Here's an example with Italian signs: https://www.sicurauto.it/upload/news_/8684/img/2038-cartelli-sperimentali-pneumatici-invernali.png It says where it applies and when and says: either winter tyres or non-skid chain. Here's another one without temporal qualifiers: http://www.rmastri.it/plugins/image_gallery/images/gallery/87777194ca9513d72ed09adb11f0f3af.jpg This is the German sign for obligatory non-skid chains: https://www.avd.de/fileadmin/content/Bilder/Unterseiten/Recht/Content/Verkehrszeichen-268.png According to administrative regulations, it may only be present at times where the chains are required. It doesn't apply to motorbikes or bicycles and it also implies a speed limit of 50kph. In some countries there are default requirements for M+S tyres, in others there aren't or are based on actual conditions. There's a nice summary for Europe here (in German ;-) ): https://www.avd.de/wissen/recht/verkehrsvorschriften-ausland/winterreifenpflicht/ This is something that likely falls under the "do not map the legal situation without supporting real life objects" ban. Those sign-posted prescriptions above don't (IMHO). Cheers, Martin
