How to say 'One Way' in Korean?

When you drive in Seoul you often see 'One Way' sign printed on the road.

The Korean word on the 'One Way' sign is '일방통행' and it is a compound hanja word.

일방 means 'one side/direction' or 'one way', and 통행 means 'passage' or 'transit/traffic'. 

So, 일방통행 basically means 'one way traffic.' in Korean.

I don't think that I ever saw a 'Wrong Way' sign in Korea.

Instead, I see 'No Entry' sign for the 'Wrong Way' situation.

'No Entry' sign is written as '진입금지', where

진입 means 'entry' or 'penetration' and 금지 means 'prohibition' or 'ban' in Korean.

Together 진입금지 means 'entering is prohibited' or just 'Do Not Enter!'
