Sadly, it's true that tens of millions of people actually choose to drive an automobile while under the influence of alcohol or drugs. This not simply puts one's life in danger and puts passengers among others in danger too, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will almost always cause serious penalties including driver's license suspension or cancellation, fines as well as incarceration. Sometimes anyone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse challenge. The court system knows this, and is therefore inclined to offer DUI and DWI Offenders alcohol and drug rehabilitation instead of other serious penalties for his or her crime. Agreeing or obliging to participate in drug and alcohol rehabilitation as a DUI/DWI Offender might not exactly completely eliminate other effects of the crime, but tends to decrease the degree of such penalties to some large degree. Specifically if the person willingly participates in drug rehab and is a first time offender. Studies have shown that lots of those who do receive drug and alcohol rehab because of a DUI/DWI offense stay out of the courts for comparable charges in the future.
