Legal Definition of Dui in Missouri
Missouri’s DUI laws, often referred to as Driving While Intoxicated (DWI) laws are detailed in the Missouri Revised Statutes § 577.010 and § 577.012. Under these statutes, a person commits the offense of DWI if they operate a motor vehicle while under the influence of alcohol, drugs, or a combination of both. The legal blood alcohol concentration (BAC) limit is 0.08% for drivers aged 21 and over, 0.04% for commercial drivers, and any detectable amount of alcohol for drivers under 21.
Key Elements of a Dui Case
To secure a DUI conviction in Missouri, the prosecution must prove several elements beyond a reasonable doubt:
- Operation of a Vehicle: The individual must have been driving or in actual physical control of a motor vehicle.
- Impairment: The driver must have been impaired by alcohol, drugs, or both, which is typically demonstrated through chemical tests (blood, breath, urine) or observed impairment (field sobriety tests).
Types of Evidence Used in Dui Cases
The prosecution can use various types of evidence to establish impairment:
- Chemical Test Results: Blood, breath, or urine tests showing a BAC of 0.08% or Chemical tests must be conducted properly to be admissible in court.
- Field Sobriety Tests: Observations from standardized tests such as the walk-and-turn, one-leg stand, and horizontal gaze nystagmus. These tests assess physical and cognitive impairment.
- Witness Testimony: Statements from officers or other witnesses about the driver’s behavior, speech, and appearance.
- Video Evidence: Dashcam or bodycam footage showing the driver’s conduct during the traffic stop.

- Inaccurate Test Results: Challenging the validity and accuracy of the chemical tests.
- Field Sobriety Test Issues: Questioning the administration and interpretation of field sobriety tests.
- Medical Conditions: Demonstrating that a medical condition affected the driver’s behavior or test results.
Impact on Criminal Record
A DUI conviction can have long-lasting effects on a person’s criminal record. It may affect employment opportunities, result in higher insurance premiums, and lead to other social and financial consequences. Expungement of a DUI conviction is possible under certain conditions but is generally a complicated process that requires legal assistance.
Legal Procedures in a DUI Case
When a person is arrested for DUI, the legal process typically involves several stages:
- Arraignment: The defendant appears in court to hear the charges and enter a plea.
- Pre-Trial Motions: Both parties can file motions to suppress evidence or dismiss the case.
- Trial: If the case goes to trial, the prosecution presents its evidence, and the defense can cross-examine witnesses and present its own evidence.
- Sentencing: If convicted, the court imposes penalties based on the severity of the offense and the defendant’s prior record.
Treatment Programs and Probation
Missouri offers various treatment programs for DUI offenders, ranging from short-term education courses to long-term residential treatment programs. Participation in these programs is often a condition of probation.Probation typically lasts for two years and requires compliance with court-ordered conditions such as sobriety monitoring and regular check-ins with a probation officer.
Community Service and Restitution
In addition to jail time and fines, DUI offenders may be required to perform community service or pay restitution to victims if the DUI resulted in injury or property damage. Community service hours vary depending on the severity of the offense and the court’s discretion.
Technology and Monitoring
Modern technology plays a significant role in monitoring DUI offenders. Courts may require the installation of ignition interlock devices (IIDs) in offenders’ vehicles.
These devices prevent the vehicle from starting if the driver has been drinking. Continuous alcohol monitoring devices and random drug testing are also common conditions of probation.
Implied Consent Law
Missouri’s implied consent law requires drivers to submit to chemical testing if they are lawfully arrested for DUI. Refusal to take the test results in automatic administrative penalties, including a one-year license revocation and mandatory completion of a Substance Abuse Traffic Offender Program (SATOP) before license reinstatement.
Field Sobriety Tests and Chemical Testing
Field sobriety tests are standardized tests used by law enforcement to assess a driver’s level of impairment. These tests include the walk-and-turn, one-leg stand, and horizontal gaze nystagmus tests. Chemical tests, such as breathalyzers, blood tests, and urine tests, are used to measure the driver’s BAC. Proper administration and calibration of these tests are crucial for their validity in court.
Legal Rights and Responsibilities
Drivers have specific rights and responsibilities when stopped for suspected DUI:
- Right to an Attorney: Drivers have the right to contact an attorney before submitting to chemical tests.
- Right to a Second Test: Drivers can request a second test from a physician, technician, chemist, or registered nurse if they question the accuracy of the initial test.
