In Missouri, the crime typically referred to as Drunk Driving is knows as Driving While Intoxicated or DWI. in other states, it is knows as Driving Under the Influence or DUI. Specifically speaking, there is no offense of DUI in Missouri. All alcohol or drug related driving offenses where impairment is alledged are DWIs or Driving While Intoxicated. A related offense Driving with excessive Blood Alcohol Content or BAC is also recognized in Missouri, but seldom used save in very specific fact circumstances or as a part of a plea bargain.
Statutory Authority and Definition
The criminal offense of Driving While Intoxicated is defined by Missouri Law in RSMo. 577.010 which states:
"A person commits the crime of "driving while intoxicated" if he operates a motor vehicle while in an intoxicated or drugged condition.
While on the surface it seems straight forward enough, certain questions arise as to the specific meaning of the words used to define the offense. Such as:
- What does it mean to "operate" a motor vehicle? Open the door? Roll down the windows? Does the motor vehicle need to move? Does the engine need to be running?
- What is a "motor vehicle"? Does a lawn mower count? Does it need to be a gasoline engine? What about a moped in bicycle mode?
- What is intoxicated?
RSMo. 511.001 is a definition section that helps clarify some, but not all of these questiions. It says in part:
- As used in this chapter, the term "drive", "driving", "operates" or "operating" means physically driving or operating a motor vehicle.
- As used in this chapter, a person is in an "intoxicated condition" when he is under the influence of alcohol, a controlled substance, or drug, or any combination thereof.
Not real helpful, is it?
That's where the courts step in and try to help further define these issues, which will be discussed in other posts.
