Thank you for the answers given. Perhaps there are some misunderstandings, so I want to clarify two points:
1. A HGV is defined as a vehicle with a max allowable mass of above 3.5t, even in the UK. Tagging "hgv=no" when seeing this sign is plain incorrect, except if we specifically redefine only for OSM what constitutes a HGV contrary to what can be found in the actual legislation. I don't think it is wise to do that. 2. How HGV are defined (>3.5t) and what can be seen on signs like these (7.5t) is NOT THE WEIGHT but the maximum allowed weight. This is very important. The maximum allowed weight, also known as the gross vehicle mass or GVM or GVWR is the maximum permitted weight of the vehicle at full load, as specified by the manufacturer. (See https://en.wikipedia.org/wiki/Gross_vehicle_weight_rating) Just to be clear, an example. Let's say there is a lorry with the following properties on the road: - Without any load it weighs 2 tons -> this is the unladen/empty weight - It carries 4 tons of gravel -> this is the tara/load - It currently weighs 6.5 tons -> this is the current/actual weight. Used for maxweight=* - It could load up to 7 tons -> this is the maximum capacity - It is permitted to weigh in total up to 9 tons -> this is the maximum permitted/allowed weight/mass, aka gross vehicle mass, aka GVM - in other words, GVM = unladen weight + maximum capacity Thus, using maxweight=7.5 is incorrect already because the maxweight tag is about the maximum CURRENT weight. A HGV whose permitted maximum weight is above 7.5 tons but which currently weighs below 7.5 tons is not allowed on roads signed with the linked sign. So, these are the points I wanted to clarify. Also, turns out that someone else already noticed the exact problem and created a proposal for this, which seems kind of abondoned, as usual: https://wiki.openstreetmap.org/wiki/Proposed_features/gross_weight How can we get this proposal started again? Because, the only correct way to tag the sign initially posted here would be with maxweightrating:hgv=7.5 (if the proposal is unchanged) Greetings Tobias On 26/09/2018 13:35, Tobias Zwick wrote: > Hey there > > I can't believe this didn't come up before - or maybe it did but was not > documented in the wiki. > > In United Kingdom, how do you tag roads signed with this sign? > > https://en.wikipedia.org/wiki/File:UK_traffic_sign_622.1A.svg > > Note that the GVM for which the sign applies is given explicitly on the > sign, which is apparently always the case for any HGV-access-restriction > sign in the UK. > > In other words, you will never find a sign like this in the UK: > > https://commons.wikimedia.org/wiki/File:Nederlands_verkeersbord_C7.svg > > Greetings > Tobias > > P.S: GVM is gross vehicle mass > https://en.wikipedia.org/wiki/Gross_vehicle_weight_rating > > _______________________________________________ > Talk-GB mailing list > Talk-GB@openstreetmap.org > https://lists.openstreetmap.org/listinfo/talk-gb > _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
