Status: de facto

Legal access restriction for vehicles that exceed the specified weight, especially useful on bridge segments (tagged with bridge=*). Metric tonnes are a default unit, other units must be explicitly tagged.

Usage

Add the tag to a way or area.

If a unit is not specified, the value is assumed to be in tonnes (British English, 'metric tons' in American English). You must explicitly specify the unit if it is not in metric tonnes. See page Units for possible units and format.

In Texas, the weight given on signs is almost always expressed in pounds, abbreviated as "lbs", which should be tagged as maxweight=### lbs. [2] In the rest of the United States, with the exception of the "empty weight" sign (see below), the weight is always expressed in short tons, abbreviated either as "tons" or "T", which should be tagged as maxweight=### st.

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

Lookalikes

Caution, pitfall! The signs below are not weight restrictions, but rather restrictions for goods vehicles with a maximum allowed weight above the depicted value, or max weight per axle not per vehicle.

See more examples at Key:maxweightrating and Key:maxaxleload pages.

Tagging history

In past mappers in USA converted short tons to pounds ("lbs" unit) rather than use "st" unit. As result there are some "lbs" units used in USA despite that signs use rather short ton unit[2].

The NCUTCD has recommended that a future MUTCD standard "Clarify that the single-unit truck silhouette shown in the R12-5 sign shall apply to all single unit vehicles, regardless of the number of axles or shape of vehicle." [1] As of 2019, this recommendation about the single-unit truck symbol has not yet been incorporated into the MUTCD or any state MUTCD, but see the meeting minutes for several state variations on MUTCD R12-5 that express clearer limits than the current national standard.
