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 North Dakota, the laws that apply to driving under the influence (DUI) of alcohol or drugs primarily target motor vehicles and do not explicitly include bicycles. Under North Dakota Century Code 39-08-01, a DUI is defined in the context of operating a 'motor vehicle.' Since bicycles are not motor vehicles, the state's DUI laws do not directly apply to cycling under the influence. However, cyclists could potentially be charged under public intoxication or other relevant laws if their behavior is deemed to be a danger to themselves or others. It is important for cyclists to be aware that even without specific cycling under the influence laws, riding a bicycle while impaired can still lead to legal consequences and is dangerous to both the cyclist and others on the road.
