There are various criminal charges for operating a motorized, electric, or otherwise-powered transportation device on public roadways or waterways while under the influence of or intoxicated by drugs or alcohol, as defined by state law. DUI, DWI, OUI, OWI, and BUI—driving under the influence, driving while intoxicated, operating under the influence, operating while intoxicated, and boating under the influence—are some of the common names for such impaired-driving or impaired-operating criminal offenses.

Laws regarding the definitions and names of such alcohol and drug-related driving offenses vary from state to state and are usually located in a state’s statutes—often in the penal code or criminal code.

In Georgia, the primary offense for operating a vehicle while under the influence of alcohol or drugs is known as Driving Under the Influence (DUI). Georgia law prohibits driving or being in actual physical control of any moving vehicle while under the influence of alcohol, drugs, whether legal or illegal, or a combination of both, to the extent that it is less safe for the person to do so. The legal blood alcohol concentration (BAC) limit in Georgia is 0.08% for drivers over the age of 21 operating standard passenger vehicles. For commercial drivers, the limit is 0.04%, and for drivers under the age of 21, the limit is 0.02%. Penalties for DUI can include fines, imprisonment, community service, DUI school, and license suspension. Georgia also has an implied consent law, meaning that by driving on Georgia roads, drivers have consented to chemical testing to determine BAC or the presence of drugs. Refusal to submit to testing can result in license suspension. For boating, the offense is known as Boating Under the Influence (BUI), and it carries similar prohibitions and penalties for operating watercraft while impaired.
