DWI is a crime when operating a motor vehicle in a public place while intoxicated. Intoxication is not the same as drunk. The law defines intoxication as the loss of the normal use of your physical or mental faculties, or having alcohol concentration of 0.08 or greater in your breath, blood or urine. A person can be intoxicated from substances other than alcohol such as a controlled substance, drug, dangerous drug or a combination of two or more those substances into the body.
