wild animals

Is it ok to use hazard=wild_animals? It's not on the list, but based on Taginfo, we have 431 uses of "wild_animal" and 417 uses of "wild_animals". It's used with this road sign. maro21 22:54, 27 February 2021 (UTC)

Are you sure that isn't a deer in the picture? --ZeLonewolf (talk) 22:58, 27 February 2021 (UTC)
Yes, it is a deer, but it doesn't answer my question:) maro21 19:58, 28 February 2021 (UTC)
As you can see at the bottom of the page for the road sign, this sign is listed on the page for "hazard=animal_crossing" (section European-style signage) and also in the German and Spanish versions of this page. "hazard=wild_animal" (singular) is mainly used in some German region south of Frankfurt. "hazard=wild_animals" (plural) is used much in France in combination with "traffic_sign=FR:A15b", but together with "hazard=animal_crossing" this traffic sign tag is used more. Also in Poland there is just one combination of "traffic_sign=PL:A-18b" with "hazard=wild_animals", but there are 5 with "hazard=animal_crossing". hazard:animal=* can be used to specify the kind of animal, "hazard:animal=wild_animal" is used 169 times. "hazard=wild_animal", "hazard=wild_animals" and "hazard=deer" are listed in Tag:hazard=animal_crossing#Possible_Tagging_Mistakes. So of course you can add any tag you like, but I would rather use "hazard=animal_crossing" + "hazard:animal=wild_animal" here and adapt page Pl:Road_signs_in_Poland. --Hufkratzer (talk) 12:03, 15 August 2021 (UTC)

Coming back to the possible hazard of wild animals. I've just mapped a river crossing in Northern Australia, where you must actually drive your car through the water to cross the river, however, the rivers in this area also hold a large population of saltwater crocodiles!, & are frequently signed appropriately: eg,_Slade_Point,_2016.jpg.

This is a different problem to "hazard=animal_crossing" + "hazard:animal=wild_animal" as the danger is not that an animal may run (swim!) out in front of your vehicle, but that it may attack, & very well kill, you!

So =wild_animal/s should be included under the heading of hazards. --Fizzie41 (talk) 02:04, 10 August 2022 (UTC)


There is a traffic sign warning for a bump ahead. Is it OK to use suffix `hazard:forward=bump` or to use additional key `hazard:direction=forward` on the way? Such warning and hazard doesn't exist backward. --Plamen (talk) 12:40, 9 April 2021 (UTC)

hazard:forward=bump seems clearly better to me - follows standard scheme, not split into two tags etc Mateusz Konieczny (talk) 15:38, 9 April 2021 (UTC)
The appropriate tag for the bump is traffic_calming=bump and is not really a "hazard". Data consumers or apps can provide appropriate warning for drivers (i.e. Osmand can warn drivers about bumps or pedestrian crossings immediately ahead of the driver) --GOwin (talk) 05:57, 7 May 2021 (UTC)

covered hole


How would you tag a hole/pit that is covered by vegetation. It's not a sinkhole or a soakhole, it's just a hole that isn't noticeable until you've stepped on it and fallen in --Kylenz (talk) 23:52, 14 August 2021 (UTC)

I have documented the current use of hazard=hole --Kylenz (talk) 01:12, 20 August 2021 (UTC)

Slope, uphill and downhill

We have traffic signs that warn about dangerous or steep hill ahead, uphill or downhill. Examples: [1], [2] and [3], a few times with the incline value (e.g. incline=10%). It would be interesting to have hazard:forward|backward=uphill, hazard:forward|backward=downhill and hazard=slope (for both directions). Thank you. --IgorEliezer (talk) 18:43, 5 March 2023 (UTC)

  1. The warning should be "steep". Uphill and downhill are traveling directions. hazard=curve and hazard=curves are different, because they are not always sharp, yet require critical driver input in turning the steering wheel.
  2. hazard=slope is not clear. Slope itself is not dangerous. It is overlapping if you use *=uphill and *=downhill already. In addition, there are adverse camber warning signs for negative superelevation, cf incline:across=* for the dimension.
Besides warning, someone mentioned low gear supplementary or mandatory signs can exist together or even independently.

So is hazard=steep + incline=up|down correct for this road The downhill is from east to west as the incline is downward on the direction of the OSM way. --IgorEliezer (talk) 14:39, 2 April 2023 (UTC)

Low ceiling/ doorway

I revisited a castle today where my mother banged her head some years ago, because she didn't understand the sign "Mind your head". I'd like to add a hazard=low_ceiling or something like that. I mean, I have already, but maybe there's a better way. B-unicycling (talk) 22:22, 14 November 2023 (UTC)

Couldn't that be done with the existing Key:maxheight on the doorway or corridor in question? I'm just thinking that while it may well be a low ceiling for somebody 1.8m (6') tall, it's fine for somebody whose only 1.5m (5')! --Fizzie41 (talk) 01:34, 15 November 2023 (UTC)
That is true, but there is a sign there saying "Mind your head", and they say it to every visitor as well. I should have measured it; I had the measuring tape with me. B-unicycling (talk) 02:18, 15 November 2023 (UTC)
It would be maxheight:physical=* . Taller people are allowed in. Contrast with minheight=* where children shorter than that are prohibited.

What about hazard=tsunami for tsunami hazard zones? -- DENelson83 (talk) 06:20, 22 March 2024 (UTC)
