What does the following safety sign mean?
💡 Hint
A triangle with a red border is a caution sign that warns of road conditions ahead (Enforcement Rule, Appendix 6). Intersection signs are told apart by which side of the main road the side road joins and whether the road ahead ends, so look carefully at the direction of the picture.
Answer: ③
Explanation
A straight road with a side road attached on its left is a caution sign warning of a ㅓ-shaped intersection (Enforcement Rule, Appendix 6, No. 105). It is placed on the right side of the road 30-120 meters before intersections with poor visibility, so slow down and watch for vehicles coming out of the side road on the left. The ㅏ-shaped sign (side road on the right) and the T-shaped sign (road ends) have different pictures.
