Yes. In Mississippi, you can be charged with a DUI if law enforcement reasonably believes your driving was impaired by a legally prescribed medication. The law focuses on whether your ability to operate a vehicle safely was affected rather than the legality of the medication itself, so having a prescription does not automatically prevent charges. Officers typically base probable cause on observed driving behavior, field sobriety tests, and their observations during the stop. It is important to document when and how you took the medication and to preserve pharmacy and medical records that show dosing and physician instructions. After an arrest, gathering medical documentation and consulting with counsel promptly is important because timelines for administrative hearings and evidence preservation are strict. A well-documented explanation of lawful medication use, combined with careful review of the arrest and testing procedures, can often lead to reduced charges or favorable resolutions. In Corinth, addressing both the criminal charge and any separate administrative license matters quickly increases the chance to limit short-term and long-term impacts on driving privileges.
