Knowing the work zone signs—and driving according to what they tell you—is the first step in motoring safely through roadway construction, maintenance and utility sites. By “signs” we mean more than just the orange metal plaques. Our definition includes all the temporary traffic control devices—cones, drums, barricades, barriers, warning lights, signals, arrow boards, message signs, and pavement markings. Whether they are placed on, over or next to a street, road or highway, they serve to warn, regulate and guide you through work zones.
Take this short quiz to test your knowledge of signs and other temporary traffic control devices in roadway work zones. You may learn a few new things about signs and devices, including how they help you navigate safely through these challenging sites.
