Regrettably, it is a fact that millions of people decide to operate a vehicle while intoxicated by drugs or alcohol. This not just puts one's life in danger and puts passengers and others at risk also, but being caught driving under the influence (DUI) or driving while intoxicated (DWI) will usually lead to serious penalties including driver's license suspension or cancellation, fines and in many cases incarceration. In many cases a person who has been found guilty of DUI or DWI ultimately has an underlying substance abuse issue. The court system understands this, and is therefore inclined to offer DUI and DWI Offenders drug treatment instead of other extreme consequences for his or her crime. Agreeing or obliging to take part in drug rehabilitation as a DUI/DWI Offender might not completely eliminate other penalties of the crime, but sometimes decrease the seriousness of such consequences to some large degree. Particularly if the person willingly takes part in drug treatment and is also a first-time offender. Studies have shown that a large proportion of people who do receive drug and alcohol rehab because of a DUI/DWI offense stay out of the court system for similar charges later on.
