit itself carries a straightforward minimum: applicants must generally be at least 18 years old, and AAA states this qualification plainly on its US application. Just as importantly, you must already hold a valid national driving licence, because the IDP only translates that licence — it grants no driving rights of its own and cannot be issued to someone who is not yet licensed to drive at home.
That means a newly licensed 17-year-old in a jurisdiction that licenses at 16 or 17 typically cannot obtain an IDP until they reach 18, even though they can already drive domestically. The permit is a translation layered on top of an existing licence, so the age floor for the permit sits at 18 regardless of when local driving rights began.
The age to rent a car is set separately
Holding an IDP does not entitle you to rent a vehicle at any particular age — car-rental minimums are set by the rental company and the country, entirely apart from the permit. Minimum rental ages commonly range from 18 to 21, and in much of Europe and North America the practical floor is 21. Many companies also require that you have held your licence for at least a year, so a driver who was licensed only recently may be turned away even if old enough on paper.
The two requirements stack rather than override each other. You need to satisfy the IDP's age rule, the rental company's minimum age, and the country's own rules all at once. The permit ensures your licence is readable and recognised; it does nothing to lower a rental company's age threshold.
Young-driver surcharges under 25
Between the minimum rental age and 25, most companies apply a young-driver surcharge — a daily fee reflecting the higher accident risk statistically associated with younger drivers rather than a penalty. Figures vary widely by market, commonly falling in the region of roughly €10 to €30 or more per day, and some companies restrict younger renters to certain vehicle categories or require additional cover.
An IDP does not reduce or remove these surcharges, and it should never be sold as a way around them. What it does do is keep the licensing side clean so a young driver is not refused outright at the desk for an untranslated licence on top of the age question. Budgeting for the surcharge, and confirming the exact figure with your chosen company in advance, avoids surprises at pickup.
Senior drivers and maximum-age rules
At the other end, some countries and rental companies apply maximum-age limits or extra conditions for older drivers, such as a medical certificate, a higher excess, or restricted availability above a certain age. These rules are inconsistent — many destinations have no upper limit at all, while a handful cap rentals or add requirements past 70 or 75. There is no single global standard.
As with young drivers, the IDP is neutral here: it neither imposes nor removes an upper age limit, and a senior driver who is validly licensed at home can hold a permit in the ordinary way. The practical step is to check the specific rental company's and country's senior policy before booking, since this is where the variation lives rather than in the permit.
What this means when you apply
The clean way to think about it: the IDP has one age rule — generally 18 and an existing valid licence — while every other age question belongs to the rental company and the country. Confirm your destination's rental minimum, whether a young-driver surcharge applies to you, and any senior conditions, all separately from the permit.
International Driver Licence issues your permit in the convention format your destination recognises, in as fast as 8 minutes. It is a certified translation of your national licence carried with the original — not a licence, not a government-issued permit, and not a document that changes any age threshold. Where a country legally requires its official government IDP, this provides the correct format but does not substitute for that requirement.
