If you encounter a scenario where you are coming from a Zone 30 road and see both an End of Zone 30 sign and a City Exit (CX) sign, what should you do?

In this case, both City Entrance (CE) and City Exit (CX) signs are detected in the same direction of travel. What would be the most appropriate way to mark this case?

If there is no clear “End of Zone X” sign visible in both MM and GM, it’s better to tag the area as Unknown until the next Explicit sign or until it merges with another road.


If a sign is not detected in Map Marker (MM) but is visible in Google Maps, what should we do?

We found a sign that looks like a City Entrance in the ADDITIONAL SIGNS section of the Confluence page. Should this sign be considered a City Entrance?

When entering a parking area, gas station, bus stop, or private property, the area should be considered as “Unknown.”

If a sign includes a supplementary plate (e.g., “50 m”) indicating a future change, what should be done?


A SAUF sign indicates an exception, showing which areas are not part of a Zone 30. Should we consider this kind of sign when determining the zone?
