Essential 'Driving Rules' in Korea
1. U-turns: Only at Signs
You can only U-turn where you see the blue U-turn sign.
* You must wait until your car reaches the white dashed line. U-turning on a solid white/yellow line is a major violation.
* Follow the text under the sign. Common ones: "On Left Turn" (좌회전 시), "On Red Light" (보행신호 시), or "When U-turn Signal is on."
2. Right Turn on Red: Stop First
If the main light is RED, you must come to a COMPLETE STOP before the crosswalk.
* If a pedestrian is crossing, or even waiting to cross,you must stay stopped until they reach the sidewalk.
* If there is a specific arrow signal for right turns, you must wait for it.
3. School Zones (Yellow Zones)
Strictly 30km/h (some are 20km/h).
* All fines and penalty points are doubled in these zones.
* Cameras trigger even at 1km/h over the limit. Accidents involving children here carry severe criminal penalties (Minsigi Law).
4. Blue Bus Lanes (Bus Only)
* Blue Solid Line: 24-hour bus only lane. Stay out.
* Blue Dashed Line: Restricted hours (usually 07:00–21:00). Outside these hours, cars can enter.
* Automated cameras are everywhere; fines are issued instantly.
5. Highway Lane 1: Passing Only
The leftmost lane (Lane 1) on highways is for passing only.
* Cruising in Lane 1 without passing is a fineable offense. Move to Lane 2 once you've finished overtaking.
6. Zero Tolerance for DUI
0.03% BAC (Blood Alcohol Content). Essentially, one drink puts you over the legal limit.
* Use "Daeri-unjeon" (Designated Driver) services via Kakao T or T-map apps. It is cheap and safer than a criminal record.
7. Dashcams are Everywhere
Almost 99% of cars in Korea have "Blackboxes" (Dashcams).
* Citizens can report your traffic violations via the "Safety Report" (안전신문고) app using their dashcam footage. You will receive the fine in the mail.
