In our view, driving around central Seoul isn’t worth it for most visitors. Traffic is slow, bus lanes carry camera fines, one tunnel route has its own toll booth, and parking adds up quickly. A car makes more sense when your plans lead out of the city.
This guide helps you decide, then covers the rules and costs most likely to surprise a foreign driver in Seoul. If you do drive, these are the ones to learn first.
The short answer
- Skip the car if you’re staying in central Seoul and sightseeing by day.
- Consider one if you’re heading out of the city, traveling with someone who can’t manage public transit, or carrying a lot of gear.
- Bus lanes: center lanes run 24 hours a day. Rental cars have no general permission to use them.
- Namsan tunnels: a KRW 2,000 toll applies toward downtown on weekdays from 7 a.m. to 9 p.m. if the car carries two people or fewer.
- Old city center: Seoul restricts emissions grade 5 vehicles without approved emissions work from 6 a.m. to 9 p.m. every day.
- Parking: city-run lots charge in five-minute increments, and the priciest example below works out to KRW 8,400 an hour.
When a car is worth it in Seoul
Seoul figures given to a lawmaker and reported in August 2026 put the 2025 average traffic speed at 18.0 km/h downtown and 22.5 km/h across the city (about 11 and 14 mph, our conversions). Those are averages, so individual trips will vary.
Our take: leave the car out of the central part of your trip, and rent for the days it does a job transit can’t. That usually means one of these:
- A day trip or a longer drive out of the city
- Travel with young children, older relatives or someone with limited mobility
- Bulky gear, such as camping equipment
- Late trips or stops that are awkward to reach by transit
If you’re starting in Seoul and leaving by road, try to book the car for the day you leave rather than the day you arrive. You avoid paying for parking while it sits unused. Check your hotel’s parking first, since availability and charges vary.
What you need before you drive
Our international driving permit guide covers which permits Korea accepts, and our car rental guide separates the law from each company’s own terms.
Set up navigation before you leave the rental office. Our navigation guide compares the apps to use, because Google Maps didn’t offer driving directions in Korea when we last checked.
If you live in Korea rather than visiting, our guide to converting a foreign license covers the next step.
Bus lanes: hours depend on the lane
Seoul’s published statistics describe three kinds of bus lane on city roads. Hours differ by type, so a lane that’s open to you on a Saturday may be closed to you at the next intersection.
| Lane type | Hours listed by Seoul |
|---|---|
| Center bus lane (중앙 버스전용차로) | 24 hours, every day |
| Curbside lane, full-day type (가로변 전일제) | Weekdays, 7 a.m. to 9 p.m. |
| Curbside lane, part-time type (가로변 시간제) | Weekdays, 7 to 10 a.m. and 5 to 9 p.m. |
Seoul lists curbside lanes as not operating on weekends or public holidays. These hours come from city statistics updated in 2024, and we haven’t reviewed the newest city notice, so treat the signs and road markings in front of you as the final word.
Annex 1 of the Road Traffic Act Enforcement Decree lists who may use bus lanes on ordinary roads. It covers vehicles such as large buses, certain commercial passenger vehicles and certain school, commuter and tourist vehicles. It doesn’t list ordinary rental cars. If you see another vehicle in the lane, don’t follow it, because it may be allowed there and you may not be.
On an ordinary road, the camera fine is KRW 50,000 for a passenger car and KRW 60,000 for a van. Expressways use different rules. Part of the Gyeongbu Expressway bus lane, between Yangjae and Seocho, runs inside Seoul. A vehicle there needs 9 or more seats, and a passenger car or a van with 12 seats or fewer also needs at least six people on board. We haven’t confirmed that lane’s hours, so stay out unless its signs clearly allow you. The camera fine on an expressway bus lane is KRW 90,000 for a passenger car and KRW 100,000 for a van.
Our guide to speed cameras and fines explains how camera fines reach a renter.
The Namsan tunnel toll
Namsan Tunnels 1 and 3 run under the hill in central Seoul, and they have their own congestion toll. This one is run by the city’s facilities corporation, not the expressway system covered in our highway toll guide.
Since January 15, 2024, the toll has applied only in the direction of downtown. Going toward Gangnam, you shouldn’t be charged.
| Item | What the operator says |
|---|---|
| Who pays | Passenger cars and vans of up to 10 seats with two people or fewer, driver included |
| Hours | Monday to Friday, 7 a.m. to 9 p.m. |
| Free | Saturdays, Sundays and public holidays |
| Standard toll | KRW 2,000 |
| Payment listed | Cash, transit cards including T-money, and a pre-registered auto-pay service |
Passenger cars with three or more people are exempt, as are several other groups. These include low-emission vehicles: Class 1 electric and hydrogen cars and Class 2 hybrids. Light cars (경차) such as the Kia Morning pay KRW 1,000. Slow down at the booth and confirm your passenger count or exemption with the attendant.
Hi-Pass isn’t among the payment methods listed, so don’t assume your rental car’s device will work here. Keep some cash or a T-money card handy if your route goes through either tunnel on a weekday.
If you can’t pay at the booth, the operator describes a deferred payment process: you’re given an account to pay into, or you can pay in person, within 15 days of your trip. Miss it, or drive through unpaid, and a KRW 10,000 administrative fine, toll included, applies to a standard vehicle. The operator says paying within the advance notice period cuts that to KRW 8,000, and late charges can follow if it goes unpaid. Its inquiry line is 1666-6439.
The operator also warns that the Namsan Tunnel 1 toll plaza has no U-turn lane, so don’t count on turning around once you’re committed to that approach.
The Green Transport Zone
The Green Transport Zone (녹색교통지역) covers the area inside Seoul’s old city wall. Emissions grade 5 vehicles are restricted there from 6 a.m. to 9 p.m. every day, weekends and public holidays included, unless they’ve had approved emissions work. Seoul says it enforces this through a vehicle monitoring system at 45 entry points.
Seoul lists a fine of KRW 100,000, charged once per day, rising to KRW 200,000 from the third violation. Exemptions include emergency vehicles and vehicles for people with disabilities.
Seoul’s environment department also lists a December-to-March limit on these vehicles, on weekdays from 6 a.m. to 9 p.m., with its own KRW 100,000 fine, plus limits on emergency air-quality days. That page doesn’t state the area covered, so don’t assume those limits stop at the zone boundary.
If you’re borrowing or renting an older car, ask for its emissions grade before you drive in the zone.
Parking in Seoul
Seoul Facilities Corporation publishes prices for the public lots it runs directly. These examples show the base rate for a standard car:
| Lot | Per 5 minutes | One hour (our math) | One day |
|---|---|---|---|
| Seoul Global Center | KRW 700 | KRW 8,400 | KRW 50,400 |
| Hullyeonwon Park | KRW 550 | KRW 6,600 | KRW 39,600 |
| Jamsil Station | KRW 440 | KRW 5,280 | KRW 31,600 |
| Jongmyo | KRW 400 | KRW 4,800 | KRW 28,800 |
| Dongdaemun | KRW 360 | KRW 4,320 | KRW 25,900 |
The daily rate covers 24 hours from entry, according to the operator, and vehicles that take more than one space pay more. Private lots, department stores and hotels set their own prices, so check the sign at the entrance. At the lots it runs, the operator lists credit cards, T-money and ZeroPay, but not cash.
The city’s parking information system shows lots on a map, but we found no English menu. Your navigation app may be the easier way to find a lot near your destination.
Don’t leave the car on the street to save money. Our parking guide lists the places where you can’t stop, along with fines of KRW 40,000 and up for a passenger car.
If you’re renting
Traffic fines from the rental period can follow you after you return the car. Before you leave the counter, ask these questions:
- How do you pass on bus lane, parking and congestion toll fines?
- Does this car have a Hi-Pass device, and how are its tolls charged?
- Is this car classed as a low-emission vehicle?
- What is the car’s emissions grade?
Ask for any answer that matters in writing. For a legal question, such as whether a fine was correctly issued, contact the agency named on the notice rather than the rental company. If something goes wrong on the road, our accident guide covers what to do at the scene.
Before you drive in Seoul
- Check whether your route runs through a Namsan tunnel on a weekday, and keep cash or T-money handy.
- Stay out of any lane marked for buses until you’ve read its sign.
- Plan where you’ll park before you set off.
- Ask about the car’s emissions grade if it’s an older model.
