Regrettably, it's true that millions of people make the decision to operate a vehicle while under the influence of alcohol or drugs. Doing so not merely 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 more often than not lead to serious penalties including driver's license suspension or cancellation, fines and in many cases jail time. Sometimes someone who has been found guilty of DUI or DWI ultimately has an underlying substance abuse challenge. The court system understands this, and is therefore inclined to provide DUI and DWI Offenders alcohol and drug rehabilitation rather than other serious penalties for their crime. Agreeing or obliging to take part in alcohol and drug rehab as a DUI/DWI Offender might not completely eliminate other effects of the crime, but tends to decrease the severity of such penalties to a large degree. Particularly if the person willingly participates drug and alcohol rehabilitation and is a first time offender. Studies have shown that a lot of those who do receive alcohol and drug rehabilitation because of a DUI/DWI offense stay out of the courts for comparable charges in the future.
