South Korea on a Brazilian Licence — IDP Required, and Your Lei Seca Habit Helps

For a Brazilian driver, South Korea swaps chaotic-but-familiar traffic for fast, orderly, sign-dense city driving. The good news: two of the things that trip up most visitors are already second nature to you. The catch is a single document.

The verdict for Brazilian licence holders

Your Brazilian licence is not valid on its own in South Korea. You need an International Driving Permit issued under the 1949 Geneva Convention, carried with your licence and passport. It is valid for one year from the date of entry. You must arrange it in Brazil before flying — Korea does not issue it, and no rental company will release a car without it. This is the step that catches Brazilians out, so do not leave it to the airport.

What carries over from home

Both Brazil and South Korea drive on the right, so there is no side switch — one less thing to relearn. And here is the part that genuinely helps: Brazil’s Lei Seca enforces effective zero tolerance on alcohol, far below Korea’s already-strict 0.03 BAC. Where other visitors have to tighten their habits, yours already exceed the local rule. Keep doing exactly what you do at home: nothing before you drive.

The real adjustment: signs and city pace

The hard part is navigation. Korean hangeul signage dominates once you leave the main expressways, and Seoul’s traffic is fast and assertive with loose lane discipline. Set offline maps in a language you read before you pull away, and give yourself room — aggressive merging is normal, not personal.

Speeds and practicalities

Limits run 110 km/h on expressways, 80 rural and 50 in towns. Fuel is around $1.42/litre, the emergency number is 112, and a basic speeding penalty starts near KRW 30,000 (≈ €20) — but the camera network is dense, so they accumulate fast.
