So what does the HC mean?
It is for trucker mainly. So when they are carrying Hazardous cargo they know which route they can and can't take. Because if a spill or a wreak happens the HazMat team can clean it up. Where the are "No HC" sighs could mean there are not HazMat teams in the area.
A road sign with the black letters "HC" inside a green circle indicates a hazardous cargo route, in other words a route which must be followed by trucks carrying hazardous cargoes. And of course, the slash makes it restricted to Hazardous Cargoes.
Red Cross Out Sign
Generally these signs are used to tell the truckers that this area is primarily a residentual area with low ability to handle a 'HazMat Situation'.
You should also see signs around larger citys advising truckers the proper routes for Hazardous Cargo.
Hope this helps.
