Driving While Intoxicated is the offense of operating a motor vehicle while under the influence of alcohol or drugs. State law controls whether operating includes actual driving of the car or merely sitting in the car and the level of intoxication needed in order to be found in violation of the law. Some statutes refer to driving under the influence (DUI) or driving while impaired (DWI) that does not require intoxication. DUI and DWI lawyers represent people who have been arrested and charged with driving under the influence of alcohol or drugs. DUI and DWI attorneys defend clients at each stage of a DUI or DWI case -- from arrest to an appeal after conviction. A DUI and DWI attorney may challenge aspects of a DUI or DWI arrest or conviction, including breathalyzer and chemical testing procedures.
Dallas, with a population of 1.2 million is the third-largest city in Texas and the eighth-largest in the United States. The city is the primary economic center of the 12-county Dallas–Fort Worth–Arlington metropolitan area that according to the March 2009 U.S. Census Bureau release, had a population of 6.3 million as of July 2008. The metropolitan area is the fourth-largest metropolitan area in the United States. Founded in 1841 and formally incorporated as a city in February, 1856, the city's economy is primarily based on banking, commerce, telecommunications, computer technology, energy, and transportation; only New York City and Houston are home to more Fortune 500 headquarters in the city limits. Located in North Texas and a major city in the American South/Southwest, Dallas is the core of the largest inland metropolitan area in the United States that lacks any navigable link to the sea. The city's prominence despite this comes from its historical importance as a center for the oil and cotton industries, its position along numerous railroad lines, a strong industrial and financial sector, and its status as a major inland port (due largely to the presence of Dallas/Fort Worth International Airport, one of the largest and busiest in the world). It was rated as a beta world city by the Globalization and World Cities Study Group & Network.
