Unfortunately, it's true that millions of people actually choose to drive a vehicle while intoxicated by alcohol or drugs. Doing this not only puts one's life in danger and puts passengers among others in danger also, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will typically result in severe penalties including driver's license suspension or cancellation, monetary penalties and also prison time. Sometimes someone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse issue. A legal court system knows this, and it is therefore inclined to offer DUI and DWI Offenders drug and alcohol rehabilitation instead of other extreme penalties because of their crime. Agreeing or obliging to participate in drug and alcohol treatment as a DUI/DWI Offender may not completely get rid of other effects from the crime, but can decrease the severity of such penalties to a large degree. Specifically if the person willingly participates in drug and alcohol treatment and is also a first time offender. Studies show that a large percentage of folks who do receive drug and alcohol rehab for a DUI/DWI offense stay out of the court system for similar charges down the road.
