I have seen some tight intersections, with buildings directly adjoining the roadway at all four corners, where a "maxlength" tag would also be useful. A passenger car or a delivery truck would be able to turn the corner, but a tractor-trailer rig (heavy goods vehicle) or bus would get wedged in

I believe the solution for the problem has already been mentioned: the used tag "maxspeed:advisory"=* seems a good way to make the distinction between actual maxspeeds and advisory maxspeeds: http://taginfo.osm.org/keys/maxspeed%3Aadvisory#values Let's document this in the wiki, e.g. here: http://

Re: [Tagging] Maxspeed

In Australia as well they are advisory so are therefore not speed limits. You can not be fined for exceeding the advisory signs. The speed limit, and therefore maxspeed, is sign posted with a sign like this: http://upload.wikimedia.org/wikipedia/commons/3/36/Australian_60kmh_speed_limit_sign

How do you tag speed limits on curves and highway on/off ramps? At least in Ontario, these speed limits are advisory only and signed with a yellow sign (and sometimes on curves you will see a curve speed limit sign and a higher general speed limit sign right beside each other).

I like maxspeed:variable=* simply because it lets you use maxspeed=* in its original sense. Maxspeed=signals robs you of that original tag and routers now have to dig deep into tags to understand the real maxspeed. Keep the simple tags, and build around them, that's what I say. Janko. Dana 19. 12

The lowest variable speed limit I have seen on a UK motorway is 40 mph, but that doesn't mean it can't go lower. I do not believe that there is a defined minimum on motorways, rather it is up to the discretion of the police, I'd they deem you are going to slowly they will escort you off. Phil
