The red light means empty: catching, riding, and paying for a Seoul taxi

Near midnight on a side street off Jongno, the taxis come at you as a row of small red signs floating in the dark. Each one reads the same two syllables — 빈차 (bincha), empty car — and the light is the whole conversation: lit red, the cab is yours; dark, someone already has it. You raise a hand, it drifts to the curb, you open the back door yourself and get in.

The light, and what colour the car is

The red 빈차 sign sits on the dashboard behind the windshield. When it glows, the taxi is free; once a passenger is aboard it goes dark, and a separate 예약 (yeyak), reservation, light means the car is already booked through an app and will not stop for you. At night a small roof lamp, the 갓등 (gatdeung), does the same job from a distance — lit means available.

Most Seoul cabs are a flat orange and metered the same way. The exception is the black-and-gold 모범택시 (mobeom taxi), the deluxe class: its meter starts higher — around ₩7,000 against the regular ₩4,800 — and in return you get a senior driver, more legroom, and no late-night surcharge. If you are counting won, wave the orange ones down first.

Let the app flag it for you

Standing at a curb works, but the thing that actually saves the night is 카카오 T (Kakao T), the app nearly every driver runs. You drop a pin for where you are, type or paste the destination, and the request goes out to cars nearby; a driver accepts, the plate number appears, and you watch the icon crawl toward you on the map. No Korean is spoken, and no address is mispronounced.

A call placed this way sometimes carries a small hailing fee, a few hundred to a couple of thousand won shown before you confirm, higher at peak hours. You can register a card inside the app and let it charge automatically at the end, which means the ride can begin and end without a word — useful at 2 a.m., when your pronunciation of a district name is not at its best.

What the meter does after ten

A regular Seoul cab starts at ₩4,800 for the first 1.6 kilometres, then climbs by distance and, when traffic stalls, by time. The number to plan around is the night surcharge, 심야할증 (simya haljeung): it switches on at 22:00 and is steepest between 23:00 and 02:00, when the fare runs roughly forty percent above the daytime rate. The meter folds the surcharge in on its own, so there is no separate bill to argue over.

Two habits keep the ride clean. Koreans do not tip drivers — the meter is the price, and rounding up is a courtesy, not an expectation. And if a driver already carrying a passenger slows to wave you in, that is 합승 (hapseung), shared riding; it is not standard, and you are free to decline and wait for an empty car.

Paying without a word

At the end, the reader on the console takes a tap from a credit card or a T-money (티머니) transit card — the same card you use on the subway, so one card covers train, bus, and cab. Cash works too, and the change comes back counted into your palm. If you paid inside Kakao T, nothing happens at all: you say thank you, open the door, and go.

One small thing on the way out. Open the door on the curb side and glance back for 오토바이 (otobai), the delivery motorbikes that thread the gap between the cab and the kerb. Ask for a 영수증 (yeongsujeung), a receipt, if you want the trip on record — the driver prints one from the meter in a second.

From the airport, and the one address mistake

From Incheon, a metered cab into central Seoul runs high — figure roughly ₩70,000 to ₩90,000 including the bridge toll, which the driver fronts and adds at the end, and more once the night surcharge starts. Unless you have heavy bags or land past midnight, the airport rail or the limousine bus is cheaper and often no slower; keep the taxi for the last leg from the station to the door.

The mistake that strands people is the address. Google Maps does not give proper driving directions inside Korea, and a romanised address pasted into a driver's system often lands nowhere useful. Have the destination ready in 한글 (hangeul), Korean script — a screenshot from Naver Map (네이버 지도) or a Kakao T pin does it — and the whole exchange collapses into a nod and a red light going dark as you pull away.
