What does the following safety sign mean?
💡 Hint
Slope signs tell uphill from downhill by the direction of the slope line and the arrow (Enforcement Rule, Appendix 6). Work out whether the lines in the picture show bumps in the road surface, the incline of the road, or a drop-off at the road's edge.
Answer: ②
Explanation
This sign, showing a slope rising from lower left to upper right with an upward arrow and the gradient (%), is a caution sign warning of an uphill slope (Enforcement Rule, Appendix 6, No. 116). It is placed on the right side of the road 30-200 meters before the uphill section begins, and repeated midway when the slope is long. A downhill slope has a separate sign with a downward arrow.
