Unfortunately, the simple truth is that millions of people decide to drive a vehicle while under the influence of drugs or alcohol. This not merely puts one's life in danger and puts passengers and others at risk at the same time, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will almost always lead to severe penalties including driver's license suspension or cancellation, monetary penalties and even incarceration. Quite often somebody 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 consequences for his or her crime. Agreeing or obliging to take part in drug treatment as a DUI/DWI Offender might not exactly completely eliminate other penalties of the crime, but tends to decrease the degree of such consequences to some large degree. Specifically if the individual willingly participates in alcohol and drug rehab and is also a first time offender. Studies show that a large proportion of folks who do receive alcohol and drug rehabilitation for a DUI/DWI offense stay out of the court system for similar charges down the road.
