Second-Offense DWI in Missouri

A second DWI offense in Missouri — meaning you have one prior alcohol-related enforcement contact — is classified as a Class A misdemeanor under RSMo §577.010. While still a misdemeanor, the penalties and consequences escalate significantly compared to a first offense. Prosecutors treat second offenses as a pattern rather than an isolated mistake, and judges are far less inclined toward leniency.

Penalties

Criminal Penalties

  • Class A Misdemeanor: Up to 1 year in jail and up to $2,000 fine.
  • Mandatory jail or community service: Missouri law requires a minimum of 10 days in jail or 30 days of community service for a second DWI conviction. This is mandatory — the judge cannot waive it.
  • Probation with strict conditions: Typically includes substance abuse treatment, regular testing, and compliance monitoring.

License Consequences

  • 5-year license revocation: A second alcohol-related offense results in a 5-year revocation of your driving privileges — dramatically longer than the 90-day suspension for a first offense.
  • Ignition interlock device (IID): You may be required to install an IID on your vehicle as a condition of obtaining a restricted driving privilege during the revocation period.
  • Limited driving privilege: After a waiting period, you may be eligible for a restricted license — but the requirements are more stringent than for first offenders.

What Counts as a "Prior"?

Missouri uses the concept of "prior alcohol-related enforcement contacts" to determine whether a DWI is a first, second, or subsequent offense. A prior includes any previous DWI conviction, guilty plea, suspended imposition of sentence (SIS), or license suspension or revocation resulting from a DWI arrest — in Missouri or any other state. Prior contacts don't expire — a DWI from 20 years ago still counts.

The Path to a Felony DWI

A second DWI is still a misdemeanor — but a third offense becomes a felony. If you're facing a second DWI, the outcome of this case directly affects what happens if there's ever a third. A conviction now means a third offense would be charged as a Class E felony (1–4 years in prison) or a Class D felony (1–7 years) depending on the number of priors. Fighting the second offense aggressively isn't just about this case — it's about protecting yourself from dramatically worse consequences down the road.

Frequently Asked Questions About Second-Offense DWI

Will I go to jail for a second DWI?
Missouri law requires a minimum of 10 days in jail or 30 days of community service for a second DWI conviction. This is mandatory — the judge cannot waive it. Actual jail sentences can be longer depending on the facts and the jurisdiction.
How long will I lose my license?
A second alcohol-related offense results in a 5-year revocation of your driving privileges. You may be eligible for a restricted license with an ignition interlock device after a waiting period, but the revocation period is dramatically longer than for a first offense.
Does a DWI from years ago still count as a prior?
Yes. Missouri does not have a lookback period for DWI priors. A DWI conviction or alcohol-related enforcement contact from 10, 15, or 20+ years ago still counts as a prior offense and elevates a new DWI to second-offense status.
What is an ignition interlock device?
An IID is a breathalyzer installed in your vehicle that requires you to blow into it before the engine will start. If alcohol is detected, the vehicle won't start. IIDs are commonly required as a condition of obtaining a restricted driving privilege during the revocation period for second and subsequent DWI offenses.
What happens if I get a third DWI?
A third DWI becomes a felony — either a Class E felony (1–4 years) or a Class D felony (1–7 years) depending on the number of prior contacts. The license revocation extends to 10 years. Fighting the second offense aggressively is critical to preventing felony exposure on any future charge.
Can a second DWI be beaten?
Yes. The same defenses that apply to first-offense DWI — challenging the stop, the field sobriety tests, the breath test, and probable cause — apply with equal force to second offenses. The State still has to prove every element, and there are multiple points where the case can break down. Call The Hartley Law Firm at 816-451-0909.
