I was kinda hoping you would, seeing as you probably remembered which ones you'd added to your proposal. Some of them are debatable as to whether or not existing tagging is adequate. Here are the ones that I think are worth considering: - Opening or swing bridge ahead - Steep hill - Trams crossing ahead - Level crossing without barrier or gate - Frail (or blind or disabled) pedestrians crossing - Pedestrians in road ahead [no sidewalk] - Overhead electric cable - Sharp deviation of route - Ice - Hidden dip I wouldn't have thought the ice hazard needed mentioning, if it weren't for the plot of a Jack Reacher novel. Some bridges can ice over sooner than the rest of the road even when icing doesn't seem much of a risk, and that may be a problem other than on bridges. Depending on climate, such a warning may be present year-round. One not covered there is the warning that a route is unsuitable for long vehicles. There are a few minor roads near me like that. Drive a long vehicle along them and (at best) you have a long reverse or (at worst) you get stuck. Also, in the UK, the sign for unexploded ordnance is the same as you have for minefields. That symbol first appeared in UK Defence Standard 05-34, Marking of Service Matériel, and was called (bizarrely) "Unexploded explosive ordnance" (if it has exploded it would no longer be explosive, and if it's explosive then it must be unexploded). In old money it would have been called "unexploded bomb." -- Paul
