A 3-minute lesson from the Wisconsin course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Blue signs point to services. Small mile markers tell you and emergency crews exactly where you are. Route markers use a different shape for each kind of road.
Know the rule
Service signs are square or rectangular, blue with white letters or symbols. They show how to get to nearby services, such as camping or a hospital.
Also called a reference marker or enhancement reference sign: a tall, thin blue or green rectangle with white lettering that shows where you are on the road.
You hit a deer on the interstate at night and call 911. Glance at the nearest small blue sign: “West, 12, Mile 216.2.” Giving that direction, route and mile number gets help to you faster.
