Which of the following statements about a road where the following safety sign is installed is NOT correct?
Where one-way signs are placed and how lanes are numbered on a one-way road (Article 16(3) of the Enforcement Rule) are each set out separately. Also consider whether the direction the sign indicates depends on whether any vehicle is coming the other way.
Answer: ④
Explanation
This sign, with an upward arrow above the words '일방통행' (one-way), indicates a one-way road on which vehicles may only proceed forward, and is installed on both sides of the road at the entrance and at necessary points along the road (Enforcement Rule Annex 6, No. 328). On a one-way road lanes are numbered from the left (Enforcement Rule Article 16(3)). Driving in the opposite direction violates the sign even if no vehicles are coming, so option 4 is wrong.
