In short
- Tourists need a 1949 Geneva-Convention IDP + home licence (get the IDP before you fly — it can't be issued in Korea). Residents with an ARC need a Korean licence — an IDP isn't valid for you.
- Economy cars run ~₩40,000–90,000/day (peak Jeju summer higher). A credit card is mandatory; take the full insurance (CDW/Super CDW) — Korean firms won't accept your foreign card's coverage instead.
- Book via Klook, Trip.com, or aggregators — big Western sites (Expedia/Booking) often don't list Korean agencies like Lotte/SK.
- Drive on the right, speed cameras everywhere (your nav beeps), 0.03% BAC limit, and use Naver Map/Kakao Navi — never Google Maps.
Korea's trains and buses are so good you rarely need a car — but for Jeju, the coast, and scattered countryside spots, a rental unlocks everything. Here's how to do it legally and cheaply. See also driving in Korea (rules, licence conversion) and navigation apps.
Can you rent? (the key rule)
- Tourist / short-term: valid home licence + IDP (1949 Geneva Convention), issued in the same country as your licence, obtained before arrival. Must be 21+ with 1+ year driving experience (some SUVs/vans require 26+).
- Resident with ARC: an IDP is technically not valid — you need a Korean licence (converted or tested). Some desks may not know this, but if you crash without the correct licence you may not be covered.
- IDP caveats: Korea recognizes 1949 Geneva permits; some 1968 Vienna IDPs (Germany, France, Thailand) may be rejected by rental firms — check first. IDPs from China/Indonesia/Taiwan aren't accepted.
- ID: passport for tourists; ARC for residents (no passport needed for domestic travel, including mainland↔Jeju).
Costs & booking
- Daily rate: compact ~₩40,000–90,000 (cheapest ~Nov/Apr; Jeju in Jul–Aug can top ₩100,000). Fuel and tolls extra.
- Insurance: basic liability is included, but add CDW + Super CDW (~₩15,000–45,000/day) to cut your deductible (면책금). For foreigners this is effectively mandatory — you can't decline it citing a foreign card.
- Book on Klook / Trip.com / KAYAK or agency sites (Lotte, SK). Aggregators may show low prices excluding insurance — check the all-in total. One-way (e.g. Seoul→Jeju Airport) adds a surcharge.
- Payment: a credit card in the driver's name is required — cash/debit usually not accepted at the desk.
On the road
- Drive on the right, wheel on the left (like the US/EU). Limits: ~30 (school zones) / 50–60 (urban) / 80 (multi-lane) / 100–110 (expressway) km/h.
- Speed cameras are everywhere and tickets follow you to the rental company — your nav app warns you; heed it.
- Alcohol limit is 0.03% BAC — effectively zero. Don't drink and drive.
- Tolls: get a Hi-Pass card (from a convenience store, top up with cash) for the blue automated lanes, or use cash/card lanes. Seoul→Busan is ~₩30,900. Jeju has no expressway tolls.
- Child seats are legally required under age 6 — reserve one in advance. One additional driver can usually be added (both present at pickup).
- Navigate with Naver Map or Kakao Navi — Google Maps has no driving directions here.
Great road trips
- Jeju: the classic — a coastal ring road, beaches, waterfalls, tea fields, and Hallasan. English on major signs, easy driving. Public transport is thin once you leave the two cities, so a car is close to essential (see getting to Jeju).
- East coast: Seoul → Gangneung/Sokcho for Seoraksan and beaches (Gyeongbu/Yeongdong expressways).
- Southern loop: Gyeongju's history, Busan's coast, Tongyeong's islands.
- For a one-day taste, most day trips are doable by train/bus — save the car for regions transit can't reach well.
Common questions
Can I rent with just my home licence?
No — tourists need the IDP too; residents need a Korean licence. Bring the physical documents.
Do I have to buy the Korean insurance?
Effectively yes for foreigners — companies won't accept your foreign card's coverage in place of their CDW. Take Super CDW to minimize the deductible.
Where do I book?
Klook, Trip.com, or agency sites — the big Western platforms often don't list Korean rental companies.
Which nav app for driving?
Naver Map (CarPlay) or Kakao Navi. Not Google Maps — it can't route driving in Korea.
Sources: Lotte Rent-a-Car, KoROAD, Korea Consumer Agency (Jeju dispute data), and 2026 rental guides (DiscoverRealKorea, The Soul of Seoul, The Seoulist). IDP = 1949 Geneva; rates approximate and seasonal.
