Essential Driving Rules and Regulations

Driving in Porto Alegre requires strict adherence to Brazilian federal traffic laws. Here are the core rules every driver must observe:

• Driver's License Validity: Foreign tourists can legally drive using their valid national driver's license for up to 180 days from the date of entry into Brazil.
• US License Documentation: Drivers holding a United States license must carry either an Inter-American Driving Permit (IADP) or an official certified Portuguese translation (tradução juramentada) alongside their physical license.

When driving out of the metropolitan area, keep your physical driver's license, passport, and car rental contract inside the vehicle at all times.
