St. Louis Multiple DWI Lawyer
Defending Clients Facing Repeat DWI Charges in St. Louis, MO
While a first-time drunk driving charge in Missouri is serious, facing a repeat DWI triggers an aggressive response from prosecutors and judges. Missouri's repeat offender statutes mandate harsh escalating penalties—including mandatory jail time, multi-year or permanent driver's license denials, mandatory alcohol monitoring, and elevated felony charges.
At The Hammer Law Firm, LLC, we bring over 60 years of combined criminal law experience to your defense. As former prosecutors, attorneys Mark Hammer and Matt Wayman know how the state builds repeat DWI cases and where prosecutors are vulnerable. We scrutinize prior convictions, challenge the legality of past pleas, and fight the current evidence to protect your future.
Call (314) 334-3807 or contact us online today to schedule a free consultation with our St. Louis multiple DWI lawyer who will fight for your rights and help you move forward.
Second DWI
A second DWI offense in Missouri is classified as a Class A misdemeanor. While first-time offenders may be eligible for lighter penalties or diversion programs, repeat offenders often face harsher consequences due to the assumption of a pattern of dangerous behavior.
Penalties for a second DWI include:
- Up to one year in jail
- A fine of up to $2,000
- Minimum jail time of 10 days, which may not be suspended
- Five-year license revocation (if the prior offense was within five years)
- Installation of an ignition interlock device (IID)
- Mandatory substance abuse treatment or SATOP
- Community service and possible probation terms
Third DWI
A third DWI conviction in Missouri is classified as a Class D felony and earns you the title of a "persistent offender." At this stage, the penalties become even more severe, including extended incarceration and long-term effects on your civil rights and driving privileges.
Here are the penalties for a third DWI:
- Up to 4 years in prison
- Mandatory minimum of 30 days in jail or 480 hours of community service
- Up to $10,000 in fines
- 10-year license denial
- Mandatory alcohol or drug treatment
- Felony record, which can impact employment, housing, and firearm rights
Fourth or Subsequent DWI
A fourth or subsequent DWI is classified as a Class C, B, or A felony, depending on the number of prior convictions. A person with four or more prior DWIs can be deemed an "aggravated, chronic, or habitual offender" under Missouri law.
The following are penalties for fourth or subsequent DWI:
- Class C Felony: Up to 7 years in prison
- Class B Felony: 5–15 years in prison
- Class A Felony (habitual offender): 10–30 years or life imprisonment
- Lifetime license revocation
- No eligibility for expungement
- Extended supervision, treatment, and court monitoring
- Long-term installation of IID, if ever eligible to regain license
Why Repeat DWI Charges Are So Much More Serious in Missouri
A first DWI is often treated as a mistake. A second, third, or subsequent DWI is treated as a pattern — and Missouri prosecutors and judges respond accordingly. What many people don't realize is how the state counts prior offenses, and that misunderstanding can lead to serious surprises.
Two features of Missouri law make repeat DWIs especially dangerous:
- A lifetime lookback. Unlike some states that only count prior DWIs from the last five or ten years, Missouri generally counts prior intoxication-related offenses for your entire lifetime when deciding how to charge a new one. A DWI from decades ago can still elevate today's charge.
- Offender classifications, not simple offense numbers. Your exposure is defined by categories set out in state law — prior, persistent, aggravated, and chronic offender — each of which raises the offense level and unlocks harsher mandatory penalties.
Because of these rules, the difference between a misdemeanor and a felony can come down to how prior offenses are proven and classified. That is precisely the kind of issue an experienced DWI attorney can challenge.
