At the highest levels of Missouri’s DWI sentencing framework, the law essentially removes judicial discretion in favor of long-term, mandatory prison sentences. These classifications—Chronic and Habitual—are reserved for those with four or more prior convictions.

Chronic Offender (4 Prior Convictions)

• Classification: Class C Felony.
• Maximum Penalty: 3 to 10 years in prison (DOC) and a fine of up to $10,000.
• Mandatory Minimum: You must serve at least 2 years in prison before you are even eligible for probation or parole.
• Probation Reality: At this level, probation is rarely granted by the court without the offender serving the full two-year mandatory minimum first.

Habitual Offender (5+ Prior Convictions)

• Classification: Class B Felony.
• Maximum Penalty: 5 to 15 years in prison.
• Mandatory Minimum: Similar to Chronic offenders, you must serve a minimum of 2 years in prison before becoming eligible for any form of probation or parole.
• Dangerous Felony Rule: If the offense involved a death, “Dangerous Felony” rules may apply, potentially requiring the offender to serve 85% of their total sentence before parole eligibility.

Common Thread: No More “Shortcuts”

For both Chronic and Habitual offenders, the standard options used in lower-level offenses are completely off the table:

• No Community Service Option: You cannot perform community service to avoid the mandatory prison time.
• No SIS: A Suspended Imposition of Sentence is prohibited by statute.
• Mandatory Prison – Department of Corrections (DOC).
