路面凹陷标志
MUTCD W8-2
前方路面有凹陷,请减速。
标志外观
A yellow diamond-shaped warning sign with a black symbol or the word DIP showing a sharp downward drop in the pavement.
什么时候会见到
On rural and secondary roads ahead of a short, abrupt low spot in the pavement, often where the road dips through a drainage channel or gully.
该怎么做
Slow down before you reach the dip so you keep control and avoid bottoming out; watch for water pooling in the low spot during rain.
