Driving with a US License in Brasil

Many newcomers want to drive soon after arriving: to explore beyond the city, to reach a beach, or because public transport does not cover their routine. A US license can be used in Brasil for a limited time, with the right documents. After that, you need a Brazilian license.

This guide summarizes the page from Senatran, the national traffic department within the Ministry of Transport. Rules are set by CONTRAN Resolution 1,020 of December 1, 2025, and the Brazilian Traffic Code.

The first 180 days

Senatran says that a driver licensed in a foreign country may drive in Brasil for 180 days, when covered by international conventions or agreements that Brasil has ratified. The driver must carry:

1. A valid foreign driving license.
2. An International Driving Permit, together with the license, when the documents come from a contracting party to the 1968 Vienna Convention on Road Traffic.
3. An identification document.
4. A document that proves the date of entry into the country.

Point 2 is the one to check. Whether you need an International Driving Permit depends on whether the country that issued your license is a party to the 1968 Vienna Convention. Senatran links to the list of contracting parties. Check the official page and the list for the US before you travel, rather than relying on what a rental desk or a forum says.

The proof of entry matters because the 180 days are counted from your entry. Keep your boarding pass or entry record with your license.

After 180 days

Senatran says that after 180 days of regular stay, a foreign driver who wants to keep driving must go to the DETRAN, the state traffic department, of their domicile. The process involves physical and mental fitness exams and a psychological evaluation, under article 147 of the Traffic Code, to obtain a Brazilian license, the CNH.

For licenses not recognized by the Brazilian government, the page adds a driving test. Which situation applies to a US license, and which documents your DETRAN wants, is set at state level. Check the official page and the DETRAN site for your state.

Renting a car

Rental companies set their own requirements on top of the law, such as minimum age, a credit card in the driver's name and how long you have held your license. Ask before you book. See Renting a car abroad for insurance and inspection habits.

On the road

A few general habits help in any new country:

• Carry the documents every time. License, permit if needed, ID and proof of entry.
• Learn the local rules before you drive, including speed limits, alcohol rules and how roundabouts work. Brasil has its own rules on alcohol and driving; check the official page and do not assume they match home.
• Use navigation, but think. Apps may route you through areas you would avoid on foot. Stick to main roads when in doubt.
• Keep windows up and valuables out of sight at traffic lights in cities.
• Know the emergency numbers. 192 for medical help, 193 for the fire brigade, 191 on federal highways. See Emergency numbers.

Checklist

1. Check whether you need an International Driving Permit for a US license.
2. Carry license, permit if needed, ID and proof of entry.
3. Note the date when your 180 days end.
4. Before then, contact your state DETRAN about the CNH.
5. Confirm the rental company's own requirements.

Common questions

Does the 180-day count restart when I leave and come back? The page refers to 180 days of regular stay. How exits and re-entries are counted is a question for the official page and your DETRAN.

Can I drive a motorcycle? Only within the category on your license. Check the official page.

Mistakes to avoid

• Leaving proof of entry at home. The 180 days are counted from your entry. Keep the proof with your license.
• Assuming a rental counter checks the law for you. The rental company checks its own rules. Whether you need a permit is your responsibility.
• Losing track of day 180. Put the date in your calendar the day you arrive, with a reminder a month earlier for the DETRAN.
• Driving outside your license category. A car license does not cover a motorcycle.
