생김새
A yellow diamond-shaped warning sign with a black symbol or the word DIP showing a sharp downward drop in the pavement.
언제 보게 되나요
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.
무엇을 해야 하나요
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.
