Missouri Law on Prescription Drug DWI’s: Under RSMo. § 577.010, impairment due to any substance — including legally prescribed medications — can result in a DWI charge. The law focuses on whether your ability to operate a vehicle was compromised, regardless of the source of the impairment.
Perhaps the most common legally prescribed medication that leads to DWI’s is Ambien. Also known as Zolpidem, Ambien is used to treat insomnia and can cause drowsiness, dizziness, and impaired judgment.
At Rose Legal Services, we have represented several clients in DWI-Ambien cases, and even when the motorist has a valid prescription, driving while impaired by Ambien is just as illegal as driving while impaired by alcohol.
Real-World Example: In Missouri v. Clarkston, a Missouri resident taking prescribed insulin was stopped for erratic driving. Although they were following their doctor’s instructions, their case highlighted the need for medical records and expert testimony to explain the situation, ultimately leading to a favorable outcome.
So, if you’re taking prescription medications, consult your doctor about potential side effects and avoid driving if you feel impaired.
If you’re charged with a DWI, an experienced attorney can help you build a defense by examining factors such as dosage, medical necessity, and testing methods.
