If you’ve ever been on a crowded bus, light rail, train or subway, you know how stressful that can be. I’m sure it’s even more stressful if you’re pregnant.

Well if you’re in Busan, South Korea, there’s The Pink Light Campaign. It’s testing an alarm system that alerts anyone already occupying a priority seat that a pregnant woman has arrived and needs to sit down.

Obviously, the pro here is that pregnant women get priority seating. However, this makes me question what commuters are like.

If you see a pregnant woman entering, wouldn’t you automatically offer her your seat?

And it’s not just pregnant women. Wouldn’t you do the same if you saw an elderly person? Someone with a cane or walker? Someone with crutches? Or maybe someone who’s walking with a limp? Someone with a baby, toddler or child?

Basically, this alarm is probably a great thing for pregnant women in Busan. However no matter where you are, you should be courteous enough to offer your seat to a person of any age, shape, size and sex if they’re in need.
