Does cancelled mean the hazard is gone?
No. A notice may be replaced, expire or leave an in-force list. It may also be an archived message whose later outcome is unknown. Open the original warning for its cancellation reason; removal needs separate evidence.
How precise is a marker?
A marker is either a reported point or the representative centre of an area described by a warning. Open the source to see its complete geometry and wording. A warning position is not necessarily a surveyed wreck site.
What happened after a report?
Explore documented incident replays for selected accidents with dated official reports and follow-up outcomes.
