Sadly, it's true that millions of people choose to drive a vehicle while under the influence of drugs or alcohol. Doing this not only puts one's life at risk and puts passengers and others at risk also, but being caught driving drunk (DUI) or driving while intoxicated (DWI) will more often than not result in severe penalties including driver's license suspension or cancellation, fines and also jail time. Often times a person who has been found guilty of DUI or DWI ultimately struggles with an underlying substance abuse problem. The court system knows this, and is therefore inclined to provide DUI and DWI Offenders drug rehab instead of other severe penalties for their crime. Agreeing or obliging to take part in alcohol and drug rehab as a DUI/DWI Offender may not completely eliminate other effects of the crime, but tends to decrease the severity of such penalties to a great extent. Particularly if the individual willingly participates drug rehabilitation and is a first time offender. Studies have shown that a large proportion of people who do receive alcohol and drug treatment because of a DUI/DWI offense avoid the court system for similar charges in the future.
