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 Kansas, the laws that apply to driving under the influence (DUI) of alcohol or drugs do not explicitly include bicycles. Kansas DUI statutes typically apply to 'vehicles,' and under Kansas law, a vehicle is defined as a device that is capable of moving itself, or being moved, on wheels. However, bicycles are not considered 'vehicles' in the context of DUI laws. Therefore, Kansas does not have a specific cycling under the influence (CUI) law, and traditional DUI/DWI laws do not apply to riding a non-motorized vehicle such as a bicycle. Nonetheless, cyclists may still be subject to other laws and local ordinances that address public safety and the operation of bicycles, and it is always advisable to ride responsibly.
