The License Case
A DUI arrest starts two cases: the criminal one above and an administrative one over the license, run by the Department of Public Safety. The driving record, kept by the Mississippi Department of Public Safety Driver Service Bureau, carries the result of both.
The Records a DUI Leaves

- The court file: from the Justice Court or a municipal court, kept by the Circuit Clerk for criminal and civil cases and the Chancery Clerk for divorces, estates and land records.
