An Aggravated DUI, DWI, OUI, or OWI (driving under the influence, driving while intoxicated, operating under the influence, or operating while intoxicated) is the criminal offense of DUI/DWI/OUI/OWI—with additional aggravating circumstances that enhance or make the offense a greater crime—resulting in greater potential punishments.

Aggravating circumstances that may result in an Aggravated DUI/DWI/OUI/OWI charge include (1) a blood alcohol concentration (BAC) that is significantly higher than the legal limit; (2) an accident in which a person is injured or killed, or in which there is property damage; (3) a minor child in the car being transported by the alleged intoxicated driver; (4) driving 20 mph or more over the speed limit; (5) the driver is under the legal age for drinking (generally 21); (6) refusing to submit to a chemical test of blood, breath, or urine; and (7) prior convictions for DUI/DWI/OUI/OWI.

Laws regarding the definitions and names of alcohol and drug-related driving offenses—including the consideration and definitions of aggravating circumstances—vary from state to state and are usually located in a state’s statutes—often in the penal code or criminal code.

In Wyoming (WY), an Aggravated DUI (Driving Under the Influence) is a more serious offense than a standard DUI, due to certain aggravating circumstances. Wyoming law considers a number of factors that can elevate a DUI to an Aggravated DUI, including having a BAC (Blood Alcohol Concentration) significantly above the legal limit of 0.08%, causing an accident resulting in injury, death, or property damage, having a minor in the vehicle, excessive speeding (such as 20 mph over the speed limit), being under the legal drinking age of 21, refusing to submit to a chemical test, and having prior DUI convictions. These factors can lead to enhanced penalties such as longer jail time, higher fines, and extended driver's license suspension periods. The specific statutes detailing DUI and Aggravated DUI laws in Wyoming can be found in Title 31 (Motor Vehicles) of the Wyoming Statutes. It is important for individuals facing such charges to consult with an attorney who is knowledgeable in Wyoming DUI laws to understand the potential consequences and legal options available.
