-There can be multiple reasons for that. Basically there are two types of access restrictions,​ permanent restrictions and temporary or conditional restrictions. When asking a machine to calculate a route, permanent restrictions are easy, it's never allowed to use the road, so don't create a route on this road. Temporary or conditional restrictions are a lot more complicated. For example a road is closed on Sundays, Kurviger cannot know if you would llike to use this road on a Sunday or not.+There can be multiple reasons for that.

The Kurviger website allows you to show these potentially closed roads as an overlay, so you can include these in your planning.

 Especially for smaller roads, there might be a missing access restriction in OSM. You should check that the access tag is set correctly. Access restrictions can be set to ways and nodes. Generally we recommend to tag the ways. Ways also include ferries, so if a ferry is not transporting motorcycles,​ this can be tagged for the way of the ferry. Especially for smaller roads, there might be a missing access restriction in OSM.

-Construction sites are not always tagged in OSM. If the construction site is only a short-term construction site (less than 6 months), the general opinion is that it's more suitable to tag it as temporary access restriction (see below). If the construction takes longer than 6 months, it should ​be tagged as permanent access restriction. [[https://​wiki.openstreetmap.org/​wiki/​Key:​construction|See the OSM wiki for more details]].+Construction sites are not always tagged in OSM.

-These can include road closures on the weekend, in the winter, at night, or for a certain period of time. This also includes construction sites shorter than 6 months. Tagging conditional access restrictions,​ might look a bit complicated at first, but don't worry, it's not that complicated,​ we will show you a couple of the common examples and should be easy to extend it for your specific case.+These can include road closures on the weekend, in the winter, at night, or for a certain period of time.

For many roads there is no fixed date, usually the road will be closed with the first snow and opened once the snow as removed in spring, so tagging no @ winter is not the worst option, but there is no way to automatically evaluate this.\\
 Some roads usually have close from a certain month to another month, so you could use ''​access:​conditional=no @ (Nov-Mar)''​ for roads that are usually close from November to March. Some roads usually have close from a certain month to another month, so you could use ''​access:​conditional=no @ (Nov-Mar)''​ for roads that are usually close from November to March.
