Restriction Symbols and Route Effect
Translate the map's movement or access symbols into a route-planning consequence without inventing restrictions that are not shown.
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
Concept 1
prohibited route
Exam cue: State what movement the symbol permits or prohibits before adjusting the route.
Concept 2
prohibited turn
Exam cue: Apply the restriction only to the road, direction or junction to which the map attaches it.
Concept 3
directional restriction
Concept 4
route consequence
Risk pitfalls and guardrails
Seeing a restriction but applying it to the wrong direction.
Guardrail: Do not rely on an old assessment count, atlas format or remembered London route when the current map and task supply the controlling evidence.
Avoiding an entire road when the symbol controls only one movement.
