Your DWI Is Permanent (Unless You Choose an SIS or Expunge It)
A standard DWI conviction in Missouri remains on your public criminal record for life. Unlike some states that apply lookback windows (for example, a 10-year window for prior enhancement), Missouri imposes no cutoff.
If you are arrested for a second DWI offense in 2035, a 2010 DWI conviction will still count as a “prior” for offender-tier purposes. That permanence is written into RSMo § 577.023, which governs the offender tier framework and does not contain a lookback expiration.
The only ways to break that permanence are:
- Suspended Imposition of Sentence (SIS): Your conviction is held in suspense, and if you complete probation without incident, the case may be dismissed. A dismissed SIS is not a countable prior for future enhancement.
- Expungement: After waiting 10 years, a first misdemeanor DWI may be eligible for expungement under RSMo § 577.054. Expungement seals the public record; you may legally omit the conviction in most applications.
If you receive neither SIS nor expungement, the conviction is permanent, and your criminal record will reflect it indefinitely.
The Department of Revenue’s Permanent Memory
Here is where Missouri’s framework becomes particularly unforgiving: the Department of Revenue maintains DWI records for offender-tier enhancement purposes, and there is no statutory lookback period. RSMo § 577.023 does not say “count priors within 10 years” or “count priors within 20 years.” It says any prior DWI conviction is counted.
This means even if you successfully expunge a public record (removing it from public databases), the Department of Revenue retains the conviction in its internal offender-tier files. If you are arrested again for DWI, the prosecutor will check the DOR records and find your prior, even if a background check would not. The DOR’s memory is not erased by expungement; it only affects public visibility.
This distinction is crucial. You might successfully remove your conviction from view, but the state’s driving record division still “knows” about it and will apply it to any future charge.
What Happens When Employers and Insurers Look You Up
When an employer runs a background check, a standard DWI conviction will appear in Missouri’s criminal history database. There is no expiration date, no lookback period, and no automatic removal. Insurance companies also conduct records checks, and a DWI stays visible for their underwriting.
Many employers and insurers use conviction dates and offense categories to make hiring or coverage decisions. Some positions (commercial driver’s licenses, or CDL; security clearances; certain regulated professions) may carry lifetime disqualifications following a DWI. Even in less-regulated roles, a 10-year-old DWI will show up next to your name as clearly as a recent one.
The only way to remove that public visibility is through expungement (or, in some cases, SIS dismissal). Otherwise, background checks will surface your DWI indefinitely.
The Suspended Imposition of Sentence (SIS) Alternative
An SIS is a negotiated outcome in which the court imposes a sentence but holds it in suspense, provided you complete probation successfully. During the SIS period, the conviction technically exists; it shows on your driving record and to the Department of Revenue for offender-tier purposes. But it does not appear on your public criminal record.
If you complete probation without incident (no new charges, no violations), the charge may be dismissed. Once dismissed, the conviction is no longer a countable prior for offender-tier enhancement. You may then be eligible for immediate expungement, or the case is simply closed without a public conviction record.
This is why an SIS is often more favorable than a straight conviction. You avoid a public criminal record visible to employers and insurers. The Department of Revenue still knows about it during probation, but after dismissal and expungement, the state’s formal offender-tier records are cleared as well.
Can I Automatically Get an SIS if I’m a First-Time Offender?
An SIS is not a right; it must be negotiated, and not all cases qualify. Typically, only first-time DWI offenses qualify for an SIS, and then only if the prosecution or court agrees. An effective DWI defense strategy may be to pursue an SIS aggressively; this avoids public stigma and minimizes long-term record complications.
Expungement Eligibility and Timeline Under RSMo § 577.054
Not everyone is eligible for expungement, and there are strict conditions and waiting periods under RSMo § 577.054.
Eligibility for DWI Expungement in Missouri
You may petition for expungement of a misdemeanor DWI conviction if:
- It is your first DWI conviction, AND
- You had no other DWI or related impaired-driving conviction in the 10 years before your arrest, AND
- You have not been charged with any additional DWI or traffic offense since the conviction.
Additionally, you must wait at least 10 years after the DWI conviction to apply for expungement.
What a DWI Expungment Does
Once expunged, the conviction is removed from public view. You may legally answer “no” if asked whether you have been convicted of a DWI in most contexts. There are narrow exceptions: certain law enforcement and government positions, or if you are charged with another offense (at which point past convictions may be unsealed for that proceeding).
What a DWI Expungment Does Not Do
Expungement does not erase the Department of Revenue’s internal DWI records for offender-tier purposes. If the DOR has documented the conviction in its files, that file remains accessible for calculating offender status in a future arrest.
However, you may have options for expungement of the driving record itself; consult your attorney about the specific DOR procedures.
What Makes Me Ineligible for a DWI Expungement?
You cannot expunge a DWI if:
- You have a prior DWI conviction within 10 years before the arrest date (or any prior felony DWI).
- The offense involved injury, death, or property damage.
- The charge was elevated to a felony (e.g., aggravated DWI).
- You have been convicted of another DWI or traffic offense since the original conviction.
If you are ineligible for expungement, the conviction remains permanent on your public record, though an SIS dismissal still clears the public conviction record.
Why Offense-Tier Enhancement Means Prior Convictions Never Expire
Missouri classifies DWI offenses by the offender tier: first, second, third, fourth or subsequent. The tier determines penalties, license suspension length, and mandatory minimum jail time. Each tier is defined in RSMo § 577.023, and here is the critical detail: the statute lists a “prior” DWI conviction with no lookback expiration.
This contrasts sharply with some federal and state frameworks that apply a lookback window. For example, federal sentencing guidelines may count only priors within 10 or 15 years; some states limit the priors used for enhancement to those within 5 to 15 years.
In Missouri, a 2005 DWI conviction counts toward a 2035 arrest in exactly the same way a 2033 DWI would. The prosecution can argue for an elevated offender tier based on a 30-year-old prior. That prior also appears in the Department of Revenue’s permanent file, visible to prosecutors and driving record administrators, even if a public criminal record has been expunged.
This framework reflects Missouri’s policy on DWI as a serious and persistent hazard. Once convicted, you carry that prior forever, unless the underlying conviction is dismissed (as in an SIS) or expunged (a narrow, multi-year process).
Frequently Asked Questions About Your DWI Record
Can I have my DWI record removed before the 10-year waiting period?
Not automatically. You can petition the court for early expungement if you meet eligibility criteria, but the court may decline. If you received a dismissal through an SIS, then you may be eligible to have your DWI removed prior to the 10-year mark.
If I expunge my DWI, will the Department of Revenue forget about it?
Expungement removes the conviction from public view, but it does not automatically purge the DOR’s offender-tier records. The DOR will still have the conviction listed for enhancement purposes if you are arrested again for DWI. You may petition the DOR for removal of the DWI record from the driving file separately; consult an attorney about that process.
I got an SIS that was dismissed. Can I say I was never convicted?
After the SIS is dismissed, the conviction is no longer a public record, and you may be eligible for immediate expungement. Once expunged, you may legally omit the conviction in most applications. However, certain law enforcement and government employers may still inquire about dismissed charges, so always check the context.
Will my DWI prevent me from getting car insurance forever?
DWI convictions can disqualify you from standard insurance, and some insurers will not cover you for years. However, after expungement (or SIS dismissal), your public record no longer shows the conviction, and insurers may be willing to provide coverage. Rates will likely be higher, but you are not permanently shut out. This depends on the insurer’s underwriting guidelines.
What is the difference between an arrest record and a conviction record?
An arrest record documents that you were taken into custody; it remains on file regardless of the outcome. A conviction record documents that you were found guilty (or pleaded guilty) and sentenced. Only conviction records are eligible for expungement. Arrest records that did not result in a conviction may be subject to different procedures (often faster); consult an attorney about whether your arrest can be sealed separately.
If I move out of Missouri, does my DWI record follow me?
Yes. Other states can access Missouri’s criminal history through national databases, and federal records systems will reflect your Missouri conviction. An out-of-state employer conducting a background check can see your Missouri DWI. Expungement in Missouri may limit visibility in the Missouri system, but other states and federal databases may still retain copies. If you are charged with DWI in another state, Missouri’s prior will be available to prosecutors.
