Blind Crest Signs

What are they?

Blind CrestThe "Blind Crest" sign is a warning sign which may be erected to advise motorists of a section of roadway that due to its vertical alignment causes an unusual degree of hazard.

Where are they used?

"Blind Crest" signs may be used on roadways where the visibility of the motorist is restricted by the vertical alignment and where stopping sight distance is inadequate due to prevailing operating speeds.The signs are most commonly used on roadways having significant volumes of traffic and higher operating speeds which combined with the alignment constitute a hazard to the motorist. This would include rural highways, collector and arterial roadways.

Generally, we do not install "Blind Crest" signs within residential areas where volumes and speeds are both relatively low and the majority of traffic is familiar with the characteristics of the street system.
