Short version: this tool is built for US license holders. If that is not you, treat every result as a starting point.
What the data actually covers
- Destination rules were compiled for a US license. A growing number have been checked individually against an official source; those show a citation and the date checked.
- Most entries still show “Compiled from AAA / US State Dept (not individually verified)”. They are plausible, not audited.
- Destinations with no entry say Unverified outright rather than guessing.
- Where reputable sources disagree, the result says Sources disagree and shows both positions.
Non-US licenses
One reciprocal agreement is covered properly: an EU/EEA license is valid across the whole EU/EEA under EU Directive 2006/126/EC, so those trips correctly say no IDP is needed and cite the directive.
Everything else is thinner. Every country is selectable, but for most of them we do not hold per-country destination rules, so those results fall back to general defaults and are labeled unverified rather than presented as findings. An EU driver heading outside the EU/EEA, or a UK driver anywhere, lands in that fallback - as does Switzerland, which sits outside the directive.
Where you apply
For the countries whose issuing authority we have confirmed, the result names it and links to it. For the rest we link the FIA member directory instead of guessing: it is a real route to the right body, and a wrong apply link is worse than an honest pointer.
Why we say so
Requirements change, and they vary by length of stay, rental company, and vehicle class. A confident answer built on an unchecked source is worse than an honest “we have not verified this”, so the app labels its own uncertainty rather than hiding it.
Always confirm with the destination’s embassy or your automobile association before driving. See also the FAQ and our terms & conditions.
