Route Review and Published Marking Risks
Review a completed plot against TfL's four published risks: endpoints, reverse direction, directness and prohibited routes or turns.
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
endpoint review
Exam cue: Use the four public marking risks as a final checklist before submitting the route.
Concept 2
direction review
Exam cue: Review the plotted line itself, not just the route you intended to draw.
Concept 3
directness review
Concept 4
restriction review
Risk pitfalls and guardrails

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.
Correcting one detour without checking whether the edit created a new gap or restriction breach.
