Driving under the influence (DUI), commonly known as drunk driving, means operating a motor vehicle in a public area while intoxicated. It is considered a criminal offence to drive a vehicle after consuming alcoholic beverages. DUIs are also considered an offense when boating and piloting aircraft.

Driving under the influence of alcohol is a misdemeanor, and depending upon the nature of jurisdiction, it is sometimes referred to as driving while intoxicated (DWI), operating while intoxicated (OWI) or operating a motor vehicle while intoxicated (OMVI). DUI is perhaps one of the main reasons for motor vehicle crashes. The excess use of alcohol impairs the nervous system, thereby adversely affecting the balance of mind and body.

While driving under the influence is regarded as a serious offense in almost all states, the punishment generally depends upon the DUI statute in the state. If you are charged with driving under the influence, blood and urine levels are first tested. Also, a breath test is administered. If it is proved that your blood alcohol content is above the legal limit set by the state's statute, you will be arrested. In some states, if any one is proved to have a breath test of .08 or higher, they are said to be under the influence of alcohol.

In all cases, if you are driving under the influence of alcohol, there is a good chance that you will lose your license, serve time in prison and serve a lengthy probation period. The charge could also affect future employment. DUI laws are quite complex, and offenders generally seek assistance of a competent and experienced lawyer to help them out.

Offenders are generally charged large fines based on the court proceedings and test results. Usually, first-time offenders are charged a fine, and there are certain provisions to get keep punishments at a mimimum.
