Driving Under Influence (DUI) and DUI Attorneys

In the United States the National Highway Traffic Safety Administration (NHTSA) estimates that 17,013 people died in 2003 in "alcohol-related" collisions, representing 40 percent of total traffic deaths in the US. Over 500,000 people were injured in alcohol-related accidents in the US in 2003. NHTSA defines fatal collisions as "alcohol-related" if they believe the driver, a passenger, or a nonoccupant of the vehicle (such as a pedestrian or pedalcyclist) had a blood alcohol content (BAC) of 0.01 or greater. NHTSA defines nonfatal collisions as "alcohol-related" if the accident report indicates evidence of alcohol present. NHTSA specifically notes that "alcohol-related" does not necessarily mean a driver or nonoccupant was tested for alcohol and that the term does not indicate a collision or fatality was caused by the presence of alcohol.

Laws:
All states in the U.S. designate a "per se" blood or breath alcohol level as the threshold point for an independent criminal offense. A second criminal offense of driving "under the influence" or "while impaired" is also usually charged in most states, with a permissive presumption of guilt where the person's blood alcohol concentration (BAC) is .08 percent or greater (units of milligrams per deciliter, representing 8 g of alcohol in 100 deciliters of blood). Some states (e.g., Colorado) include a lesser charge, sometimes referred to as driving while ability impaired (this may apply to individuals with a .05 percent or above, but less than the .08 per se limit for the more serious charge. Prior to wider emphasis on drinking and driving in the 1980s, standards of .10-.15 percent were in place.

Federal Air Regulation 91.17 (14 CFR 91.17) prohibits pilots from flying aircraft with an alcohol level of 0.04% or more, and/or within eight hours of consuming alcohol, and/or while under the impairing influence of any drug. The same prohibition applies to any other crewmembers on duty aboard the aircraft  (flight attendants, etc.). Some airlines impose additional restrictions, and many pilots also impose stricter standards upon themselves. Commercial pilots found to be in violation of regulations are typically fired or resign voluntarily, and they  may lose their pilot certificates and/or be subject to criminal prosecution under Federal or State laws, effectively ending their careers.

Unlike DUI, DWI, or OWUI cases that involve alcohol, there is generally no "per se"  or legal limit that is employed for persons accused of driving under the influence of prescription medication or illicit drugs (although this is not the case in Ohio. Instead, the key inquiry focuses on whether the driver's faculties were impaired by the substance that was consumed. The detection and successful prosecution of drivers impaired by prescription medication or illegal drugs can therefore be difficult. Similarly, although urinalysis toxicology screens can detect the presence of such substances in the driver's bloodstream, these analyses are unable to demonstrate that the substance was actually causing impairment at the time of driving.In response to these problems.

Many jurisdictions require more serious penalties (such as jail time, larger fines, longer DUI program, the installation of ignition interlock devices) in cases where the driver's BAC is over 0.20, or 0.15 in some places. These additional sanctions are an attempt to deter and punish the operation of a vehicle at extremely high BAC levels and the concomitant danger posed to the safety of persons and property by heavily impaired drivers. In many cases, the reason given for these additional sanctions is because an average person would have passed out from that much alcohol.
