Can You Get a DUI in Georgia for Prescription Medication?
Answer:
Yes — Georgia’s DUI statute under O.C.G.A. § 40-6-391 applies to any substance that impairs a driver’s ability to operate a vehicle safely, including lawfully prescribed medications. Having a valid prescription is not a defense. The fact that a medication was prescribed by a physician, taken as directed, and in the driver’s possession is legally irrelevant to whether a DUI charge can be maintained. Opioids, benzodiazepines, sleep aids, muscle relaxants, and antihistamines can all form the basis of a DUI charge. However, Georgia law provides one meaningful advantage in prescription drug cases: under O.C.G.A. § 40-6-391(a)(6), when the charge is based on a lawfully prescribed drug, the prosecution must prove the medication rendered the defendant incapable of driving safely — a higher standard than the less safe standard that applies in other drug DUI cases. This distinction carries significant practical weight before a jury.
Yes — Georgia’s DUI statute applies to any substance that impairs a driver’s ability to operate a vehicle safely, including lawfully prescribed medications. Having a valid prescription is not a defense to a DUI charge in Georgia. This surprises many drivers who assume that taking medication as directed by a physician provides legal protection from DUI prosecution. It does not.
The General Rule: A Prescription Is Not a Defense
Under O.C.G.A. § 40-6-391, any substance — alcohol, illegal drugs, or lawfully prescribed medication — can serve as the basis for a DUI charge if it renders the driver a less safe operator of a motor vehicle. The fact that a medication was prescribed by a licensed physician, that the driver was taking it as directed, and that the driver was in possession of the prescription at the time of the stop are all legally irrelevant to whether the DUI charge can be maintained. Georgia courts have been clear that lawful authorization to use a substance does not create a defense to impaired driving.
This means that commonly prescribed medications — opioid pain relievers, benzodiazepines, sleep aids, muscle relaxants, antihistamines, and others with sedating or impairing properties — can all provide the basis for a DUI charge if the government can establish that the driver’s ability to drive safely was affected by the medication.
The Prescription Drug Standard: Incapable of Driving Safely
Although having a prescription does not provide a defense, Georgia law does provide one meaningful advantage for defendants charged with DUI based on a lawfully prescribed medication: the government must meet a higher evidentiary standard. Under O.C.G.A. § 40-6-391(a)(6), when the DUI charge is based on a drug that is lawfully prescribed to the defendant, the prosecution must prove that the drug rendered the defendant incapable of driving safely — not merely that it made them a less safe driver.
This distinction in language — “incapable” versus “less safe” — carries practical weight in front of a jury. While courts have acknowledged that the two standards are not entirely different, presenting a jury with the requirement that the government prove the defendant was rendered incapable of driving safely sets a more demanding benchmark in the minds of jurors evaluating whether the evidence satisfies it. An experienced defense attorney will ensure the jury receives and understands the correct legal standard applicable to a prescription drug case.
Practical Implications for Drivers Taking Prescription Medication
Any driver who takes prescription medications with potential sedating or impairing effects should understand that Georgia’s DUI law creates legal exposure for driving while affected by those medications, regardless of whether the medication was taken as prescribed. The standard for impairment in a prescription drug DUI case is the same observable impairment standard used in any other drug DUI: the government will rely on officer observations, field sobriety test performance, and any chemical test result.
If you have been charged with DUI in Georgia based on the alleged influence of a prescription medication, an attorney who understands the specific legal standards governing prescription drug DUI cases — including the incapable of driving safely standard and the available defenses — is essential to an effective defense.
