Guide signs help you find your way: where roads go, which towns are ahead and where to find services. Route signs tell you what type of road you're on.

Know the rule

Guide signs are square or rectangular and green, brown or blue. They show intersecting roads, direct you to cities and towns, and point out places of interest, hospitals, service stations, restaurants and hotels.

Know the rule

Each county has its own set of secondary road numbers. Only a few appear on the state primary map, but all are on county maps from the Department of Transportation.

Handbook p. 71 ↗

Know the rule

Secondary roads are local roads serving rural and urban traffic. In rural areas they aren't intended as through routes and normally shouldn't be used by drivers unfamiliar with the area.

Know the rule

Put it into practice

You see a marker reading S-11-17. It's a state secondary road: county number 11, road number 17. It's a local road, so if you don't know the area, stick to primary routes for through travel.
