Module 1: Retroreflection

This module has been split into different chapters to answer the question, "What is retro-reflectivity?” and how it relates to traffic signs or what drivers see. We begin with chapter 1, which introduces the basics, and build to more technical details from there. Continue learning about the science of sheeting and color in Module 2.
