Regrettably, it is a fact that millions of people choose to drive a vehicle while under the influence of drugs or alcohol. Doing so not just puts one's life in danger and puts passengers and others in danger as well, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will more often than not bring about severe penalties including driver's license suspension or cancellation, monetary penalties and in many cases jail time. Often times someone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse issue. The court system knows this, and is therefore inclined to offer DUI and DWI Offenders alcohol and drug treatment instead of other serious penalties for crime. Agreeing or obliging to take part in alcohol and drug rehabilitation as a DUI/DWI Offender may not completely eliminate other effects from the crime, but tends to decrease the seriousness of such consequences to some great extent. Particularly if the individual willingly participates drug rehab and is a first-time offender. Studies show that a large proportion of individuals who do receive alcohol and drug rehab because of a DUI/DWI offense stay out of the courts for similar charges down the road.
