Unfortunately, the simple truth is that millions of people make the decision to drive a vehicle while under the influence of alcohol or drugs. Doing this not only puts one's life in danger and puts passengers and others at risk as well, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will usually bring about serious penalties including driver's license suspension or cancellation, fines as well as prison time. Quite often anyone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse issue. A legal court system knows this, and is therefore inclined to offer DUI and DWI Offenders drug and alcohol rehabilitation rather than other serious consequences for his or her crime. Agreeing or obliging to participate in drug and alcohol rehab as a DUI/DWI Offender may not completely get rid of other effects from the crime, but can decrease the seriousness of such consequences to a large degree. Particularly if the person willingly takes part in drug and alcohol rehabilitation and is also a first time offender. Research indicates that a large proportion of those who do receive alcohol and drug rehab because of a DUI/DWI offense avoid the court system for similar charges down the road.
