Sadly, it's true that tens of millions of people decide to operate a vehicle while under the influence of drugs or alcohol. Doing this not simply puts one's life at risk and puts passengers among others at risk too, but being caught driving under the influence (DUI) or driving while intoxicated (DWI) will almost always cause serious penalties including driver's license suspension or cancellation, monetary penalties and even incarceration. Sometimes a person who has been found guilty of DUI or DWI ultimately has an underlying substance abuse issue. A legal court system understands this, and is therefore inclined to provide DUI and DWI Offenders drug and alcohol rehab rather than other extreme penalties for his or her crime. Agreeing or obliging to participate in drug rehab as a DUI/DWI Offender might not exactly completely eliminate other effects of the crime, but tends to decrease the seriousness of such consequences to a large degree. Specifically if the person willingly participates in drug and alcohol rehabilitation and is also a first-time offender. Research has shown that lots of those who do receive drug and alcohol rehabilitation because of a DUI/DWI offense avoid the court system for similar charges later on.
