Driving in Korea opens up Jeju's coastal roads, quiet temple towns, and mountain villages that trains and buses never reach. But Korea's rules for foreign drivers are strict — and one missing document at the rental counter can end your road trip before it starts.
To rent a car in Korea, you need a physical International Driving Permit (IDP) issued under the 1949 Geneva Convention, plus your passport and your home country driver's license, all with matching names. Korea does not accept a foreign license alone or digital IDPs. The IDP is valid for up to one year from your date of entry, and most rental companies require drivers to be at least 21.

What documents do I need to rent a car in Korea?
Bring three originals to the rental counter: your passport, your home country driver's license, and a physical International Driving Permit. All three are checked together — if any one is missing, you will be refused the car.
The details matter. A photo of the IDP on your phone does not count; it must be the physical booklet. The name on all three documents must match exactly, and the IDP's "categories of vehicles" section must carry the official stamp — a blank stamp section makes the permit invalid. You also need a credit card in the driver's own name for payment and the deposit; debit cards and third-party cards are routinely refused.
How does the International Driving Permit rule work?
Korea recognizes IDPs issued under the 1949 Geneva Convention on Road Traffic (and also those under the 1968 Vienna Convention). The IDP is a standardized translation of your home license — it is never valid on its own without the original license beside it.
Which countries' IDPs are accepted?
The question is whether your IDP was issued in a country that is party to one of the two road traffic conventions. The United States, the United Kingdom, France, Australia, and most European and Asian countries issue convention-compliant IDPs that Korea accepts.
Ignore look-alike "international driving licenses" sold online — Korean rental companies do not accept them. Only a genuine IDP from an authorized body in your home country (your automobile association or licensing authority) works, and you must get it before you travel. It cannot be issued or renewed inside Korea.
How do I rent a car once I arrive?
The major companies with English-language service include Lotte Rent-a-Car, SK Rent-a-Car, and AJ Rent-a-Car, plus many smaller local companies around Jeju Airport. Rental lots are often a shuttle ride from the terminal, so allow extra time on pickup and return days.
Before driving away, photograph the car's exterior from all angles and note scratches on the rental form — two minutes that removes any damage dispute at return. Read the insurance carefully: basic coverage is usually included, but the excess can be high, and full coverage options at the counter remove most of that risk.
What are the driving rules I need to know?
Korea drives on the right, like the United States and continental Europe. Major road signs are in Korean and English, so a foreign driver is rarely lost for long.
What are the speed limits?
Limits are lower than many visitors expect, and cameras enforce them relentlessly. City streets are 50 km/h; school zones and child protection zones are 30 km/h, often camera-enforced around the clock; national and local roads run 60 to 80 km/h; expressways are generally 100 km/h, with some sections at 80 or 110 — always follow the signs.
| Road type | Typical speed limit | Notes |
|---|---|---|
| City and town streets | 50 km/h | Standard urban limit nationwide |
| School and child protection zones | 30 km/h | Camera-enforced, often around the clock |
| National and local roads | 60-80 km/h | Jeju's main roads are commonly 60 km/h |
| Expressways | 100 km/h | Some sections are 80 or 110 km/h |
A local app like Naver Map or KakaoMap warns you about cameras and speed bumps ahead; Google Maps is unreliable for driving directions in Korea.

How do highway tolls and Hi-pass work?
Most mainland expressways charge tolls through Hi-pass, an electronic system with dedicated blue-marked lanes at toll gates. Rental cars often come with a Hi-pass unit or card, and tolls are settled when you return the car. If you pass through a Hi-pass lane without the device, cameras read the license plate and the toll is charged later anyway — do not change lanes in the toll area. There are no toll roads on Jeju Island at all.

What about lanes, turns, and traffic lights?
Right turns on red are allowed after a complete stop, unless a sign forbids it. Left turns are generally prohibited except where there is a green left-turn arrow — this surprises many drivers. On expressways, keep right except to pass.
Stay out of bus-only lanes. They are marked with blue lines on city roads and red paint in Seoul's median lanes; on expressways they are reserved for buses and large vans carrying six or more people at weekends and holidays. Bus-lane tickets are one of the most common fines foreign drivers get.
Where do I park?
Parking is easy on Jeju and in smaller towns but tight in Seoul and Busan. Use paid lots and garages rather than curb parking — illegal parking is enforced, and the ticket will find you through the rental company.

Is driving in Jeju different from the mainland?
Jeju is Korea's most popular place to rent a car, and driving there is easier than on the mainland: no expressways, no tolls, far less traffic. Most visitors loop the island along the coastal roads, which are slow but scenic.
What catches visitors off guard is how slow Jeju feels. Major roads are capped at 60 km/h, 30 km/h school zones are everywhere, and speed bumps — some real, some just painted lines — are constant. Plan for journey times roughly twice what the distance suggests.

Frequently asked questions
Can I drive in Korea with only my home country license?
No. A foreign license alone is not valid in Korea. You need a physical International Driving Permit issued under the 1949 Geneva Convention (or the 1968 Vienna Convention) together with your home license and passport. Driving without a valid IDP can lead to a fine or imprisonment of up to one year.
Can I rent a car if I am under 21?
Generally no. Most rental companies require drivers to be at least 21, and some add a young-driver surcharge or restrict certain vehicle classes for drivers under 25 or 26. Check the age policy before booking, because it varies by company.
Do I need my own Hi-pass device for expressway tolls?
No. Rental cars typically come with a Hi-pass unit or card, and tolls are settled at return. If you pass through a Hi-pass lane without one, the toll is charged later by license plate. There are no toll roads on Jeju.
How strict is drunk driving enforcement in Korea?
Severe. The blood alcohol limit is 0.03 percent, lower than in many countries, and penalties are harsh. Do not drink at all if you are driving.
