Sadly, the simple truth is that tens of millions of people actually choose to operate a vehicle while under the influence of alcohol or drugs. Doing so not merely puts one's life at risk and puts passengers among others at risk at the same time, but being caught driving drunk (DUI) or driving while intoxicated (DWI) will almost always cause severe penalties including driver's license suspension or cancellation, monetary penalties and also incarceration. Quite often somebody who has been found guilty of DUI or DWI ultimately has an underlying substance abuse problem. A legal court system knows this, and is therefore inclined to offer DUI and DWI Offenders drug and alcohol rehabilitation as an alternative to other serious consequences because of their crime. Agreeing or obliging to participate in drug and alcohol rehabilitation as a DUI/DWI Offender may not completely get rid of other effects from the crime, but tends to decrease the severity of such penalties to a large degree. Particularly if the individual willingly participates alcohol and drug rehabilitation and is also a first time offender. Studies show that a large proportion of people who do receive drug rehabilitation for a DUI/DWI offense stay out of the courts for comparable charges in the future.
