[Tagging] Specifying maxweight, when different weight limits are signed

The Florida Trucking Manual [1] (page 10) explains the categories thus: 

_The maximum allowable weight is listed in tons beside the silhouette
for each of the three classes of vehicles._ 

_The SINGLE-UNIT TRUCK silhouette includes all straight trucks, cranes,
and other single-unit special mobile equipment regardless of the number
of axles._ 

_The TRUCK TRACTOR SEMI-TRAILER silhouette includes all truck tractor
combinations regardless of the number of axles._ 

_The SINGLE-UNIT TRUCK WITH ONE TRAILER includes all MAXI-CUBE and
TANDEM TRAILER combinations regardless of the number of axles._ 

So it is about the configuration of the vehicle and not about the number
of axles. 

As was mentioned by another poster, a ton here seems to be a "short
ton", i.e. 2000 pounds (907kg), which is not the normal imperial ton of
2240 pounds (1016kg) or the metric ton of 1000kg. Perhaps the unit
should be explicitly mentioned in the value (irrespective of which tag
is used), e.g. "25 st".
