In Kansas, there’s no legal difference between a DUI (Driving Under the Influence) and a DWI (Driving While Intoxicated). The state uses the term DUI for all impaired driving offenses, covering both alcohol and drug-related impairment. While some states separate the two terms based on substance or severity, Kansas law treats them the same, meaning any level of intoxicated or drug-impaired driving can result in a DUI charge.

DUI Under Kansas Law

Under K.S.A. 8-1567, a DUI occurs when a person operates or attempts to operate a vehicle while impaired by alcohol, drugs, or a combination of both. The law applies to any impairment that affects safe driving ability.

• Blood Alcohol Concentration (BAC) – 0.08% or higher for adults is automatic DUI.
• Drug impairment – Includes illegal drugs, prescription medications, or other substances affecting judgment or coordination.
• Applies to any vehicle – Cars, trucks, motorcycles, and sometimes other motorized vehicles.

DWI in Other States

Some states use DWI to mean “Driving While Intoxicated” or “Driving While Impaired.” In those states, DWI can indicate a higher level of intoxication than DUI, or it might apply specifically to alcohol, while DUI applies to drugs. Kansas does not make that distinction.

• DWI vs. DUI – Other states separate them, but Kansas combines both under DUI law.
• One unified charge – Whether alcohol, drugs, or both, it’s always charged as DUI in Kansas.
• Legal terminology – “DWI” isn’t used in Kansas court filings or criminal codes.

Penalties for DUI in Kansas

The penalties for DUI depend on how many prior offenses you have and your BAC level. Even a first-time offense can carry serious consequences, including jail time, fines, and license suspension.

• First offense – Up to 6 months in jail, $750–$1,000 fine, and license suspension for 30 days.
• Second offense – 90 days to 1 year in jail, $1,250–$1,750 fine, and 1-year license suspension.
• Third offense – Felony charge with longer jail time, higher fines, and possible vehicle impoundment.
• Ignition interlock device – Required after suspension for most offenders.

DUI Testing and Arrest

Police determine impairment through field sobriety tests, breath tests, or blood tests. Refusing to take a chemical test triggers automatic penalties under Kansas’ implied consent law.

• Refusal penalties – Automatic 1-year license suspension, even without a conviction.
• Blood and urine testing – Used when drug impairment is suspected.
• Probable cause – Officers must have reasonable suspicion before conducting tests or making an arrest.

How Kansas Differs From Other States

Kansas uses only the term DUI, unlike other states that distinguish between DUI and DWI. The penalties, testing methods, and enforcement apply uniformly to all impaired driving cases, regardless of the substance involved.

• One charge type – DUI covers both alcohol and drug impairment.
• No DWI category – DWI is not recognized in Kansas courts.
• Same penalties for all impairment types – Drug-based or alcohol-based offenses are treated equally.

In Kansas, there’s no difference between DUI and DWI both refer to driving under the influence of alcohol or drugs. The law uses only “DUI,” and penalties depend on prior offenses and level of impairment.
