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 Maine, the laws that apply to driving under the influence of alcohol or drugs (DUI) do not explicitly include bicycles. Maine's DUI laws pertain to 'motor vehicles,' which does not encompass non-motorized bicycles. However, cyclists in Maine are still subject to public intoxication laws and can be cited or arrested for endangering themselves or others while riding a bicycle under the influence. Additionally, local ordinances may have specific regulations regarding cycling under the influence. It is important for cyclists to be aware of and comply with all applicable local laws. Despite the lack of a specific cycling under the influence (CUI) law in Maine, it is advisable to avoid cycling while impaired as it can lead to dangerous situations and potential legal consequences.
