Priority seats reserved for elderly and pregnant passengers, including specially marked pink seats for pregnancy, are customarily left empty on Korean subways and buses even when the vehicle isn't crowded and the seats would otherwise sit unused. The pink seats in particular address a real problem: early-stage pregnancy often isn't visibly apparent, so keeping the seat open by default ensures it's available for someone who needs it but might not look like they do.
There is no norm treating every first seat by the door or seats in the air-conditioned car as off-limits — those are ordinary seats used like any other, unlike the specifically designated priority and pink seating.
This etiquette reflects a broader emphasis in Korean public transit culture on visibly signaling care for vulnerable riders, and violations occasionally draw public criticism or viral social-media attention when able-bodied riders are seen occupying a clearly marked pink seat.
