Diamond-shaped signs signify warnings.Rectangular signs with the longer direction horizontalprovide guidance information.Pentagons indicate schoolzones.A circular sign warns of a railroad crossing.  \nThe illustration below shows how the shape andcolor of a sign indicate the nature of the message.  \n# ●REGULATORYWARNINGGUIDESERVICES\n\nCONSTRUCTIONRECREATION  \nTest your Sign IQ by taking the interactiveshape and color quiz available on the web athttp://mutcd.fhwa.dot.gov.
