Which payment route applies to your car
The right route depends on one thing you can check at pickup: whether the car's Hi-Pass unit has a working card. When you start the engine, the unit announces in Korean whether the card is valid. If it beeps a warning, ask the staff before you leave.
| Your car | Lane to use | How you pay | What to ask at pickup |
|---|---|---|---|
| Hi-Pass unit with a working card | Blue Hi-Pass lanes | Company bills tolls after return | Whether it adds a handling fee |
| Hi-Pass unit, card missing or invalid | Regular 일반 lanes | Card or cash at the exit | Whether they can insert a card |
| No Hi-Pass unit | Regular 일반 lanes | Card or cash at the exit | — |
Rental companies settle Hi-Pass tolls in different ways. Some bill the exact amount and some add a handling charge. No official source sets that charge, so ask at the desk and get the answer on the contract.
Driving through a Hi-Pass lane
A standard Hi-Pass lane is a narrow converted booth lane, and the government explains that its speed is limited to 30 km/h for safety. Multi-lane Hi-Pass gates remove the barriers between lanes so traffic can pass at close to normal road speed; the first on a private expressway, at Incheon Airport tollgate, is signed for 80 km/h. Follow the posted limit at each gate. The unit beeps and shows the amount as you pass.
How do you pay Korean tolls without Hi-Pass?
Some short sections near cities use open, flat-fee tollgates instead: no ticket, and a fixed charge as you pass. The Korea Expressway Corporation's fare table lists ₩800–1,100 for a passenger car at gates such as Seoul-area Daewang Pangyo, Seongnam, Cheonggye, Hanam and Gimpo.
What happens if you drive through a Hi-Pass lane by mistake?
Do not stop, reverse or swerve at the gate. The government's guidance covers the two common cases:
- You entered through a Hi-Pass lane without a working unit. At your exit, go to a staffed booth, explain, and follow the staff's instructions.
- You exited through a Hi-Pass lane without paying. The camera records the plate and registers an unpaid toll (미납통행료).
The Korea Expressway Corporation lists these ways to pay an unpaid toll:
- At the office of any tollgate
- At the information desk or payment kiosk of an expressway rest area, by card
- In the Korea Expressway Corporation's toll app, by card
- By phone on 1588-2504, using the automated card payment line from a mobile phone
Online payment at excard.co.kr requires the registered owner's digital certificate, so in a rental car that route belongs to the company, not you.
How much do Korean expressway tolls cost?
These are passenger-car (class 1) fares from the Korea Expressway Corporation's fare lookup on 23 September 2026. "Seoul tollgate" is the Seoul Tollgate near Pangyo, where most southbound trips start, not central Seoul.
| Route | Passenger car | Compact car | Distance |
|---|---|---|---|
| Seoul tollgate to Busan, fastest route | ₩18,600 | ₩9,300 | 385.8 km |
| Seoul tollgate to Busan, Gyeongbu via Gyeongju | ₩21,300 | ₩10,650 | 371.9 km |
| Seoul tollgate to Gwangju | ₩15,200 | ₩7,600 | 292.7 km |
| Seoul tollgate to Gangneung | ₩10,700 | ₩5,350 | 209.9 km |
Under Article 8 of the Toll Road Act Enforcement Decree, compact cars (경차, under 1,000 cc and within set dimensions) pay half. Electric and hydrogen cars get 30% off in 2026, falling to 20% in 2027, but only when paying with a dedicated electric-vehicle Hi-Pass card, so ask whether a rental EV's card qualifies. Privately operated expressways, including some airport and ring roads, charge more per kilometre, and your navigation app shows the expected toll before you set off.
Worked example: Seoul to Busan and back
A mid-size rental with a working Hi-Pass unit, driving the fastest route both ways, pays ₩37,200 in tolls, plus any handling charge the rental company adds. Taking the Gyeongbu route via Gyeongju both ways instead adds ₩5,400. A compact car on the fastest route pays ₩18,600 for the round trip.
