2015 - 2016 LEGISLATURE
February 18, 2016 - Introduced by Representatives Tranel, Tittl, Murphy, Novak
and Kulp. Referred to Committee on Transportation.
AB931,1,2 1An Act relating to: modifying administrative rules related to tinting of motor
2vehicle windows.
Analysis by the Legislative Reference Bureau
This bill changes the motor vehicle window tinting limitations contained in the
administrative code, allowing more opaque vent, side, and rear windows than under
current law.
Under current law, the Department of Transportation (DOT) is responsible for
enforcing motor vehicle equipment restrictions and may promulgate rules relating
to vehicle equipment standards. DOT rules include provisions detailing the extent
to which motor vehicle windows may be tinted. Among these rules, tinting of the
vent, side, and rear windows is permitted by the application of tinting film to the
inside of the glass provided that the combination of the glass and tinting film permits
passage through the windows of at least 35 percent of the visible light striking the
windows. This bill lowers the percentage of visible light that must be able to pass
through the glass and tinting film to 17 percent.
The people of the state of Wisconsin, represented in senate and assembly, do
enact as follows:
