To filter the map so that it only displays vehicles and drivers with a specific tag:
From the Main section of the navigation bar choose Map to open the Map screen.
In the Filter Vehicles field, enter the text "tag:[tag name]".
The map filters out all vehicles and drivers that do not have the tag, and displays only the vehicles and drivers that do have the tag.
The text beside the Filter Vehicles field indicates how many vehicles with the specific tag are displayed on the map:
If you only want to filter on vehicles or drivers that have the tag assigned, use the text "vehicle.tag:" or "driver.tag:" instead of "tag:".
