As has been discussed in a previous post, driving under the influence, or DUI is not necessarily what we might call “drunk driving.” In fact, if you take a look at the actual Mississippi DUI statute, you will find that the term “drunk” is nowhere to be found.

It is unlawful for a person to drive or otherwise operate a vehicle within this state if the person:

  1. Is under the influence of intoxicating liquor;
  2. Is under the influence of any other substance that has impaired the person’s ability to operate a motor vehicle;
  3. Is under the influence of any drug or controlled substance, the possession of which is unlawful under the Mississippi Controlled Substances Law; or
  4. Has an alcohol concentration in the person’s blood, based upon grams of alcohol per one hundred (100) milliliters of blood, or grams of alcohol per two hundred ten (210) liters of breath, as shown by a chemical analysis of the person’s breath, blood or urine administered as authorized by this chapter, of
    • Eight one-hundredths percent (.08%) or more for a person who is above the legal age to purchase alcoholic beverages under state law;
    • Two one-hundredths percent (.02%) or more for a person who is below the legal age to purchase alcoholic beverages under state law; or
    • Four one-hundredths percent (.04%) or more for a person operating a commercial motor vehicle.
