Driving Under the Influence (DUI)

A person driving a car

You probably know that you can be arrested for driving a vehicle while under the influence of alcohol.  But there is more!  You can also be charged with DUI if you are operating a boat or an aircraft while under the influence of an inhalant (“huffing”) or controlled substance (roughly, any illegal drug or a legal drug taken without a prescription).  Furthermore, even if you do not feel impaired, you can be guilty of this crime if your blood alcohol measures more than .08 percent (80 milligrams or more of alcohol per 100 milliliters of blood, or .08 grams or more of alcohol per 210 liters of breath).  You should also know that you are considered to be “operating a vehicle” if you are in control of the vehicle, even if you are not driving it.  For example, you could be convicted of this crime if you are sitting in the driver’s seat with the keys between the seats.  You can read more about DUI and other alcohol-related crimes in Section 2 of this Guide.
