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 Connecticut, the laws that apply to driving under the influence of alcohol or drugs (DUI) do not explicitly include bicycles. The state's DUI statutes typically apply to 'motor vehicles,' which does not encompass non-motorized bicycles. However, this does not mean that riding a bicycle while impaired is without consequence. Law enforcement officers may use other public safety laws to address situations where a cyclist is riding under the influence and posing a danger to themselves or others. For instance, a cyclist could potentially be charged with reckless endangerment or disorderly conduct. It's important to note that while there may not be a specific cycling under the influence (CUI) law in Connecticut, cyclists should always ride responsibly for their safety and the safety of others.
