Unfortunately, it is a fact that millions of people make the decision to drive a vehicle while under the influence of alcohol or drugs. Doing this not simply puts one's life at risk and puts passengers in danger also, but being caught driving under the influence (DUI) or driving while intoxicated (DWI) will usually lead to severe penalties including driver's license suspension or cancellation, monetary penalties and even jail time. Quite often 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 and alcohol rehabilitation as an alternative to other severe consequences for his or her crime. Agreeing or obliging to participate in alcohol and drug rehab as a DUI/DWI Offender may not completely eliminate other effects of the crime, but can decrease the degree of such consequences to some great extent. Particularly if the individual willingly participates drug rehabilitation and is also a first time offender. Studies have shown that a large percentage of those who do receive drug and alcohol treatment because of a DUI/DWI offense stay out of the court system for similar charges later on.
