Travelers head to Portugal for the Algarve coastline and Douro Valley wine routes, and it's a solid pick for relaxed coastal touring. Here's what's genuinely useful to know before you get on the road.
Toll roads around Lisbon and the Algarve use electronic-only tolling with no cash booths; rental companies typically bill tolls separately after your trip.
Beyond that, the basics apply everywhere: rental staff and local authorities in Portugal typically want to see your passport, your domestic license, and your international driving permit together. Keeping all three ready at pickup saves time.
Portugal traffic keeps to the right. This will feel familiar if you're used to driving in North America or most of continental Europe.
Many rental agencies and authorities in Portugal recognize an international driving permit alongside a valid domestic license, though requirements can change. Confirm current rules for your specific trip before you travel.
