Important things to know with respect to permits involving 98,000
pounds on 6-axles:
The Wisconsin Department of Transportation (WisDOT) is the
only agency that may issue a “Raw Forest Products Permit” (RS
Permit) per Wis Statute 348.27(9m)(a)4.

RS Permits are not valid on Interstate highways.
RS permits do not authorize exceeding posted weight limits,
except for seasonal limits on marked State or US routes in
connection with thawing of frozen roads.
During the spring thaw period established by WisDOT, the RS
Permit allows transport on any highway that is marked State or US
route including those posted to limit weights seasonally in
connection with thawing of frozen roads. RS permits also remain
valid during spring thaw on all other public roads but are subject
to all posted weight limits, including seasonal limits.
