<P> In the United Kingdom, the offense is often known as "drunk in charge of a motor vehicle" or "drunk in charge" due to the wording of the Licensing Act 1872 . In relation to motor vehicles, the Road Traffic Act 1988 creates a narrower offense of driving (or being in charge of) a vehicle while having breath, blood or urine alcohol levels above the prescribed limits (colloquially called "being over the limit"); and a broader offense of "driving while unfit through drink or drugs," which can apply even with levels below the limits . A separate offense in the 1988 Act applies to bicycles . While the 1872 Act is mostly superseded, the offense of being "drunk while in charge...of any carriage, horse, cattle, or steam engine" is still in force; "carriage" has sometimes been interpreted as including mobility scooters . </P> <P> The criminal offense may not involve actual driving of the vehicle, but rather may broadly include being physically in control of a car while intoxicated even if the person charged is not driving . For example, a person found in the driver's seat of a car while intoxicated and holding the keys, even while parked, may be charged with DUI, because he or she is in control of the vehicle . In construing the terms DUI, DWI, OWI and OVI, some states therefore make it illegal to drive a motor vehicle while under the influence or driving while intoxicated while others indicate that it is illegal to operate a motor vehicle . There is a split of authority across the country regarding this issue . Some states permit enforcement of DUI / DWI and OWI / OVI statutes based on "operation and control" of a vehicle, while others require actual "driving". "The distinction between these two terms is material, for it is generally held that the word' drive,' as used in statutes of this kind, usually denotes movement of the vehicle in some direction, whereas the word' operate' has a broader meaning so as to include not only the motion of the vehicle, but also acts which engage the machinery of the vehicle that, alone or in sequence, will set in motion the motive power of the vehicle ." (State v. Graves (1977) 269 S.C. 356 (237 S.E. 2d 584, 586 - 588, 586 . fn. 8). </P> <P> Merriam Webster's Dictionary defines DUI as the "crime of driving a vehicle while drunk; also: a person who is arrested for driving a vehicle while drunk; the act or crime of driving while affected by alcohol or drugs; a person who is arrested for or convicted of driving under the influence or an arrest or conviction for driving under the influence . In some countries (including Australia and many jurisdictions throughout the United States), a person can be charged with a criminal offense for riding a bike, skateboard, or horse while intoxicated or under the influence of alcohol . </P> <P> Drinking enough alcohol to cause a blood alcohol concentration (BAC) of 0.03--0.12% typically causes a flushed, red appearance in the face and impaired judgment and fine muscle coordination . A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision . A BAC from 0.18% to 0.30% causes profound confusion, impaired speech (e.g., slurred speech), staggering, dizziness and vomiting . A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting and respiratory depression (potentially life - threatening). A BAC from 0.35% to 0.80% causes a coma (unconsciousness), life - threatening respiratory depression and possibly fatal alcohol poisoning . </P>
