no and I see no reasonable or useful way to do so
why? How you can verify it remotely?
(unless UK has wonderful Bing Streetside coverage)
Something like âThis SC quest is based on challenge #â and only asks to check where the segment hasnât yet been marked as correct.
As to the why, MapRoulette keeps exactly the metadata needed to know whether a maxweight has already been checked.
That you have to be able to complete the challenge remotely is news to me. Certainly helps for most challenges, but thatâs another reason for SC integration.
When the challenge has been completed, the SC quest deactivates, since we can assume that the remaining maxweight tags are correct.
ah, you propose to use MR as backend for StreetComplete rather than instead of StreetComplete

Thatâs true for a lot of Greater London, but a bit patchier elsewhere. If there were a MapRoulette challenge, the instructions would have to be clear that the user should skip if they donât have clear Bing, Mapillary, etc. imagery and canât survey it themselves.
@Mateusz_Konieczny @rskedgell @Jofban Would it be relevant to displace your discussion about the how to correct? in a subthread? This thread is mainly about the what to correct?, isnât it?

I notice StreetComplete was mentioned. This is how the max weight quest in StreetComplete looks like:
First, the user has to select a sign. In the United Kingdom, the following signs are displayed:
which are eachâŠ
maxweightmaxweightratingmaxaxleloadmaxbogieweight
The signs are supposed to look alike how the signs actually look in the country one is in currently. Especially the âmax weight ratingâ / âmax gross weightâ / MGW sign looks quite different in different countries. In UK, it is this âm g wâ thing, in Germany, within the red circle, thereâs a pictogram of a truck and below that, a white rectangular sign in which the max tonnage is specified, in most other countries it is similar to that, only that the tonnage is also given in that same sign but below the truck pictogram.
At least according to my research a few years back. Happy to add any more country-specific sign layouts, just create an issue.

The 626.1 sign is indeed indicated as a flat restriction. âVehicles or vehicles and load exceeding the weight indicated in tonnes prohibited.â Thatâs the phraseology from TSGRD 1981. However 626.1 signs are now illegal. The transitional period for them ended at the start of 2005. So if there are any of them still out there they most definitely should not be!
For the modern signs it definitely appears that the correct UK tagging should be maxweightrating for the vast majority of weak bridge et al signs and maxweightrating:hgv for the enormously common 7.5 tonne lorry restriction signs. TSGRD 2016 says âGoods vehicles exceeding the maximum gross weight indicated prohibitedâ for diagram 622.1A and âVehicles exceeding the maximum gross weight indicated prohibited from crossing the bridge or other structureâ for diagram 626.2A.
Interestingly 626.2A can have an exemption for empty vehicles appended to the bottom of the sign. I donât think thatâs widely used though.
622.1A has rather bizarre plate legends possible. TSGRD refers to â6, 8, 15, or both 8 and 15â as possible plate legends. 6 is âIceâ or âSnowdriftsâ. 8 is a time period, so restrictions only in force for part of the time. 15 refers to a smorgasboard of possibilities for exceptions including âbusesâ or âlocal busesâ; âtaxisâ; the disabled badge holder symbol, "permit holder or âpermit holdersâ, and, where appropriate, a permit identifier; âfor accessâ, âfor loadingâ, âfor loading byâ and the lorry symbol shown at item 1 of the table in Part 2 of Schedule 8, or âfor access to off-street premisesâ.
Thus weirdly (and utterly nonsensically) it would be quite legal to have a diagram 622.1A sign with âExcept for local buses and taxisâ on the plate below it!

Thereâs still a 622.1A âExcept busesâ visible in the Bing street side imagery on Station Parade, Barking. That restriction has been revoked more recently, so I didnât have to tag it.
Ah yes. That common lorry type known as a bus! Good grief thatâs stupid.
Itâd be really helpful if you could update this post so that all of the links hyperlink to pictures of the relevant sign. No-oneâs going to know what a â626.1â is

It could also be even more helpful to move this GB-centered discussion to a subtopic, as the current topic is focused on comparing the maxweight signs and meanings worldwide. 
@user_5589 @rskedgell @westnordost Isnât it? 
Well the original question was
What is the meaning of
maxweight=*in your country? Net weight or gross weight?
⊠there just came rather a lot of answers from the UK!
Thereâs at least four different discussions going on here, but they are interconnected - I donât think that it would make a huge amount of difference to split, and e.g. the Overpass queries posted in the âUK specificâ part are actually useful worldwideâŠ
What I meant is that the current topic progress gives the impression that it is now GB-centered, where it actually wasnât at the beginning, and that this could mislead people wanting to tell how the situation in their country is, by making them think that they are on the wrong topic. IMHO.
Maybe edit the topic title to say that youâre looking for contributions from lots of other countries around the world?

Seems that I canât edit the topic title anymore⊠
In general, most posted weight restrictions in the United States are about gross weight, so maxweight=* is appropriate (with st or lbs unit symbols as appropriate). A sign can optionally say âGross WTâ or âGr. Wt.â to emphasize the calculation method.
GVWR or GCWR only applies in some specific situations. For example, weigh stations divert truck traffic from the freeway based on GVWR. (Otherwise, whatâs the point of weighing them?) Most of these signs say âGVWRâ for clarity, but the ones in Maryland do not.
Colorado and Indiana also have GVWR-based speed limit and lane restriction signs.
Most of these signs actually state the vehicle weight rating above which you need a commercial driverâs license to operate the vehicle anywhere in the state. Since the requirements for a CDL vary by state, the specific numerical restriction is considered more legally defensible than a vague âcommercial vehiclesâ restriction. We donât have an established access key for commercial vehicle restrictions anyways, just an unwieldy combination of hgv=* goods=* coach=* tourist_bus=* etc.
On the other hand, California restricts commercial vehicle parking implicitly based on GVWR. This is only spelled out in the California Vehicle Code, not on the sign itself, except where the local authorities have designed their own sign.
I updated the documentation for this sign just now after this thread prompted me to look into it. Fortunately, we havenât mapped any parking restrictions based on this sign so far.

Iâve edited it - is that OK? I suspect that editing the title may mark it as âunreadâ for people too, so more people might be prompted to comment

Maybe it would be useful to start a table in the Wiki instead of the current list of examples, e.g. on Key:maxweight - OpenStreetMap Wiki
It could be simply one row per country, one column for each of the possible main tags.
Created separate thread for part of it: How to mark that `maxweight` sign is in fact actually `maxweight` rather `maxweightrating`?
Which signs denote maxweight and which maxweightrating in UK can be still answered here I hope, but I can create thread also for that
And yes, images would be great so I can check whether SC ( `maxweight` and `maxweightrating` meaning around the world - #26 by westnordost ) is broken or not

Will probably do that (if only to push a proposal to rationalize these tags, as I increasingly feels that will be necessary), but I wait for the answers here before I make it; I donât want to keep update such a table with each answer that comes here.
