Stacking in Wisconsin
Prior to Governor Walker's repeal of Truth in Auto, in cases involving serious or catastrophic injuries Wisconsinites were allowed to add up the coverages for every car they insured with the same insurance company. Unlike the scare tactics used by the Wisconsin insurance companies, stacking was not a common everyday occurrence. It was only in those rare cases where people were catastrophically injured and deservedly needed additional benefits that stacking occurred.
