[Tagging] tagging no truck access in US

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.

This will simplify to live of editors, developers and data consumers. Look what was done for primaries, secondaries, etc. They don't have a different name just because the speed limit is different in each country:

fully agree, the legislation is very similar in US and Europe. just the weight limits differ. hgv is a generic term yhst we shouldn't use 3.5t. 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
