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 Massachusetts, there is no specific statute that addresses Cycling Under the Influence (CUI) in the same way that motor vehicle DUI (Driving Under the Influence) laws are structured. However, this does not mean that riding a bicycle under the influence of alcohol or drugs is without legal consequences. While cyclists may not be prosecuted under traditional DUI statutes, they can still be subject to public safety laws. For instance, law enforcement officers may take measures to protect an intoxicated cyclist and others on the road, which could include placing the cyclist in protective custody. Additionally, local ordinances may have specific regulations regarding cycling behavior, including the operation of bicycles while impaired. It is important for cyclists to be aware of and comply with all applicable local laws to ensure safety and avoid legal issues.
