Driving in Brazil: What Foreigners Need to Know

Where this rule actually lives

Brazil's traffic law is the CTB (Código de Trânsito Brasileiro), Law 9,503 of 1997, and it does not answer the question. Article 142 hands it off in a single line: recognizing a license obtained in another country depends on international conventions and on the rules of CONTRAN. Then the code is done with you.

CONTRAN (Conselho Nacional de Trânsito) is the federal council that writes the operating rules the code leaves open, and its resolutions are where a visitor's answer sits. The one in force is Resolution 1,020/2025, printed in the Diário Oficial da União — the federal gazette, where a Brazilian rule becomes real — on 9 December 2025, effective that day.

Article 140 of that resolution repealed Resolution 933/2022 — the rule English-language advice still rests on. The trail is live, and you can check it: a Rio de Janeiro state licensing page we read on 27 August 2026 opens by naming 933/2022 as the governing rule. The 180-day period survived the change untouched; the legal basis quoted underneath it did not.

A trap waits for anyone who checks by searching. Ask the new resolution for "180" and it returns nothing — the text spells the number out, cento e oitenta dias. Ask it for "PID", the Portuguese abbreviation for an international permit, and it returns nothing either, because that term is always written in full. Two searches, two zeroes, on a document that governs both. An empty result looks exactly like proof the rule is gone.

It survived a scare, too: a federal court in Mato Grosso suspended it on 16 December 2025, and the Federal Regional Court of the 1st Region suspended that decision seven days later.

How long you can drive, and what ends it sooner

Article 102 sets a ceiling of one hundred and eighty days, and attaches a second condition in the same breath: the license from home has to still be valid. Two clocks run at once, and the first to expire ends your permission. A license due to run out in three months buys you three months, not six.

Paragraph 1 fixes when counting starts: the date you entered Brazilian territory. Not the day you collect a car, not the day you reach the city you came for. Spend five months on a beach before deciding to drive and you have one month left — and article 102 expects you to carry something proving the date you arrived, the item travelers are least likely to have kept.

Two narrow points remain. Career diplomats and consuls sit outside all of it, by paragraph 6. And a person holding both a Brazilian license and a foreign one cannot fall back on the foreign document while the Brazilian one is out of date — Detran-RJ, the Rio de Janeiro licensing authority, says so flatly.

Recognized, not recognized, and the age Brazil will not bend

Everything above applies to one group of drivers. A second group does not get 180 days of anything.

Article 103 covers a license Brazil does not recognize. That driver may only drive after trading the foreign license for a Brazilian one, and the trade carries a road test on top of the health assessments. Permission does not exist first and expire later; it begins after the swap. Which group you land in turns on which treaty issued your license — the subject of a separate guide on the international driving permit, where the treaty map and the country-by-country picture live.

No single roster of recognized countries is published. Article 102 tells the federal traffic authority to inform the rest of the system which countries it covers; what the public is handed is the United Nations list of parties to the 1968 Vienna Convention, plus CONTRAN's own copy of it, dated 2020 and titled for Brazilians driving abroad.

Age is the part nobody sees coming. Joining the Vienna Convention, Brazil filed a declaration refusing to recognize in its territory driving permits held by people under eighteen years of age — and a second refusing them, under twenty-one, for categories C, D and E, the trucks, buses and heavy combinations. Teenagers hold full licenses at sixteen or seventeen in much of the United States, Canada and Australia. Those licenses are not recognized here, whatever treaty their country belongs to.

The floor is not a quirk of one treaty. The 1943 Inter-American Convention, ratified by Brazil in 1944, puts it in one sentence: "No operator shall be admitted to international travel who is less than 18 years of age."

What it costs to be stopped without a valid license

Two articles decide it. Article 258, I prices a gravíssima — the heaviest of the code's four grades of infraction — at R$ 293.47. Article 162, I puts unlicensed driving in that grade and multiplies the fine by three, landing at R$ 880.41. The part travelers underestimate is the measure attached: the vehicle is held until somebody licensed arrives to take it away.

We leave open which item an officer reaches for when a foreign license runs past its date: no item in the code is written for that case, and no enforcement guidance fills the hole. What the code does contain, written for foreign drivers and nobody else, is article 230, paragraph 2 — releasing the held vehicle is conditioned on paying or depositing the fine. Across the whole compiled code the phrase "condutor estrangeiro" turns up exactly once, and this is it. The car moves after the money does, which is worth reading next to getting cash when your card is foreign.

One further rule applies only to you. Where the infraction carries a suspension, article 106 of the resolution directs the authority to hold the foreign license until the suspension runs out or the driver leaves the country, to notify the authority abroad that issued it, and, where the document has international validity, to write on it that it is not valid in Brazilian territory.

Three rules that catch out drivers who are fine at home

There is no allowance for alcohol. Article 276 is one sentence: any concentration of alcohol per liter of blood or of exhaled air subjects the driver to the penalties of article 165. CONTRAN may set tolerance margins for measuring instruments, which is not the same as a permitted amount. The penalty is a gravíssima fine applied ten times, R$ 2,934.70, plus a twelve-month suspension, the license document taken and the car held. Past 0.3 mg per liter of exhaled air, or with visible signs of impairment, it leaves the administrative world entirely: article 306 makes it a crime carrying six months to three years of detention. One beer with lunch is not a rounding error here.

The child restraint rule is age and height together, in one test. Article 64, in the wording given by Law 14,071 of 2020, puts children under ten who have not reached 1.45 m in the back seats, in a restraint suited to age, weight and height. Foreign advice lags here: the archived US State Department country page for Brazil, whose live version refused our requests, still describes a scheme built on "under 7½" and "7½ to 10" that the 2020 wording replaced. Getting it wrong is article 168 — gravíssima, and the car is held until it is put right.

Priority at an unmarked junction is a ladder, not a rule about the right. Article 29, III ranks it: if only one of the two flows comes off a rodovia, a highway, that flow goes first; at a roundabout, the vehicle already circulating goes first; and only in the remaining cases does the one arriving from your right have priority. "Yield to the right" is the short version that circulates in English, and it is wrong in the place it matters most to a visitor, which is the roundabout.

The rental counter is a second gate

Satisfying the regulation gets you past a police stop. It does not get you a car.

The desk answers to a rental contract, and the Brazilian chains that publish theirs ask a foreign driver for things no traffic rule mentions. The mistake runs both ways: meeting every line of article 102 does not guarantee the keys, and being turned away at a counter says nothing about whether you were legal to drive. Which company asks for what — and what the proteção sold beside it leaves out — is worked through in what the rental protection does not cover.

One item spans both gates: proof of your date of entry. The state wants it and the contracts want it, and it is the piece of paper nobody keeps. The deposit is a separate problem, held as a pre-authorization on a credit card in the renter's own name — see what a Brazilian terminal does with a foreign card, under money and payments.

When the visit turns into a life

Past 180 days of regular stay, article 102 requires the medical fitness examination and the psychological assessment set by article 147 of the code, and then a Brazilian license. For a recognized license that is the whole list — no theory paper, no road test. The article 103 route adds the road test.

Those two assessments now carry a national price ceiling: Portaria SENATRAN 927/2025, published on 12 December 2025, says in its article 2 that together they may not exceed R$ 180.00. A ceiling is not a price list. Detran-PR, the Paraná licensing authority, publishes that figure and adds that the amounts charged in Paraná still come from state law and live contracts with accredited clinics.

Conversion is a resident's procedure, not a visitor's. Detran-RJ will not accept a declaration of residence on a first application, because residence is the condition the whole thing rests on. This is also the only stage where a tradução juramentada appears — a sworn translation by a publicly commissioned translator or by a consulate inside Brazil. Licenses from Portuguese-speaking countries need authentication instead. A CPF, the taxpayer number that gates most Brazilian paperwork, is on the list too: what a CPF is and how a foreigner gets one.

If your license is Spanish, Italian or Mozambican, a bilateral agreement outranks the resolution — and, against expectation, makes the process slower. Detran-RJ warns that these files need clearance from the national traffic secretariat, and Spanish or Italian licenses need clearance from the issuing country's own authority as well. The waiver has limits: the Spain agreement still requires written and on-road tests for the heavy categories, and the Italy agreement drops the tests only for a holder resident in Brazil under four years.

What we could not verify

• Whether the 180 days restart after you leave and return. Reading the full resolution on 27 August 2026, the phrases for a new entry and for leaving the territory appear zero times, and the two occurrences of "reinic" concern a learner's file. The tension between "date of entry" and "regular stay" is in the text; the text does not settle it.
• Which item of the code an officer writes up for a foreign license past its deadline. No enforcement guidance from the national traffic secretariat came up in our search, and we will not guess at it.
• Whether any later resolution has amended 1,020/2025. The ministry's resolution index and the gazette search both assemble in JavaScript, so we could not sweep them. Other routes turned up no amendment — a weak negative, and we treat it as one.
• What the two assessments actually cost in each state. We have the national ceiling and one state authority saying its own contracts still govern. We did not survey the other 26.
• Whether the appeal court later ruled on the merits behind the December 2025 injunction. We have the 23 December decision restoring the resolution, and did not follow the case file past it.
