Unfortunately, it is a fact that tens of millions of people decide to drive a vehicle while under the influence of drugs or alcohol. This not just puts one's life in danger and puts passengers at risk also, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will typically lead to severe penalties including driver's license suspension or cancellation, monetary penalties and in many cases prison time. Sometimes anyone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse issue. The court system understands this, and is therefore inclined to offer DUI and DWI Offenders drug and alcohol rehab as an alternative to other severe consequences because of their crime. Agreeing or obliging to take part in drug and alcohol rehab as a DUI/DWI Offender may not completely eradicate other effects from the crime, but tends to decrease the seriousness of such consequences to some large degree. Specifically if the person willingly participates drug rehabilitation and is also a first-time offender. Studies have shown that a large proportion of those who do receive drug treatment for a DUI/DWI offense avoid the courts for comparable charges later on.
