The legibility of highway signs is an important aspect of the driving task. Recognizing this, the Roadway Lighting Committee in the early 1970's prepared recommendations that would provide a uniform means of lighting signs so that the message and sign shapes and color will appear the same, night or day. This recommended practice is a revision and expansion of that report, "Roadway Sign illumination," published in October 1974.
