Statutory framework and criminal grading in Missouri
Under RSMo § 577.010, operating a motor vehicle with a blood alcohol concentration of 0.08 or higher, or under the intoxicating influence of controlled substances, constitutes an impaired driving offense. 30-day hard suspension followed by 60 days restricted driving with interlock.
As a Class B Misdemeanor, a first conviction involves mandatory sentencing guidelines established by state statute. These include minimum statutory fines, community service requirements, court-ordered alcohol screening assessments, and mandatory attendance at state-certified driver safety education seminars.
