Warning, Construction & Information SignsStandalone practice
On a local road in South Carolina, you pass a small secondary road marker that reads S-40-1234. What do the two numbers tell you?
Correct answer: 40 is the county number, and 1234 is the road number in that county.
Why
Secondary roads are local roads that serve rural and urban areas; in rural areas they are not meant as through routes. Signs for interstates, U.S. routes and state routes have different shapes and colors, which tell you the type of road. The road number helps you give your exact location in an emergency.
