using access tags on amenity=parking is common practice (mainly in a generic fashion like access=customers), it could be hgv=designated, vehicle=no for a truck only parking.
On the other hand, there is amenity =bicycle_parking and motorcycle_parking, so truck_parking would be consistent as well. I'd prefer the latter, if it's a dedicated truck parking, not sure about access or capacity (sub)tags for mixed parking (allowing "yes" as value). cheers, Martin sent from a phone _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
