When you have reached the risk zone you are asked about the status of the zone. Confirmation buttons are shown and stay visible for 5 seconds after you pass the zone location.
Select the red button if the risk zone is no longer at the location. The zone is removed from your map.
Note: If other users confirm that the zone is still on your route, then it will appear again on your map.
Select the green button to confirm that the risk zone is still at the location.
TomTom uses your report to keep the map up-to-date for all app users.
