The following safety sign is installed at the corner of an intersection. What is correct when entering the crossing road that this sign refers to?
💡 Hint
Where a road crosses a one-way section, a sign is placed near the intersection to show that road's direction of travel (Annex 6 of the Enforcement Rule). Think about whether only the side the arrow points to may be entered, and what it means to enter the other way.
Answer: ③
Explanation
This sign, with a straight arrow pointing left above the words '일방통행' (one-way), indicates a one-way road on which vehicles may proceed only to the left (Enforcement Rule Annex 6, No. 327). Where a road crosses the section, the sign is installed on both sides near the intersection, so on that road you may only go left, and entering the other way means driving against traffic. It does not indicate two-way traffic or a left-turn prohibition.
