== Imperial unit conversion ==
As per [[Map Features/Units|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

Legal access restriction for vehicles that exceed the specified weight in metric tonnes.

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.

Examples

with signs around the world:

Switzerland Germany Korea

maxweight=5.5

Please note the dot as decimal separator.

Brasil Finland Mexico Quebec in Canada Singapore

maxweight=*

(The same sign in a few different countries)

MUTCD (United States) In the United States, the weight given on signs is always in short tons. You must explicitly specify the unit if it is not in metric tonnes:

maxweight=10 st

United Kingdom Germany

Caution, pitfall! This is not a weight restriction, but a restriction for goods vehicles with a maximum allowed weight above the depicted value!
