Guide signing is variable from one location to another because the signing must relate to the specific circumstances of a particular situation. As a result, there are many different types of guide signs for conventional highways and many different ways that these signs can be displayed.

Chapter 3 describes and illustrates the different types of conventional guide signs and how they should be displayed. The descriptions include the general purpose of each type, guidance on how it should be applied, and illustrations of how it appears. Additional descriptions and illustrations indicate how guide signs should be displayed within a guide sign assembly.
