Unfortunately, the simple truth is that millions of people choose to operate a vehicle while intoxicated by alcohol or drugs. This not only puts one's life in danger and puts passengers and others in danger too, 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, fines and even incarceration. Quite often somebody 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 rehab instead of other extreme consequences for crime. Agreeing or obliging to participate in drug and alcohol rehab as a DUI/DWI Offender might not exactly completely eliminate other penalties of the crime, but sometimes decrease the severity of such consequences to some great extent. Particularly if the individual willingly takes part in drug and alcohol treatment and is a first-time offender. Studies have shown that a large proportion of people who do receive drug and alcohol treatment for a DUI/DWI offense avoid the courts for similar charges down the road.
