About DWI in Missouri
The Crime Driving While Intoxicated is the only crime for which an individual can be convicted solely on the opinion of law enforcement.
In order to convict someone over the age of 21 of DWI, the state must prove beyond a reasonable doubt that the person was (1) operating or in physical control of (2) a motor vehicle on (3) any public road, highway, alley, parking lot, or any other premises generally frequented by the public while (4) under the influence of alcohol or drugs, or with a blood alcohol content of .08% or higher.
A person over the age of 21 may be convicted of DWI if their blood alcohol content was .08% or higher at the time of the offense, even if their ability to drive was not impaired. A person may also be convicted of DWI for operating a vehicle while under the influence of a narcotic, even if it was prescribed by a physician.
If you are under 21 years of age there is zero tolerance and you can be arrested and convicted of DWI for any blood alcohol content above .02%.
