In regards to the number of uninsured motorists in 2012, the state of Wisconsin ranked 25 in the country with 11.7 of its motorists being uninsured, according to a report by the Insurance Information Institute. The state of Massachusetts carried the fewest amount of uninsured motorists, and Oklahoma carried the highest amount at 26 percent.
It appears that the numbers have steadily been decreasing over the last 20 years, however, with 15.6 percent of motorists being uninsured in 1992 as compared with 12.6 percent, or roughly one in eight drivers, in 2012. This may be because motorists who reside in the 20 designated states and the District of Columbia are required by law to carry underinsured or uninsured coverage on their car insurance policies. Moreover, other states, such as Texas and Nevada, are cracking down on uninsured motorists by identifying them through online car insurance checking systems.
