Sadly, it's true that millions of people decide to operate a vehicle while intoxicated by drugs or alcohol. Doing this not merely puts one's life at risk and puts passengers among others in danger as well, but being caught driving while impaired (DUI) or driving while intoxicated (DWI) will usually lead to serious penalties including driver's license suspension or cancellation, fines and even 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 is therefore inclined to offer DUI and DWI Offenders alcohol and drug rehabilitation instead of other serious consequences for his or her crime. Agreeing or obliging to participate in alcohol and drug treatment as a DUI/DWI Offender might not exactly completely get rid of other consequences from the crime, but sometimes decrease the degree of such consequences to some great extent. Particularly if the individual willingly participates in drug rehab and is also a first-time offender. Research has shown that a large proportion of people who do receive alcohol and drug rehabilitation for a DUI/DWI offense stay out of the courts for similar charges in the future.
