Sadly, the simple truth is that millions of people decide to drive a vehicle while intoxicated by drugs or alcohol. This not simply puts one's life in danger and puts passengers in danger at the same time, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will usually result in serious penalties including driver's license suspension or cancellation, monetary penalties and also incarceration. Quite often a person who has been found guilty of DUI or DWI ultimately has an underlying substance abuse problem. A legal court system knows this, and is therefore inclined to offer DUI and DWI Offenders drug and alcohol rehab rather than other serious penalties for his or her crime. Agreeing or obliging to participate in alcohol and drug rehabilitation as a DUI/DWI Offender might not completely eradicate other penalties from the crime, but sometimes decrease the severity of such penalties to a large degree. Specifically if the individual willingly participates in drug treatment and is a first-time offender. Studies have shown that a large proportion of people who do receive alcohol and drug rehab because of a DUI/DWI offense avoid the courts for comparable charges down the road.
