Missouri First Offense DWI

Missouri First Offense DWI Laws Explained in Easy to Understand Simple Terms

In Missouri, a first offense DWI (Driving While Intoxicated) can be a critical legal and personal challenge for those charged. Missouri law enforces strict penalties to deter driving under the influence of alcohol or drugs, reflecting a strong commitment to road safety. A first offense DWI is generally classified as a Class B misdemeanor, which can carry penalties including fines, potential jail time, and a suspension of driving privileges. The state’s Blood Alcohol Concentration (BAC) limit is set at 0.08% for drivers 21 and over, and lower limits apply to commercial drivers and those under 21, emphasizing the state’s rigorous standards.

Key Aspects of a First Offense DWI in Missouri

Dealing with a first DWI offense in Missouri involves understanding several key aspects that can impact the outcome and consequences for the individual involved:

  1. Legal Limits and Penalties: Missouri enforces a strict blood alcohol concentration (BAC) limit of 0.08% for drivers aged 21 and over. For those under 21, a lower limit applies, reflecting Missouri’s zero-tolerance policy towards underage drinking and driving. A first offense typically results in a Class B misdemeanor charge, including penalties such as fines up to $500, up to six months in jail, and a 90-day suspension of driving privileges. These penalties underscore the state’s commitment to deterring impaired driving.
  2. Administrative vs. Criminal Proceedings: In Missouri, a DWI case involves administrative and criminal proceedings. The administrative process deals primarily with suspending the driver’s license, which can be immediately affected upon arrest if the driver fails or refuses a BAC test. This suspension can be contested at an administrative hearing. Separately, the criminal aspect addresses the charges and penalties, such as fines and jail time. Navigating both proceedings requires timely and informed actions, often necessitating legal assistance.
  3. Rehabilitation and Education: Missouri places a strong emphasis on rehabilitation following a DWI conviction. Offenders may be required to participate in alcohol education programs, undergo substance abuse treatment, or attend victim impact panels as part of their sentence. These requirements aim to educate offenders about the dangers of impaired driving and reduce the likelihood of future offenses, contributing to broader public safety efforts.

Understanding these aspects can help individuals better manage the situation if they face a DWI charge in Missouri. Legal guidance and compliance with state laws can mitigate the impact of such charges.

First Offense DUI Penalties

Here’s a detailed breakdown of the penalties for a first offense DWI in Missouri:

  1. Legal Classification: A first offense DWI is typically classified as a Class B misdemeanor. If there are aggravating factors, such as having a passenger under 17 in the vehicle, it can escalate to a Class A misdemeanor or higher in cases involving injury or death.
  2. Jail Time: For a standard first DWI, there is a potential for up to six months in jail. However, jail time can be significantly higher if the offense includes aggravating circumstances.
  3. Fines: The fines for a first offense DWI can be up to $1,000. If the DWI results in injuries or other aggravating factors, the fines can be much higher, especially in felony cases.
  4. Driver’s License Suspension: The standard suspension for a first offense is 90 days. However, after 30 days, the offender might be eligible for a restricted driving privilege, which often requires the installation of an ignition interlock device.
  5. Ignition Interlock Device: An ignition interlock device may be required for reinstating driving privileges under a restricted license. This device must be used for the duration specified by the court or the Department of Revenue.
  6. Alcohol Education and Treatment: Missouri requires DWI offenders to participate in the Substance Awareness Traffic Offender Program (SATOP). This program includes an assessment and may require completion of education or treatment programs based on the level of the offender’s alcohol-related issues.
  7. Additional Costs: Beyond fines and legal fees, there are costs associated with the SATOP program, ignition interlock devices, increased insurance premiums, and possibly towing and storage fees if the vehicle was impounded.
  8. Criminal Record: A conviction will generally result in a criminal record, but Missouri offers a suspended imposition of sentence for some first-time offenders, which can prevent a permanent conviction record if the individual meets certain conditions.

These penalties reflect Missouri’s stringent approach to handling DWI offenses, emphasizing both punishment and rehabilitation to deter impaired driving. For more specific scenarios or further information, consulting a legal expert or referring to local legal resources would be advisable.

  1. License Suspension: An underage driver’s first offense results in a 30-day license suspension. Subsequent offenses can lead to longer suspensions, with a second offense resulting in a 90-day suspension and a third offense leading to a one-year suspension.

CDL First Offense DUI Penalties

For commercial drivers in Missouri, the consequences of a first offense DWI can be quite severe, especially considering their need to maintain a clean driving record for employment. Here are the key penalties for a CDL holder convicted of a first-time DWI:

  1. CDL Disqualification: A first-time DWI results in an automatic disqualification of the commercial driver’s license (CDL) for one year. This applies regardless of whether the offense occurred while operating a commercial vehicle or a personal vehicle​ (DWI Attorney Matt Fry)​​ (Missouri DWI & Criminal Law Center)​​ (DWI Springfield)​.
  2. Lower BAC Threshold: For CDL holders, the legal blood alcohol content (BAC) limit is 0.04%, which is half the standard limit for non-commercial drivers. Being caught with a BAC at or above this limit while operating any vehicle can trigger the disqualification​ (DWI Attorney Matt Fry)​​ (Missouri DWI & Criminal Law Center)​.
  3. Additional Consequences: Alongside the CDL disqualification, the driver may also face penalties such as fines, potential jail time, and increased insurance premiums. The exact penalties can vary, but they typically include a fine and the possibility of jail time up to six months for a first offense​ (DWI Springfield)​.

These penalties underline the stringent standards that CDL holders are held to in Missouri, reflecting the high level of responsibility associated with commercial driving. If a CDL holder is convicted of a DWI, this not only affects their legal standing but also significantly impacts their professional life and ability to work in commercial driving roles.

Ignition Interlock Requirements First Offense DUI

In Missouri, the ignition interlock device (IID) requirement for first-time DWI offenders varies depending on certain conditions. If you are a first-time offender, you may be required to install an IID as part of obtaining a Restricted Driving Privilege (RDP). This RDP allows you to drive under specific conditions, like going to work or school, during the period of your license suspension. The installation of an IID might be required for the entire duration of the RDP, which typically lasts for 90 days​ (Intoxalock)​.

Moreover, the use of an IID can also be mandated if you refuse to submit to a chemical breath test when arrested, which leads to a one-year driver’s license revocation. In such cases, installing an IID becomes a prerequisite for regaining driving privileges after the suspension period​ (Legal Beagle)​.

Implied Consent Law

In Missouri, the implied consent law means that if you’re driving, you’ve automatically agreed to submit to a chemical test to determine your blood alcohol concentration (BAC) if you’re arrested for driving while intoxicated (DWI). Refusing this test can lead to significant penalties, including a one-year license revocation. This revocation is separate from any criminal consequences you might face if convicted of DWI. Interestingly, even if a DWI charge is dismissed, these penalties for refusal can still apply​ (dui.drivinglaws.org)​.

The law allows for some choice in the type of test—breath, blood, or urine—with the breath test being the most common due to its immediate results. However, each type of test has its advantages and considerations, and it’s often recommended to consult with a DUI lawyer to understand the best option based on your specific situation​ (FEDERAL LAWYERS [2024])​.

DUI Class Requirements


In Missouri, if you are charged with a first-offense DWI, you are typically required to participate in the Substance Abuse Traffic Offenders Program (SATOP). For most first-time offenders, this involves attending a 10-hour Level-One Offender Education Program. The program is designed for those deemed “low risk” and consists of four sections, each lasting 2.5 hours. These sessions may be conducted separately or combined into two longer sessions. The costs associated with this program include an initial screening fee and the fee for the class itself, which generally totals around $245​ (KansasCityDWIattorneyMJG)​​ (KansasCityDWIattorneyMJG)​.

Driver License Hearing

In Missouri, if you’re facing a first-offense DWI, the driver’s license hearing is a critical part of the administrative process. At the hearing, there is no judge or jury; instead, an officer from the Department of Revenue oversees the proceedings. The primary witness at this hearing is typically the arresting officer. Your attorney can question the arresting officer about the details of the arrest, including the validity and accuracy of any tests conducted, like breath or chemical tests. This is an opportunity to challenge the evidence against you.

If the Department of Revenue officer finds the arguments against suspension convincing, your license may not be suspended. However, if the officer decides against you, your license will be suspended, and this decision is communicated within 10 days of the hearing​ (Higher Level Legal)​.
