Missouri DUI Laws Explained: Penalties, License Suspension & First Offense
Facing a DUI charge in Missouri can be overwhelming. Between court appearances, license issues, and potential fines, it’s important to understand what the law actually says and what steps you may need to take next.
What Counts as a DUI in Missouri
In Missouri, driving under the influence is legally referred to as Driving While Intoxicated (DWI). You can be charged if your blood alcohol concentration (BAC) is 0.08% or higher, or if an officer determines that drugs or alcohol have impaired your ability to drive safely—even if your BAC is below that threshold. For commercial drivers, the limit is 0.04%, and for drivers under 21, it’s 0.02%.
Penalties for a First Offense
A first-time DWI in Missouri is typically classified as a Class B misdemeanor. The penalties may include:
- Jail Time
- Fines
- License suspension
- Substance Abuse Traffic Offender Program (SATOP)
In some cases, an ignition interlock device may be required. While these are the standard penalties, individual outcomes can vary depending on the circumstances of the arrest, prior history, and the strength of available evidence.
License Suspension and Administrative Hearings
When you’re arrested for DWI, the Missouri Department of Revenue can take administrative action against your driver’s license even before a criminal conviction occurs. You typically have 15 days from the date of notice to request a hearing to contest the suspension. Failing to act within that window can lead to an automatic loss of driving privileges.
Why Legal Guidance Matters
DWI cases are complex and time-sensitive. From field sobriety testing to chemical evidence, small details can have a major impact on the outcome. Consulting an attorney who understands Missouri’s DWI process can help you navigate your options, protect your rights, and work toward the best possible resolution.
