DWI courts (sometimes called DUI courts) are a form of court that exists in some United States legal jurisdictions, that use substance-abuse interventions and treatment with defendants who plead guilty of driving while intoxicated or impaired. DUI courts may focus on repeat offenders and drivers with very high levels of blood alcohol at the time of the offense. As of December, 2011, there were approximately 192 designated DUI courts in the United States, and approximately 406 drug courts that also accept DUI offenders.
The term DWI stands for driving while intoxicated, while the term DUI stands for driving under the influence. Both charges relate to operating a motor vehicle while impaired as the result of the consumption of alcohol or another intoxicant. The name given to a DWI court may vary depending upon the terminology used in the state for its impaired driving offenses.
DWI courts tend to focus on the most serious cases and repeat offenders, and thus apply strict standards to the cases and defendants that come before them. Drunk and impaired driving offenses involves a substantial risk of harm and death to the driver and to others, as a foreseeable consequence of such conduct. In 1996, DWI cases accounted for 32 percent of motor vehicle traffic fatalities in the United States In 2014, alcohol was involved in 9,967 motor vehicle accident deaths, accounting for 31 percent of all traffic fatalities.
It is estimated that 6.2 percent of adults aged eighteen and older have an alcohol use disorder, characterized by an impaired ability to stop or control alcohol use.  DWI courts focus on defendants who are deemed at high risk of re-offending if given a less intensive disposition. DWI courts seek to reduce impaired driving by treating alcoholism, while requiring offenders to take responsibility for their actions.
Studies suggest that DWI Courts reduce both DWI recidivism and general criminal recidivism by an average of more than twelve percent, with the most successful DWI courts reducing recidivism by as much as fifty to sixty percent as compared to other forms of sentencing.

When defining DWI offenses, states and courts must consider whether or not the charge or a specific drunk driving offense should be classified as a crime of violence. If a court rules the incident as a crime of violence, which would result in the charge being treated as an "aggravated" felony for purposes if immigration law.
