A Missouri DWI conviction does not have an expiration date. It doesn’t drop off after five, seven, or ten years. One narrow statute allows a first offense to be erased if you file a petition and convince a judge. Otherwise, everything stays where it is.
A DWI Creates Two Separate Records
The criminal case in a circuit or municipal court is a record. The actions taken by the Department of Revenue against your license are another. They operate on separate tracks and different timelines, and resolving one does not help with the other.
The administrative side usually moves first. It also proceeds even if the ticket is later reduced or dismissed in court, which is why people are often stunned to find their license already suspended while the criminal charge is still pending.
Points Fade. The Conviction Does Not.
Missouri reduces points for drivers who remain clean: by one third after one year, half after two years, and to zero after three years. This reduction applies only to the total number of points. The Department of Revenue explicitly states that certain convictions will remain permanently listed on a Missouri driver’s record, including intoxication-related convictions.
The license consequences build on themselves. A second intoxication-related conviction normally brings a one-year revocation, no matter how much time separates the two. A third within five years can bring a five-year license denial, and three or more convictions can bring a ten-year denial.
Missouri’s General Expungement Law Leaves DWI Out
Section 610.140 is the statute that most people have heard about, and it became friendlier in 2025. The waiting period was reduced to one year after a misdemeanor conviction and three years after a felony conviction, with lifetime limits increased to three misdemeanors and two felonies.
None of that helps here. Traffic and boating offences related to intoxication are excluded from this statute outright. Driving while intoxicated has its own separate path, and the penalties are stricter.
The Ten-Year Path
RSMo § 610.130 allows for the expungement of one alcohol-related driving offense in a lifetime, provided that all requirements are met:
- The offense was your first intoxication-related traffic or boating offense charged as a misdemeanor or a city or county ordinance violation. A felony DWI (driving while intoxicated) does not qualify for expungement.
- Ten years have passed since the guilty plea or conviction. No subsequent intoxication-related convictions since then. A second DWI within fifteen years after the first still prevents eligibility for expungement of the first offense.
- No later alcohol-related law enforcement contacts. This includes administrative suspensions and refusal to submit to breath or blood tests that did not result in a criminal charge.
- No commercial driver’s license at the time of the offense or currently.
Nothing happens automatically when a decade passes. Instead, you must file in the court where the offense occurred, and the prosecuting attorney may object.
Old Convictions Keep Counting Against New Charges
Prior offender status uses a five-year window. Nothing above it does. Two traffic offenses related to intoxication committed on separate occasions at any point in your life make the next one a felony and the ladder continues with persistent, aggravated and chronic offender status. Municipal ordinance convictions count. A case from decades ago can turn today’s arrest into a felony.
The Best Time to Protect Your Record Is Now
Because expungement is so narrow, the first few weeks of a DWI case determine more than anything else that happens a decade later. Charges reduced, evidence suppressed, or cases dismissed leave nothing to erase.
