Many people believe that DUI charges only apply to alcohol or illegal drugs, but that is not true. In California, a driver can be arrested for driving under the influence if prescription medications or even over-the-counter medications affect their ability to drive safely. The law focuses on impairment, not on whether the substance was legal or prescribed.
Frances Prizzia helps you understand how prescription drugs can lead to DUI charges under California law. Our experienced California DUI lawyer defends people accused of DUI involving prescription drugs, whether caused by commonly prescribed drugs, sleep aids, or anti-anxiety medications.
Even if a medical professional legally prescribes your medicine, you can still face dui charges if the drug impairs your driving ability or mental alertness. Knowing your rights and how the law defines impairment is essential to protecting your future.
In California, driving under the influence (DUI) includes being impaired by alcohol, illegal substances, or legally prescribed drugs.
The focus is on whether your physical and mental abilities were sufficiently impaired to render you unsafe to drive a motor vehicle. Several laws define what counts as drug-impaired driving and what kind of evidence can be used in DUI cases.
Under California Vehicle Code § 23152(f), it is illegal to drive under the influence of drugs, including prescription medications. If a law enforcement officer believes a drug impairs your ability to drive, you can be charged with DUID, even if the substance was legally prescribed. The key issue is whether the driver’s system was so affected that the driver could not operate a vehicle safely.
According to California Vehicle Code § 23152(g), it is also illegal to drive under the combined influence of alcohol and other drugs. This includes cases in which both substances together render the driver unable to control a vehicle. Even if your blood alcohol content is below the legal limit, you can still face charges if drug impairment made you unsafe.
California law makes no difference between illegal drugs, illegal controlled substances, or legally prescribed medicines. What matters is whether the drug consumed caused impaired judgment, slowed reaction times, or poor decision-making behind the wheel.
Yes, prescription medications can absolutely lead to DUI charges. Even when you take only legally prescribed drugs, you can be accused of impaired driving if the medicine affects your coordination or alertness. Many commonly prescribed drugs can slow your reflexes, blur your vision, or make it difficult to focus while driving.
Under California law, impairment means that a person’s physical and cognitive impairment makes them unable to drive a motor vehicle safely. A person does not need to appear drunk; they simply need to show signs of reduced alertness, balance, or coordination caused by prescribed medication.
Many common prescription drugs can affect driving abilities. These include prescription painkillers, sleeping pills, muscle relaxants, anxiety medication, and flu medicine that causes drowsiness. Even medical marijuana can lead to DUI arrests if it reduces your alertness.
Even if your doctor legally prescribes the medication, you can still be arrested for a prescription drug DUI if the drug impairs your driving ability. The law looks at the effect on your body, not whether the drug was obtained legally.
In DUI cases involving prescription drugs, prosecutors must prove that your driving ability was affected by a substance. Police often rely on physical signs, chemical tests, and expert opinions to definitively prove impairment.
A blood test measures the amount of prescription medications or controlled substances in your system. These tests determine whether a drug consumed could cause physical and mental impairment. In many dui cases, prosecutors rely heavily on these test results to argue that a driver was under the influence of drugs while behind the wheel.
Your prescription medication records may be reviewed to see what medications you were taking, how often you took them, and whether they could affect your driving. Investigators may also contact your pharmacy or doctor to confirm that a medical professional legally prescribes the medication and to verify dosage details.
Police officers often use body cameras and dashcam footage to record a driver’s behavior. These videos help show how a driver appeared at the time, such as slurred speech, confusion, or unsteady movements. Footage can either help your defense or support the prosecution, depending on how the law enforcement officer conducted the stop.
A drug recognition expert (DRE) can testify in court to explain how certain commonly prescribed drugs or illegal street drugs affect the nervous system and impair a person’s ability to drive. Their testimony helps the court understand how legally prescribed drugs can impact a driver’s reaction times, coordination, and overall driving ability.
A prescription drug DUI is treated the same as any other driving under the influence charge. The penalties depend on the severity of the case and whether there are prior DUI convictions. The more serious the drug impairment, the harsher the sentence may be.
A first-time conviction may result in fines, probation, or up to 6 months in jail. More serious cases or subsequent offenses can result in up to four years in state prison.
A license suspension can occur from both the DMV and the court after a dui involving prescription drugs. Even without alcohol, the DMV may suspend your license for several months.
If convicted, you may need to complete a mandatory DUI school that teaches about the risks of drug-impaired driving.
If you have prior DUI convictions, you may face higher fines, longer jail sentences, and extended license suspensions. Penalties increase with each offense.

Police officers may conduct field sobriety tests, call a drug recognition expert, or order chemical tests, such as a blood test.
