The primary rule is that all 3 segments at the junction must have different names. That can be accomplished in one of two ways:
# Using road names alone - It is an easy situation if all three roads which connect have different names. If "Highway A" forks into "Highway B" and "Highway C", then that is all we need to have a properly functioning fork.
# Using signs and [[#
Wayfinder_Segments|Wayfinder Segments]] - If one of the branches of the fork has the same name as the entering segment, we must create uniqueness at the junction. If "Highway X" forks off from "Highway Y" and "Highway X" continues as the other branch, the preferred approach is to use named [[# Wayfinder_Segments|Wayfinder Segments]].
