Seoul Subway Seat Etiquette: Priority Seats, Pink Seats and the Rules Nobody Tells You

Korean subway etiquette is almost entirely unwritten, which makes it hard to learn and easy to violate. There is no sign that says “do not do this”, because everyone already knows. Here is what everyone already knows, and, just as usefully, what is actually against the rules.

Which seats are which?

🪑 Seat types on a Seoul subway car

The formal legal name for the yellow seats is 교통약자석 (gyotong-yakja-seok), “seat for the mobility-vulnerable”, under the Act on Promotion of Transportation Convenience for Mobility Disadvantaged Persons, which requires that at least one tenth of rail carriage capacity be designated this way. Under that law, the category covers not only older passengers but people with disabilities, pregnant passengers, people carrying infants and the injured.

Almost nobody uses that term. In conversation the seats are 노약자석 (noyakja-seok), the seat for the old and weak, a leftover from when they were called elderly courtesy seats. Korean commentators have argued for years that the colloquial name is the root of the problem, because it recasts a shared facility for several groups as an age entitlement.

So can I sit in a priority seat or not?

Legally, yes. Socially, the picture is different, and the reason is demographic rather than cultural.

Korea crossed the UN threshold for a super-aged society in 2025, with people aged 65 and over passing 20% of the population. Seoul itself crossed 20% around July 2025. When free subway travel for over-65s was introduced in 1984, that age group was about 4% of the population. It is now over a fifth, riding a network with the same three-plus-three seats at the end of each car that it had then.

The friction this produces is real. In September 2026 a dispute on Line 2 between an older passenger and a woman who did not give up her seat escalated into a physical scuffle, with the man grabbing her collar and the woman kicking out. That is not a typical ride. It is also not a one-off, and it is why most Koreans under sixty simply do not sit in the yellow seats at all, even on an empty midnight train.

The practical reading: if the car is empty, sitting there is fine and common. If anyone who might plausibly want the seat boards, get up immediately and without being asked. If that calculation feels stressful, just sit somewhere else.

Why is free travel part of this story?

Because it is the reason the network is full of older riders and the reason the operator cannot afford to add cars.

Free travel for over-65s began as a 50% discount for over-70s in 1980, was extended to 65 and over by the 1981 Elderly Welfare Act, and became a full exemption by presidential instruction in 1984. Foreign permanent residents were included from 2013.

In March 2026 the president instructed officials to examine restricting free travel during peak hours, prompting immediate opposition from thirteen senior citizens’ organisations who called it a matter of survival. Seoul has separately floated raising the qualifying age from 65 to 70. Neither change has been made, and the seats keep filling.

Why do the pink seats stay empty?

Because the whole design assumes they will. Seoul introduced two pregnancy seats per car in 2013, and the convention is that they stay vacant so that a pregnant passenger never has to ask. Early pregnancy is invisible, and asking is exactly the friction the seat exists to remove.

It works less well than it should. In one sampled survey of 136 pink seats, a pregnant passenger was sitting in 0.7% of them; non-pregnant women occupied 61.8%, men 19.9%, and 17.6% were empty. Complaints to Seoul Metro about the seats ran to 7,334 in 2022 and 7,086 in 2023.

A 2024 survey found around 70% of pregnant respondents said they had not been offered a pregnancy seat when they needed one, while 73.1% of the general public agreed the seats should be kept empty. A 2025 follow-up found 83% of the public said they had given way, against 56% of pregnant women who felt they had received it. The gap between what people believe and what people do is the entire story of this seat.

What about the pregnancy badge?

The badge, 임산부 배지 (imsanbu baeji), is issued at station customer safety offices and public health centres on presentation of a pregnancy confirmation document. In the 2024 survey, 67% of badge wearers reported having received consideration while wearing it, so it does measurably help.

There is no law that makes the badge a licence, and no law punishing misuse, although legal commentators note that obtaining a benefit under a false claim could in principle be treated as fraud. Whether foreign medical documentation is accepted for issuance is not published anywhere we could find, so if you need one, ask at a station office rather than assuming.

What actually carries a fine?

This is the part most etiquette guides get backwards. Korea polices safety, not manners.

⚖️ Prohibited acts under the Railroad Safety Act, and what is not

Eating is the surprising one. The transport ministry has explained that it was not made a prohibited act because, unlike smoking, there is no established public consensus linking it to operational safety. Seoul Metro’s conditions of carriage only bar carrying items that are unclean or give off offensive odours, which covers the durian scenario and not the lunchbox one. City buses in Seoul did ban food and drink by ordinance in 2018, which is why Koreans regularly ask why the subway did not follow.

The complaints keep coming anyway: roughly 4,197 complaints about drinking and eating on Seoul trains over five years to early 2025, at around 620 to 1,000 a year. A widely shared October 2025 photograph of passengers eating bossam and drinking makgeolli on Line 2 is the kind of incident that drives the number.

How does Korea compare with its neighbours?

Almost exactly inverted.

🌏 Seat conventions and food rules across Asian metros

Korea is the outlier that enforces seats through shame and food through nothing at all. Its neighbours do the reverse.

The rules that are not about seats

Korean has dedicated slang for the last one: 쩍벌남 (jjeokbeol-nam), roughly “manspreader”. The existence of the word tells you how closely it is watched.

What about step-free access?

Worth knowing if you are travelling with a suitcase, a pushchair or a mobility aid: Seoul finished the job at the end of 2025.

The campaign began with a death. In 2001 an elderly couple fell from a wheelchair lift at Oido Station on Line 4 and the wife was killed, following earlier lift accidents at Hyehwa in 1999 and Cheonho. The case became the founding moment of Korea’s disability mobility rights movement. Successive target dates for full lift coverage came and went; as of April 2024, lifts were installed at 99.7% of stations but only 96.1% had a complete step-free route.

On 29 December 2025, with the completion of Kkachisan Station on Line 5, Seoul reached 100% single-route step-free access across all 338 stations on eleven lines, after 175.1 billion won invested over eighteen years. In practice that means you can now get from street to platform by lift at any Seoul station without asking anyone for help.

Is any of this enforced?

The manners, almost never. Seoul Metro’s official line on priority seats is encouragement, not prohibition. There is no inspector, no fine, no penalty written into the fare rules for any of the seat behaviours above.

What there is instead is a very dense city where nearly seven million people a day share the same cars, on a network where crowding above 150% now affects 319 sections, and a set of conventions that keeps that workable. Following them costs you nothing. Ignoring them is legal, and will still make your ride worse.
