A person can face a DUI charge even if they took a prescription medication exactly as prescribed if evidence indicates that the medication impaired their driving ability at the time of operation. Courts focus on whether the medication materially affected reaction time, coordination, or judgment while driving in Quitman. Documentation of lawful use and medical advice can be critical to the defense, but presence of medication alone does not automatically clear the charge. Explaining timing, dosage, and medical instructions can help create context for laboratory findings and officer observations. If you have documentation showing prescribed use and any warnings provided by the prescriber, gather those records and share them with your attorney. Such records help craft arguments that lawful medical use does not equate to criminal impairment. In some situations, medical notes or pharmacist records establish that a medication should not have produced impairment at the measured levels, providing a basis to challenge the prosecution’s interpretation of toxicology results in Clarke County court proceedings.
