Using the Heavy goods vehicle - fastest (Time) routing engine, draw a manual or automatic zone (see `Creating a zoning`_ section). In the right-hand panel, check the “Don’t go inside this zone” box |excludedZones| for the zone(s) to be excluded from routes. :numref:`excludedZonesPlan`
The zonings you create can be accessed from the drop-down menu alongside the Zonings field in the panel to the right of a Plan page. They can be single or multiple. :numref:`scrolldown_zoning`
If the number of routes imported is greater than the number of vehicles available, the “Tried to import more routes than available vehicles” error appears. :numref:`trying_import_more_routes_than_vehicles_error_message`
The Priority must be in the range -4 to 4. Outside that range, an error will be reported. Check that the Priority column contains a number between -4 and 4. :numref:`priority_error_message`.
