At a crowded subway station in South Korea, most people know the unwritten rule: stand on the right side of the escalator and leave the left open for anyone in a hurry. It looks polite and efficient. But safety officials are asking whether that habit creates more problems than it solves.
Participants at a recent public forum were sharply divided. Some wanted the government to formally encourage passengers to stand on both sides. Others argued that one side should remain open, especially during rush hour. The disagreement has reopened a debate that South Korea has been having for decades.
The one-side custom did not develop by accident. Starting in 1998, public campaigns encouraged people to leave room for hurried passengers. The practice spread widely during the 2002 World Cup and became part of everyday commuter behavior.
Then accident numbers began to raise concern. Reported escalator accidents almost doubled from 44 in 2007 to 85 in 2008. Walking also puts more pressure on the equipment than standing still: a person walking down can place a load equal to about twice their body weight on an escalator, while walking up produces about one and a half times that load. When nearly everyone stands on the same side, the weight is uneven as well.
In 2009, officials changed direction and promoted standing on both sides. During the next five years, the number of reported accidents fell from 54 to 19. Yet the new advice never fully replaced the older habit. In 2015, the government stopped recommending a particular arrangement and focused instead on three basic rules: hold the handrail, do not walk or run, and remain inside the safety lines.
A recent survey of 1,000 adults shows how evenly opinion is divided. Some 50.1 percent said they normally stand on one side, while 49.9 percent said they use both sides. Among one-side users, the most common reason was to make way for people in a hurry. Among those who preferred two-line standing, safety was the main concern.
Supporters of standing on both sides say shared spaces become safer when everyone can predict what others will do. A person walking past stationary passengers can bump into them or cause a chain of falls. Standing still also reduces the sudden pressure created by footsteps and spreads weight more evenly across the machine.
But the other side of the argument is easy to understand. For commuters trying to catch a train, an open lane can save valuable time. A rule that feels safer in theory may be ignored if it does not match the reality of rush-hour travel.
The public forum did not settle the question, but it did change some minds. Before the discussion, 31.4 percent of participants supported standing on both sides. Afterward, support rose to 45.9 percent, while support for one-side standing fell from 29.9 percent to 13.4 percent. Many still preferred a flexible approach based on the location and level of crowding.
South Korea has not introduced a final new rule. For now, the safest advice remains simple: stand still, hold the handrail, and pay attention to the people around you. The larger debate is about more than choosing a side. It asks whether courtesy should be measured by the space we leave for faster travelers, or by the safety we create for everyone.
