Warning, Construction & Information SignsStandalone practice
You see this sign near an interstate exit. What does the blue color of this sign tell you?

Correct answer: It shows services, such as fuel, food, lodging or a hospital.
Why
Guide signs use color to show their purpose. Blue is for services, green is for directions and distances, and brown is for parks, historic places and other points of interest. Knowing the colors helps you find what you need without slowing traffic.
