In Mississippi, driving under the influence (DUI) occurs when a person operates a motor vehicle while impaired by alcohol, drugs, or other substances. DUI charges may be based on blood alcohol concentration (BAC), observed impairment, or a combination of factors evaluated by law enforcement during a traffic stop or investigation.
DUI arrests often stem from routine traffic stops, sobriety checkpoints, or accident investigations. Law enforcement officers may rely on field sobriety tests, breath testing, or blood analysis to determine impairment. Each of these methods is subject to specific legal requirements and procedures under Mississippi law.
