Understanding Financial Penalties for DWI in Missouri

Getting charged with a Driving While Intoxicated (DWI) offense in Missouri triggers a series of consequences, and among the most immediate concerns for many individuals is the cost. DWI fines are one of the central components of these penalties, but they are just the beginning of the financial obligations that follow a conviction. While Missouri sets specific maximum fines for each offense level, the total out-of-pocket costs often go far beyond the court-imposed fine.

In Missouri, DWI offenses are criminal matters handled through the court system. Depending on the details of the case—such as whether it’s a first offense or a felony repeat offense—individuals can face hundreds to thousands of dollars in financial penalties. Court fines are often accompanied by administrative fees, mandatory program costs, and other required payments that quickly add up.

Understanding the full scope of fines and related expenses can help drivers better grasp the financial impact of a DWI charge. This overview explains how DWI fines are structured in Missouri, how they increase with each offense, and what additional costs may apply throughout the process. Whether you’re facing a first offense or a more serious charge, being informed about the monetary consequences is essential for preparing for what lies ahead.

DWI Fine Amounts by Offense Level

Missouri classifies DWI offenses by severity and number of prior convictions. Fines increase as the offense level rises, reflecting the state’s goal of discouraging repeat violations.

First Offense – Class B Misdemeanor

• Maximum Fine: $1,000
• Typical Range: $500 to $1,000, depending on circumstances and court discretion
• Additional Costs: Court fees, administrative surcharges, and program costs

A first DWI conviction in Missouri is usually classified as a Class B misdemeanor. While the maximum fine allowed by law is $1,000, many courts impose fines below that ceiling, especially if the offense did not involve aggravating factors like a high BAC or property damage. However, this base fine does not reflect the full financial picture.

Second Offense – Class A Misdemeanor

• Maximum Fine: $2,000
• Additional Costs: Higher program costs, longer ignition interlock requirements, and more supervision

A second DWI within five years escalates the case to a Class A misdemeanor, with fines up to $2,000. Courts may be less lenient with repeat offenders and are more likely to impose higher fines along with mandatory attendance in more intensive alcohol programs. Drivers may also face additional compliance costs tied to their probation or monitoring requirements.

Third Offense – Class D Felony

• Maximum Fine: $10,000
• Additional Costs: Felony court costs, extended monitoring, potential loss of vehicle

A third DWI offense is categorized as a Class D felony and carries a significant increase in the potential fine—up to $10,000. In felony cases, judges have broader authority to impose substantial financial penalties alongside long-term driving restrictions, extended ignition interlock requirements, and high-cost treatment programs. The cumulative financial impact can be extensive and long-lasting.

Mandatory Fees and Additional Financial Penalties

DWI fines in Missouri are only part of the cost. Every conviction brings along a list of mandatory fees and charges that vary by county and offense level. These may not be as visible as the main fine but are unavoidable components of the process.

Common Additional Financial Penalties Include:

• Court Costs: Typically range from $150 to $300
• Substance Abuse Traffic Offender Program (SATOP): $200–$500+ depending on track assignment
• Ignition Interlock Device (IID): $100–$200 installation, plus $70–$100 monthly
• License Reinstatement Fee: $45 to $100
• Probation Supervision Fees: Varies by jurisdiction, often $30–$60/month
• Victims’ Compensation Fund Contributions: May be automatically assessed with court costs
• Towing and Storage Fees: If your vehicle was impounded, costs can range from $150 to $500 or more

These costs are in addition to the actual fine imposed by the court and must be paid in order to satisfy the terms of probation or to regain full driving privileges. Ignoring or delaying payment of these amounts can lead to further license suspension, probation violations, or additional penalties.

Cost of Mandatory Programs: SATOP and More

Anyone convicted of a DWI in Missouri is required to complete an approved Substance Abuse Traffic Offender Program (SATOP). SATOP is administered by the Missouri Department of Mental Health and is a critical step in the reinstatement of driving privileges.

SATOP consists of several program “tracks,” each tailored to the severity and context of the offense:

• Offender Education Program (OEP): $200–$250
• Weekend Intervention Program (WIP): $400–$500
• Level IV Programs (CIP or SROP): Up to $1,000 for long-term interventions

The track assignment depends on the results of a mandatory assessment, which itself costs around $126. These programs must be completed in full for the driver to restore their license or fulfill sentencing requirements. If a person fails to complete the assigned track, they may face extended license suspension and be barred from progressing in their case.

SATOP fees are non-refundable and paid directly to the service providers, who operate under state guidelines. In some cases, additional treatment services may be recommended, increasing total program costs.

Ignition Interlock Devices and Their Financial Impact

For many DWI offenders in Missouri—especially repeat offenders or those with high BAC levels—the court or the Missouri Department of Revenue may require installation of an Ignition Interlock Device (IID) as a condition of continued or reinstated driving privileges.

Typical IID Costs Include:

• Installation Fee: $100 to $200
• Monthly Monitoring Fees: $70 to $100/month
• Removal Fee: May apply at the end of the restriction period

An IID is a breath-testing device connected to a vehicle’s ignition system. The driver must blow into the device to prove they are not under the influence before starting the car. The costs of installation, maintenance, and calibration are paid entirely by the offender. Failure to comply with IID requirements can result in re-suspension of driving privileges or even criminal charges.

Depending on the length of required use—often 6 to 12 months or more—the cost of an IID can easily exceed $1,000 for a single DWI case.

License Suspension and Reinstatement Costs

Missouri’s administrative penalties for DWI also affect your wallet. If your license is suspended or revoked, there are specific steps—and costs—required for reinstatement.

Key Reinstatement-Related Costs Include:

• Reinstatement Fee: $45 (after suspension)
• SR-22 Insurance Filing: Cost varies, but adds $20–$50/month to premium
• Proof of SATOP Completion: Required before reinstatement
• Ignition Interlock Verification: Required for drivers with IID conditions

In many cases, drivers must maintain SR-22 insurance for up to 3 years following a DWI-related suspension. This specialized form of high-risk auto insurance is significantly more expensive than standard coverage and adds hundreds or even thousands to the overall financial impact of a DWI.

Long-Term Costs: Insurance and Employment Impact

DWI fines and court-related expenses represent only part of the cost. For many drivers, the most significant financial consequences are long-term and indirect—especially in the form of auto insurance and employment limitations.

Auto Insurance Increases:

• After a DWI, drivers are typically reclassified as high-risk
• Insurance rates can double or triple
• Some insurers may cancel coverage, requiring the driver to seek a more expensive policy
• SR-22 requirements further increase premiums

Over the course of three years, the additional cost of insurance following a DWI can range from $3,000 to $10,000 or more, depending on age, location, and prior driving history.

Employment-Related Costs:

• Loss of job opportunities due to criminal record
• Difficulty obtaining professional licenses
• Travel restrictions for job roles requiring clean driving records
• Time off work to attend court, programs, or DMV hearings

Some industries, particularly those involving transportation, education, security, or government, may disqualify applicants with DWI convictions or require costly legal compliance before reinstating employment.

Cost Differences by County and Case Type

Missouri’s DWI fines and penalties are subject to statewide maximums, but many costs vary by county or even by individual court. Some jurisdictions impose higher court costs or stricter payment deadlines. Others may offer diversion programs or deferred prosecution that reduce long-term penalties—but only after higher upfront fees and intensive monitoring.

Additionally, aggravating factors—such as:

• BAC of 0.15% or higher
• Minor passengers in the vehicle
• Accidents involving injury or damage

…can increase both fines and associated fees, even on a first offense. These enhancements don’t change the basic classification of the offense but do raise the financial and procedural consequences.
