Overview
Kansas has steadily toughened its DUI laws, most recently with significant reforms that made third-offense DUI a nonperson felony and expanded ignition interlock device requirements. The state uses a lifetime lookback period — all prior DUI convictions from any time count toward repeat offense enhancements. Kansas is distinctive for its administrative per se suspension system (separate from criminal penalties), its mandatory 48-hour jail or community service for even first offenses, and its requirement that all DUI offenders complete a state-certified alcohol and drug safety action program (ADSAP). A fourth DUI is a nonperson felony carrying up to 1 year in jail with a mandatory minimum of 90 days.

Implied Consent Law
Under K.S.A. §8-1001, Kansas's implied consent law provides that any person operating or attempting to operate a vehicle in Kansas consents to testing of breath, blood, urine, or other bodily substance for alcohol or drugs. An officer with reasonable grounds to believe the driver is impaired must inform the driver of the consequences of refusal before requesting a test.
Refusal penalties: First refusal: 1-year license suspension (no driving for first 90 days, then IID-restricted for remaining 9 months). Second or subsequent refusal: 1-year suspension with no driving for first year, then 2–10 year IID restriction. Refusal is admissible as evidence in the criminal DUI proceeding. Kansas treats refusal as an aggravating factor for sentencing.
Aggravating Factors
| Factor | Impact |
|---|---|
| BAC of 0.15% or higher | Extended license suspension (doubled) and longer IID requirement periods; used as aggravating factor at sentencing |
| Child passenger under 14 | Separate charge of child endangerment; enhanced sentencing; possible involvement of Department for Children and Families (DCF) |
| Causing great bodily harm | Felony charge — aggravated battery or vehicular battery; up to 13 months in prison for first conviction plus DUI penalties |
| Causing death (vehicular homicide) | Involuntary manslaughter (severity level 5 person felony); 55–247 months in prison depending on criminal history; mandatory incarceration |
| Driving on a DUI-suspended or revoked license | Additional criminal charge; treated as a subsequent DUI offense for penalty purposes; mandatory jail time |
| Refusing chemical testing | Enhanced license suspension; IID requirement; refusal used as evidence of impairment at trial |
DUI with Injury
Classification: Felony — aggravated battery or involuntary manslaughter depending on severity
DUI causing great bodily harm (aggravated battery): severity level 4–7 person felony depending on circumstances, 13–172 months in prison under sentencing guidelines. DUI causing death (involuntary manslaughter): severity level 5 person felony, 55–247 months in prison depending on criminal history. Vehicular homicide while DUI: up to 172 months. All carry mandatory restitution and permanent license consequences.
Underage DUI
Drivers under 21 with BAC of 0.02% to 0.079% face a 30-day license suspension for a first violation and a 1-year suspension for a second violation under the underage drinking and driving statute (K.S.A. §8-1567a). Must complete ADSAP. If BAC reaches 0.08%, full adult DUI penalties apply. Separate penalties under Kansas's minor in possession laws may also apply.
Diversion Programs
Program: DUI Diversion Agreement
Kansas has a unique DUI diversion system under K.S.A. §8-1567 and §22-2906 through §22-2911. A diversion agreement is a contract between the offender and the prosecutor where the criminal charges are held in abeyance while the offender completes conditions including substance abuse evaluation and treatment, victim impact panel, community service, and a supervision period of 1 year. If completed, charges are dismissed.
Eligibility: DUI diversion is generally available for first-time DUI offenders who have never previously received a diversion for DUI. Important: a prior diversion counts as a prior offense if you get another DUI — it still triggers enhanced penalties for subsequent offenses. The prosecutor has discretion to offer or deny diversion. Some counties have specific eligibility criteria regarding BAC level and circumstances.
How Long a DUI Stays on Your Record
A DUI conviction in Kansas stays on your criminal record permanently. Kansas does not allow expungement of DUI convictions until 5 years after completion of the sentence for misdemeanor DUI, or 3 years after completion for diversion. However, even an expunged DUI or completed diversion counts as a prior offense for the lifetime lookback if you are charged with DUI again. Your driving record with the Kansas DMV retains DUI information permanently.
