What does the following safety sign mean?
💡 Hint
In a caution sign picture, the bottom is where you are now and the top is where you are heading (Enforcement Rule, Appendix 6). Read what structure newly appears ahead and how the arrows pass it, and do not confuse it with the railroad crossing or curved-road pictures.
Answer: ③
Explanation
A picture where a divider appears at the top and the arrows for both directions split to either side of it is a caution sign warning that a median strip begins (Enforcement Rule, Appendix 6, No. 123). It is placed on the median or the right side of the road 50-200 meters before the median begins. Stay in your lane so as not to hit the end of the divider. Priority-road, railroad-crossing, and right-curve signs have different pictures.
