Neither Michigan or your home state of Wisconsin are members of the interstate reciprocal agreement known as the Drivers License Compact (DLC) however both states do share information with other states regarding convictions of moving violations.

According to the Wisconsin Department of Transportation (DOT), they do receive in information on convictions for traffic violations from WI licensed drivers from out of state courts. The WI DOT notes though that no points are assessed for convictions of traffic offenses from other states however the conviction is entered on your Wisconsin driver record.

Since the conviction of the MI speeding ticket is likely to be placed on your WI driving record your insurance company could see it the next time they pull your MVR and depending upon their rating system it could affect your rates. If you are only worried about points on your Wisconsin driving record though then you should be happy to know that no demerit points will be assessed.
