Legal access restriction for vehicles with aabove the specified weight in metric tonnes.
The maximum allowed weight, also known as the gross vehicle weight rating (GVWR), gross vehicle mass (GVM), Permissible maximum mass or max gross weight (MGW) is the maximum permitted weight of the vehicle at full load, as specified by the manufacturer. For example, in most countries,are defined as goods vehicles with a GVWR above 3.5 tonnes.
Note: for restrictions based on the actual weight see maxweight=*
Vienna Convention on Road Traffic (Nov 8, 1968)
This property relates to Chapter 1, Art. 1 (w) Permissible maximum mass means the maximum mass of the laden vehicle declared permissible by the competent authority of the State in which the vehicle is registered;
Difference to maxweight=*
The definition may be confusing, but it is really rather simple. Here is an example:
Sign Tag Meaning maxweight=5.5 Vehicles that currently weigh above 5.5t are prohibited on this road. maxweightrating:hgv=5.5 Lorries that are legally permitted to weigh more than 5.5t are prohibited on this road.
So the latter sign is a more precise way for the road traffic authority to say that access for "big lorries" is prohibited and has nothing to do with the vehicle's current actual weight. A similar mechanism is the "Unladen mass" (Chap. 1, Art. 1 (x) Vienna Convention on Road Traffic), e.g. in the United States the "empty weight" restriction, for which maxunladenweight=* has been proposed.
For example, an empty truck that weighs 5t and can carry 10t has
- current weight of 5t
- max permitted weight of 15t
with signs around the world:
maxweightrating:hgv=5.5 (use dot as a separator in the tag)
maxweightrating:hgv=7.5 (use dot as a separator in the tag)
Southern African Development Community:
maxweightrating:bus=7.5 (use dot as a separator in the tag)
- unless specified otherwise value defaults to 3.5 tons, technically maxweightrating:hgv=3.5 may be used but meaning of hgv=no is the same and that tagging is simpler - in Poland, like most countries trucks are defined as goods vehicles with maximum allowed weight above 3.5 tonnes.
- Sign that prohibits vehicles intended for/or carrying goods. Additionally, a sign may be present prohibiting vehicles whose laden mass is higher than the mass indicated on the sign. In that case, use: goods:conditional=no @ (weight>*) and hgv:conditional=no @ (weight>*)
