>the similarity with the single truck-sign<br>
<br>
Even the maxlength traffic sign is more similar with the "single truck" sign.<br>
<br>
As to tagging the este vehicle+trailer weight limits, I haven't tagged any such vehicle combination limits before. Intuitively, though, I'd go with
<br>
<br>
maxweight=50 (the limit still applies also if you don't have a trailer) +<br>
maxweight:combination=50 (or some other word, like :train)<br>
<br>

>signed the vienna convention on traffic signs<br>
<br>
I'm starting to see this convention mentioned all too often, in contexts where it has little relevance to tagging the properties of road objects in OSM. The text exists to make sure drivers can reasonably operate their vehicles abroad, not to dictate what signs
may ever be used, or the legalese behind every traffic sign one can see. Parties to the convention can introduce new signs where needed and where the text doesn't offer one "as is". Most states even made some other reservations, I haven't bothered to read
them through. <br>
<br>
Local law always supercedes that convention, and different things may (or may not) require different tags.
