Which is the correct place to install this sign?
💡 Hint
As a rule, caution signs are installed BEFORE the hazard so that drivers can prepare in advance (Enforcement Rule, Appendix 6). For placement questions, check three things one by one: before or after the point, right, left or center, and the distance range.
Answer: ②
Explanation
A picture where the divider ends at the bottom and the arrows for both directions come close again is a caution sign warning that the median strip ends (Enforcement Rule, Appendix 6, No. 124). It is placed on the median or the right side of the road 50-200 meters before the median ends. After the median ends you are closer to oncoming traffic, so be careful not to cross the centerline.
