Yes, tourists can drive in the EU in 2026, but the requirements depend on the country that issued your license. For U.S., Canadian, and UK citizens, a valid domestic driver's license is usually sufficient for short-term visits (under 90 days). However, it is a peer-to-peer "best practice" to obtain an International Driving Permit (IDP) before you leave home. While not always asked for at the rental counter, the IDP is a legal translation of your license that is mandatory in countries like Italy, Austria, and Greece. If you are pulled over by police without one, you can face immediate fines. In 2026, you must also be aware of "Low Emission Zones" (LEZ) in cities like Paris, Berlin, and Milan, which require a specific sticker (like the French Crit'Air) to enter. A high-value strategy is to always check the local rules for "ZTLs" (Limited Traffic Zones) in historic Italian towns, as these use cameras to issue automatic fines of €100+ to tourists who accidentally drive into restricted medieval centers.
