DUI/DWI is the offence committed when an individual operate or drive a motor vehicle while being under the influence of drugs or alcohol, to such an extent that such individual’s motor and mental skills are weakened. The detailed criminal offence is termed “driving under the influence” (DUI), but in some states within the USA it is termed DWI (driving while intoxicated), OWI (operating while impaired) or OVI (operating a vehicle under the influence). These laws can be applicable to piloting any type of aircraft as well as boating, while the term “vehicles” include horse-drawn carriages and farm machinery.
DUI is illegal in all 50 states of the USA, but the enforcement thereof varies significantly within and between territories and/or states. The District of Columbia have an additional law that state it is illegal to drive a vehicle with a BAC (blood alcohol concentration) exceeding 0.08%.
Upon a positive conviction for a DUI, an individual’s license can be revoked or suspended. In terms of the Administrative License Suspension procedure, a license can be taken from a driver before a conviction when such driver refused or failed to be subject to a chemical test. Due to the fact that Administrative License Suspension laws are impartial of any criminal procedures and invoked directly after an individual was arrested, this procedure is highly regarded as being more successful than conventional sanctions invoked after a conviction.
