Short Route with a Road Closure
Exclude the closed road or affected movement and select the most direct valid short diversion.
From map instruction to checked route
Read the task, anchor the endpoints, remove prohibited movements, compare direct valid options and review the plotted result.
Core concepts

stated road closure
Exam cue: Remove the closed segment from consideration before comparing alternative routes.
Concept 2
blocked segment
Exam cue: A good diversion returns efficiently toward the destination without using a prohibited movement.
