Hi Ben, Andrew, Graeme, Agree 100%, the hazard is the "steep descent" (or similar), which most likely (but not always) coincides with the include/gradient sign such as "15%" (and we might see "incline=-15" tag used as well).
possible tags are: hazard=Descent <-- because this is applicable to not just trucks! hazard=Steep Descent <-- because this is applicable to not just trucks! hazard:hgv=Descent hazard:hgv=Steep Descent hazard:hgv=Steep Descent;Tilting incline=-15 incline:forward=-15 <---- if you want to specify direction or is this implicit in just using incline and direction of the way anyway???? The "restriction" (assume that is the common OSM term Andrew?) or signage on the road is to use low gears. Q: Tagged on a node and/or way? What about traffic_sign:hvg=Use Low Gears traffic_sign:hvg=AU:Use Low Gears traffic_sign:hvg=Tilting traffic_sign:hvg=Use Low Gears;Tilting Feedback is most welcome Would anyone like me to create a mapillary challenge so we can tag a few of these examples?
