== Keep instruction ==
"Keep" or "stay to the left/right" instructions should be given where it is unclear how to continue on the highway on which one is driving. This is the classic use case for wayfinders.
=== Criteria ===
A wayfinder An instruction should be given where it is unclear how to give continue on the highway on which one is driving. Usually this is a "keep" instruction on , but sometimes, as explained [[#Continue instruction|below]], it should be a continuation continue instruction. A wayfinder is warranted in the following cases:
*The continuation path on a controlled-access highway or freeway, when an exit is present on the right side, has at least two fewer ''travel lanes'' after the exit than before it;
*The continuation path on a controlled-access highway or freeway has the same number of lanes as, or fewer lanes than, the exit path after the fork;
In these cases, we need to use a wayfinder configuration. Each wayfinder configuration will have one "IN" segment and two "OUT" segments.
==== Configuration ====
* Each "stub" segment should be {{:Segment length/Minimum}} long. This is long enough so it will not cause routing problems, but it is short enough to suppress display of the names (on Freeway stubs) and keep freeways looking contiguous (on Ramp stubs).

=== Continue instruction ===With the creation of turn instruction overrides, continue instructions can be given . Where a keep or exit instruction would be misleading, a continue instruction can be given, as explained [[Turn_instruction_override#Supplement_a_wayfinder|here]]. The [[turn instruction override]] page also has other use cases for the continue instruction on highways, most of which are not wayfinders (i.e. Generally these are given where it is clear how to continue on the highway, but an instruction is nonetheless useful). Where a continue instruction is used to supplement a wayfinder, the geometry should match the instruction is otherwise beneficial, so the highway should not deviate=== Criteria === === Configuration ===
