Hidden dip ahead
A red triangle showing a dipped road profile warns of a sudden valley in the road that's hidden from view at normal driving distance. Slow down — you can't see oncoming vehicles in the dip, you can't see pedestrians or animals on the carriageway, and the suspension will get a workout if you hit it at speed.

Where you'll see this sign
Country lanes, undulating B roads, and farmland tracks where the road follows natural terrain rather than being levelled.
