Wis. Admin. Code § Trans 254.09
(3) An oversize vehicle used for transporting loads under a permit shall be reduced to legal size whenever possible when being operated without load.
Note: Legal sizes are set forth in ch. 348 and s. 349.16, Stats.
(8) Loads consisting of more than one article, one or more of which are oversize, may be transported under a permit only if:
(b) The other articles transported do not cause the vehicle and load to be oversize in any manner differently from the largest single article.
Note: For example, if a storage tank which is overwidth and overheight (but not overlength) is the single largest article transported, then a toolbox which is not wider, and is not higher, and does not make the vehicle and load overlength or overweight may also be transported.
However, a beam placed crosswise which makes the overall width wider than the storage tank may not be transported as an additional article. Similarly, a beam placed lengthwise which makes the vehicle and load overlength may not be transported as an additional article.
Finally, if the vehicle and load were overweight, then no additional article may be transported.
