Indeed hour_on=*, *et. al.* were deprecated as being ambiguous for all but the simplest use cases (which is also why opening_hours=* was created for POIs). I'd be willing to go with effective_hours=*, using the same format as opening_hours=* if that sounds alright, and update the relevant pages as appropriate. The hours in question would represent the the time frame in which the restriction applies. For example, 36th and Harvard in Tulsa: http://www.mapillary.com/map/im/thEPKkBiTOgqG3GwEoUieA/photo The sign reads "No left turn Mon-Sat 7AM-7PM". type=restriction restriction=no_left_turn effective_hours=Mo-Sa 07:00-19:00 A more complex example can be found at 11th and Denver: http://www.mapillary.com/map/im/iSaY1yIcDNfkt8lCfeaoOA/photo The sign reads "no left turn 7:30-8:30AM, 4:15-5:30PM except MTTA busses". type=restriction restriction=no_left_turn effective_hours=7:30-8:30,16:15-17:30 except=bus except:operator=Metropolitan Tulsa Transit Authority Granted, this is a weird one, since I'm not clear if this would be a boolean OR or AND situation, AND would be what it is, but it might be interpreted as OR (ie, any MTTA vehicle, OR any bus; rather than "any bus operated by MTTA"). We're also leaving out that while they're technically not supposed to, MTTA maintenance vehicles, MTTA tow trucks and MTTA supervisors also make the left turn there without so much as a second glance from the traffic cops (arguably it's better to get the busses moving again faster than make nonrevenue vehicles associated with the agency go around and keep traffic on Denver flowing, so dinging these guys on a technicality would go against the spirit of the law). > But as far as I know there is no OSM routing engine that supports > conditional restrictions yet, whatever the tag.

That said, this is a tagging issue first and foremost, and I believe effective_hours=* would be an elegant solution. Thoughts?
