The availability of DUI arrest records varies based on the jurisdiction of the county, state and country where the individual received the DUI charge. In the United States, there is not a composite database of DUI arrests, as of 2015, but the information is often available on public databases.
In order to find out if an individual has been arrested on DUI charges, the person's full name is needed, in addition to the state or region where the DUI was issued. Some websites may require a date of birth and a current, or previous, address of the individual. Depending on the region, the information may be available at a state or county legislature website. If not, there are various public and private websites and services offer to find the information, such as InstantCheckMate.com.
The quality of information varies from source to source, so it may be beneficial to do some research before choosing one. Some of these services require a fee. If the online search proves unfruitful, there are professional background research companies available, such as the National Association of Professional Background Screeners. Companies like this may have more extensive resources at their disposal than ones that are accessible online for no charge.
