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 Carolina, traditional DUI (Driving Under the Influence) laws apply to the operation of motor vehicles and do not explicitly include bicycles. North Carolina General Statutes ยง 20-138.1 outlines the offense of impaired driving but refers to drivers of vehicles, and a vehicle is defined under North Carolina law as something that is self-propelled, which would not typically include a bicycle. However, while there may not be a specific Cycling Under the Influence (CUI) law, cyclists could potentially be charged under public intoxication or similar statutes if their behavior is deemed to be a danger to themselves or others. It is important for cyclists to be aware that even without a specific CUI law, riding a bicycle while impaired can still lead to legal consequences and is dangerous to both the cyclist and others on the road.
