I agree that it makes more sense to have a separate tag for the weight limit. I would also not be surprised to find certain roads forbidden to trucks over a certain length, or forbidding trucks with tandem trailers, because the road in question doesn't have room for a vehicle that size to turn around.

And in some countries there are 2 limits. one for small trucks and real heavy trucks ( around 7t). usually only the heavy trucks are limited. trucks above 3.5t need a different drivers license but are rarely limited for access. a tag like hgv shouldn't have a exact weight limit. instead a router can use the implicit limits defined by local legislation or aan explicit limit on signs > > Pieren > _______________________________________________ > Tagging mailing list > Tagging@openstreetmap.org > http://lists.openstreetmap.org/listinfo/tagging _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging Sent from my Verizon Wireless BlackBerry _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
