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 Utah, the DUI (Driving Under the Influence) laws primarily target motor vehicle operators. However, Utah Code Section 41-6a-502 stipulates that a person may not operate or be in actual physical control of a vehicle if they are under the influence of alcohol or drugs to a degree that renders them incapable of safely operating the vehicle. While this law is generally applied to motor vehicles, it does not explicitly exclude bicycles. Therefore, in practice, a person cycling under the influence could potentially be charged under these DUI laws. It is important to note that local ordinances may also have specific provisions regarding cycling under the influence. As such, while Utah does not have a specific CUI statute, traditional DUI laws could be applied to cyclists, and it is advisable to avoid cycling while under the influence of drugs or alcohol to ensure safety and compliance with the law.
