DUI and DWI are abbreviated forms of legal terms “driving under the influence” and “driving while intoxicated” respectively. In all jurisdictions around the world, anyone caught driving while not sober will be either fined or jailed depending upon the laws of the country. These laws are just not implied at the time of an accident, regardless of the degree of accident, if a police officer stops and checks a driver who he believes to be under the influence of alcohol, any further drugs test proves the authenticity of the charge.
Since the full form of both these abbreviations mean the same, many people get confused in the difference between DUI and DWI. By law, in my many countries, both of these allegations are used for the same purpose and have no difference. However, in many other jurisdictions, DUI is used to charge someone who was under the influence of alcohol and/or drugs while DWI is used to charge someone who was intoxicated by only alcohol and no drug was present in his or her system.
None the less, both these charges mean that the driver is not in a fit position to drive and despite being aware of this he/she chose to drive in such form and hence he/she must be held accountable for flouting safe motoring rules. These penalties may be only monetary or both monetary and custodial.
In the past years, the number of traffic violations has increased tremendously and the corresponding death toll have also risen significantly. Hence putting the difference between DUI and DWI aside, if we are under any sort of influence that has led us to not be in the right state of mind, we as morally responsible human beings should avoid driving.
