DUI / DWI

cycling under influence (CUI)

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 Montana, the laws that apply to driving under the influence of alcohol or drugs (DUI) do not directly apply to cyclists. Montana's DUI laws are specific to 'vehicles,' which under Montana Code Annotated (MCA) 61-1-101, are defined as devices in, upon, or by which a person or property is or may be transported or drawn upon a highway, excepting devices moved by human power. Therefore, bicycles, being human-powered, are not included under this definition of vehicles for the purposes of DUI laws. However, cyclists in Montana are still subject to public intoxication laws and can be cited or arrested for endangering themselves or others while cycling under the influence. It's important to note that while there may not be a specific Cycling Under the Influence (CUI) statute in Montana, law enforcement officers can take measures to prevent accidents if they determine a cyclist is impaired.
