🚌 Buses are faster than they look

Colors: blue = longer trunk, green = feeder, red = suburban express, yellow = small loop. The number matters more than the color once Naver tells you the stop.

Tap out. Rear-door exit on many routes. If you forget, you overpay. Same card as subway — T-money.

Stops are close together. Press the stop button once. Standing is normal; priority seats are real — do not camp there with a backpack.

Night buses (N-) after subway close. Slower, still cheaper than a long taxi. Pair with late night.
