maxweight expresses a legal weight limit for using the way to which the tag is added.

How to map

Add the tag to a way or area.

If a unit is not specified, the value is assumed to be in metric tonnes. See page Units for possible units and format.

If the restriction applies only to some classes of vehicles, way direction, lanes, or time condition, follow maxspeed#Extended_tagging.

Imperial unit conversion

As per Map Features: Units, as of September 2014 only metric units of weight (metric tonnes or kilograms) are supported for this tag. Therefore if a maxweight for a country that uses U.S. customary or Imperial measurements is desired, a conversion is required.

1 short ton (U.S. customary) = 0.90718474 metric tons
1 long ton (Imperial) = 1.0160469088 metric tons
1 pound = 0.00045359237 metric tons
1 pound = 0.453592 kilograms


Weight Tagging Remark
5 tonnes maxweight=5 Alternatively maxweight=5 t could be used.
5.5 tonnes maxweight=5.5 Please note the dot as decimal separator.
