Government agencies continue to recognize the important correlation between the retroreflectivity of roadway signs and roadway safety. There are millions of signs on our roadways and they all play a vital role in keeping motorists safe. While all roadway signs are important, some are of more importance than others and need to be emphasized.

Visually enhance traffic signs that require high-emphasis including:

  • Mid-block pedestrian crossings
  • School crossings
  • Highway entrance ramps
  • Highway exit ramps
  • Intersection median noses
  • Round-about entrances
  • Sharp curves
  • High-risk intersections
  • Signs that are installed extraordinarily close or far from the travel-way
  • Make traffic signs noticeable that are close to the travel-way, but are not facing the direction of travel
