Some states have laws against riding a bicycle on a street or highway while under the influence of drugs or alcohol (cycling under the influence, or CUI). Other states apply traditional DUI/DWI laws to cycling while under the influence of drugs or alcohol. And some states don't have a specific CUI law, and don't apply traditional DUI/DWI laws to riding a non-motorized vehicle, such as a bicycle.
In Wisconsin, the laws that apply to driving under the influence of alcohol or other drugs (DUI) do not extend to bicyclists. Wisconsin's DUI laws are specific to motor vehicles, and bicycles are not defined as motor vehicles under these statutes. Therefore, a person riding a bicycle under the influence of alcohol or drugs would not be charged under the same statutes as a motor vehicle driver would be for DUI. However, it is important to note that while there may not be a specific cycling under the influence (CUI) law in Wisconsin, bicyclists can still be cited for other offenses or be subject to civil liability if their actions result in property damage, injury, or death. Additionally, local ordinances may have regulations regarding the operation of bicycles that could apply to riding while impaired.
