Regrettably, it is a fact that millions of people make the decision to operate a vehicle while under the influence of alcohol or drugs. Doing so not merely puts one's life in danger and puts passengers in danger also, 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, fines as well as incarceration. In many cases someone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse challenge. A legal court system knows this, and it is therefore inclined to offer DUI and DWI Offenders drug and alcohol treatment rather than other severe penalties for his or her crime. Agreeing or obliging to take part in drug rehab as a DUI/DWI Offender might not completely eliminate other penalties of the crime, but can decrease the severity of such penalties to some great extent. Specifically if the individual willingly participates drug rehab and is also a first time offender. Studies show that a large proportion of people who do receive drug and alcohol treatment for a DUI/DWI offense avoid the court system for comparable charges down the road.
