Costa Rica on a Brazilian Licence — No IDP Needed, but the Mountain Roads Bite

For a Brazilian driver, Costa Rica is one of the simpler Latin American countries to rent a car in — same side of the road, no special permit — but the roads themselves demand more respect than the paperwork does.

The verdict for Brazilian licence holders

You can drive in Costa Rica on your Brazilian licence with no IDP needed, for stays up to 90 days as a tourist. Your carteira nacional de habilitação plus your passport is the whole kit; the 90-day window simply tracks your entry stamp. Both countries drive on the right, so there is no side switch — you can collect the car and go.

The real adjustment: the road, not the rule book

Costa Rica’s road network is rated moderate, and the reason is geography. Outside the San José area you meet narrow mountain roads, single-lane bridges that take turns by courtesy, potholes that appear without warning, and gravel stretches to the more beautiful corners. The scenery is the payoff and the trap — drivers slow to look and forget the blind crest ahead. Treat the posted 100 km/h highway limit as a ceiling you rarely reach off the main arteries, and budget far more time than the map distance suggests. A 4x4 earns its keep in the wet season.

Alcohol: looser than you’re used to

This is the surprise for a Brazilian: Costa Rica’s 0.05 BAC limit is more lenient than Brazil’s near-zero Lei Seca standard. Don’t let the looser number change your habit — the mountain roads punish any lapse — but it does mean a glass with dinner is not the automatic offence it would be at home. Speeding penalties bite too: roughly 10 km/h over costs around CRC 53,000 (about EUR 95).

Fuel runs near USD 1.28 a litre, and the emergency number is 911. Check the full local detail on our Costa Rica driving guide, confirm your documents with the Driving Permit Checker, and size up any ticket with the Speeding Fine Calculator.
