What is the primary purpose of guide signs?

The principal purpose of guide signs is to direct travelers to their destinations by the best route. However, it is not feasible to install signs listing all of the possible destinations that may be reached from the highway.

Drivers must be expected to make reasonable preparation for locating their destination and to have information that is readily available on road maps.

Criteria for destinations that are permitted on guide signs can be found in the Department's Guidelines For Signing On State Trunkline Highways.
