Keep right except when passing doesn't mean much in Korea. Cars, buses and particularly motorcycles and scooters pass on your right anytime they can. Whether they have to encroach on the sidewalk or not...
A note on motorcycles- they don't obey any laws unless they see a policeman ahead. They are usually delivering goods and get paid by the number of trips they make per day. You are only an irritant to them. (In the city, leave about two feet in the right lane so they can run the red light and pass you, it can save your right mirror!)When the light changes, don't accellerate immediately like you have the right-of-way! Cross traffic doesn't necessarily stop just because they see a red light!
Don't argue with a bus or truck. Let them pull in front of you. They will, anyway.
Not obeying traffic laws will get the foreigner a ticket. Seatbelt tickets and cell phone use by drivers included. On Post or off. Turn left only on green arrows, unless the blue sign (in Korean only) says unguarded left turn! Driving in a Bus Lane at any time can get your picture taken, and you may have to prove you turned out within a few meters. When a sign says camera ahead, get your speed down right now! Don't get in the express lane at a toll booth unless you have an electronic pass. You will get a ticket in the mail, or be stopped when you exit the freeway.
PARKING- don't park just anywhere in the city. Koreans pay up to $500 a year for their numbered parking areas. In parking garages and lots, don't be surprised if someone has blocked you in when you return from shopping. Someone will help you push the offending car over a space so you can get out. (They don't put them in Park when they block you.) Also note the little pillows, or signs in the drivers side window. The driver's cell phone number is printed there. Isn't that special! You might save yourself a ticket if you put your number there, too! If you frustrate easily, take a bus or subway. It is cheaper, also.
Oh yeah, if you haven't noticed, the old Japanese custom of keeping left when walking still predominates in the subway, so when walking, NEVER make a hard right at a corner, or you could get injured or break your glasses.

You forgot the Korean Brake, which is conveniently located on the steering wheel and goes "BEEEEEEEEEP! BEEEEEEEEEEEEEEEEEEP!"

That used to be the case! No longer. You can get a ticket for blowing a horn near a hospital. The horn may still be used judiciously (short beep) occasionally to remind walking Koreans that it would be nice if your car is allowed to share their road with them. They still give you a stare that says, "We were walking here 3000 years ago, so don't rush us". On narrow roads, the downhill driver has the right of way, legally. Sometimes at an impasse, it is best to just stop and smile, not gesture or yell words in English. They will eventually clear the way, although sometimes grudgingly.

I am glad to hear that!!! There sure was a lot of horn blowing when I was there a couple years ago and I was all "wth?!?!"

Wow, Joe. Thanks for the heads up! I've driven in Japan before and getting used to driving on the wrong side, er, I mean the left side of the road was difficult enough. What was worse was coming back stateside and learning how to drive normal again, LOL! Anyway, I'm bringing a small car with me when I arrive this winter so all the tips you posted were great. Thanks and keep up the great work!

LOL - That is so true. I've been honked at for not running red lights here. And I always wait to go once the light turns green or I get a green arrow.

What I do not understand is why people will run red lights, but not turn left on a green light if there isn't an arrow?

Gotcha! You may NOT turn left on a green light in Korea ! Only a GREEN ARROW! There is an exception- ONLY IF THERE IS A Little BLUE SIGN IN KOREAN, which may or may not be annotated in English "UNPROTECTED LEFT TURN"!
That means the same as left on green if the way is clear.

Right on RED is just as in the US- OK unless prohibited with a sign.

****An unprotected left turn is allowed when your signal is green and when there is sufficient clearance between you and the opposing traffic. In case of traffic conflict, however, the responsibility for signaling falls onto left-turning vehicles.****

This is a quote straight out of the drivers manual....if i'm reading it right you can turn left on a green light....

Sorry,you MUST have a sign saying unprotected left turn to use your theory. Read the book thoroughly.
There is such a sign on Yongsan, at the intersection visible coming from the Hospital to the Dragon. You can turn left when safe.
Try it where there is no such sign, off post, and you will get a ticket, or an at fault accident. Such a light is at the Noksapyong intersection. (Entering Itaewon from the Post.) We sit there through two green light changes every day, until the green arrow comes on. Memorize the sign-most are in Korean only.
