It would just be traffic_sign=* not traffic_sign:hgv=*. My preference would be to use the exact sign number, eg. traffic_sign=AU:R6-22 traffic_sign=AU:R6-23 traffic_sign=AU:W8-201N traffic_sign=AU:W1-205 traffic_sign=AU:W1-8-2 traffic_sign=AU:W1-8-3 traffic_sign=AU:W1-8-4 traffic_sign=AU:W1-8-5 Would anyone like me to create a mapillary challenge so we can tag a few of > these examples? > Looks like Mapillary does detect some of this signage, under signs "Trucks rollover" and "Steep descent", a MapRoulette challenge would be a great idea.
