Retroreflective Yellow-green School Signs and Post Covers
Comparison between standard yellow school warning sign and the retroreflective sign with a retroreflective post cover.
High-visibility signing, often in retroreflective yellow-green color, can draw a driver’s attention. The MUTCD allows the retroreflective yellow-green color to be used for nonmotor vehicle warning signs instead of yellow. Many communities are selecting to use high-visibility signing only in their school zones to make the school crossings stand out. The context of the school area should be understood when considering these types of signs. One guideline is that if retroreflective yellow-green signs are used, this color should be installed consistently throughout the school zone and not mixed with signs of the standard yellow school warning color.
Retroreflective yellow-green covers can also be applied to sign posts to draw the driver’s attention to the sign. The retroreflective yellow-green post covers can have the SCHOOL legend printed on them.
