These two modifications to the federal standard – requiring ...
pavement markings at a minimum initial coefficient of retroreflective luminance of 250 mcd/m²/lux for white and 175 mcd/m²/lux for yellow. However, a new pavement marking should start at a much higher luminance to allow for degradation of the material and provide a longer duration until the minimum level of retroreflectivity is reached.
