Yes. In Mississippi, breath and blood test results can be challenged on legal and technical grounds. Courts consider whether the device was operated and maintained properly, whether the sample handling and laboratory procedures complied with standards, and whether the stop, arrest, or testing complied with constitutional protections. A successful challenge can lead to suppression of test evidence or other favorable outcomes. Challenging test results requires gathering relevant documentation, including device maintenance logs, operator training records, calibration certificates, and laboratory reports. Local practices in Clarksdale and Coahoma County, as well as statutory deadlines for administrative hearings, play an important role. Prompt review and strategic action are necessary to preserve claims and present effective arguments.
