Driving in Brazil with a foreign licence
The Serra do Rio do Rastro's wall of hairpins, the Chapada's red-dirt distances, Rio–Paraty's coastal jungle road: Brazil is a continent with rental counters. It runs on the 1968 rulebook with Portuguese paperwork.
Do you need one for Brazil?
Brazil (1968 convention) accepts foreign licences for 180 days — formally alongside the international permit or when the licence is readable; PRF highway police and city agents process Portuguese first, and the CNH-format expectation shapes what 'readable' means.
Brazilian enforcement is document-digital (fines to the plate, points to the driver record): when a human step involves your foreign licence, the Portuguese page prevents the creative transcription that makes later disputes exhausting.
At the rental desk
Localiza/Movida dominate with modern fleets and honest apps. Ethanol/flex fuel is standard (cheaper, fine for rentals). Book automatics ahead outside big cities. Cross-state one-ways are routine; cross-border is not.
If you're stopped
PRF highway checkpoints are professional; city blitzes check documents and alcohol (0.00% — Brazil's Lei Seca means literally dry, with breathalyzer refusal fined too). Radar is dense and marked; the marking is a courtesy, not a suggestion.
Brazil questions, straight answers
Zero alcohol — actually zero?
Actually zero: 0.0% with checkpoints outside restaurants and events (Lei Seca operations). One beer = fine + potential process. Brazilians take turns as motorista da rodada; join the system.
Rio — drive in or around?
Around. The city's traffic, tunnels and parking make apps/metro superior; collect the car leaving for Paraty/Búzios. The Rio–Santos (BR-101) coastal stretch is the reward for escaping.
Distances — what's the planning math?
Brazil is US-scale: São Paulo→Foz is 850 km of real day. Flights + regional rentals beat epic hauls; the classic loops (Sul's serras, Minas' colonial towns, Bahia's Chapada) each deserve their own pickup.
Are the radar warnings reliable?
Fixed radars are signed by law and mapped by Waze (national religion). Mobile PRF radar exists on federal highways. The system is transparent: drive the posted number and Brazil's fines never find you.
