Understanding DUIs for Driving on Prescription Medication in Tucson

Arizona Revised Statutes (ARS) §28-1381 outlines the state’s DUI laws. These laws prohibit driving under the influence of alcohol, illegal drugs, or any medication—prescription or otherwise—if it impairs your ability to operate a vehicle safely. Even if you’re following your doctor’s instructions, you can still face a DUI for driving on prescription medication in Tucson if the medication affects your coordination, reaction time, or judgment.

Certain prescription drugs, such as opioids, benzodiazepines, and sleep aids, are known to impair driving abilities. For example, medications like oxycodone or alprazolam (Xanax) may cause drowsiness, slower reflexes, or dizziness, increasing the risk of an accident. In Tucson, law enforcement actively monitors for any signs of impairment, even if the substance involved is a legally prescribed medication.


Hypothetical Scenarios

Scenario 1: The Overprescribed Driver

Sarah, a Tucson resident, is recovering from knee surgery. Her doctor prescribed oxycodone to manage her pain, and she has been taking it as directed. On a sunny afternoon, Sarah takes her medication before driving to a follow-up appointment with her orthopedic surgeon. While merging onto a busy street, she becomes slightly disoriented and misjudges the distance to the vehicle in front of her, causing a minor rear-end collision.

When officers arrive at the scene, they observe that Sarah’s eyes appear glassy, and her speech is slightly slurred. She explains that she has a prescription for oxycodone and has been taking it as directed. However, under ARS §28-1381(A)(1), Arizona law prohibits driving if a person is impaired to the slightest degree by any substance, including prescription medications. Sarah is asked to perform field sobriety tests, which she struggles to complete, citing dizziness and fatigue as factors.

A subsequent blood test reveals therapeutic levels of oxycodone in Sarah’s system. Despite the legality of her prescription, the officer determines that her medication likely impaired her ability to drive safely. Sarah is charged with a DUI for driving on prescription medication in Tucson, leaving her to face potential penalties such as fines, a suspended license, and mandatory DUI education programs.

In Sarah’s case, her defense might focus on arguing that the therapeutic levels of oxycodone in her blood did not cause impairment. However, the prosecution could counter by emphasizing her inability to safely control her vehicle, referencing ARS §28-1381(A)(1). Legal representation, like that offered by Arizona DUI Pros, is essential for challenging the evidence and achieving the best possible outcome.

Scenario 2: The Cautious Yet Unlucky Driver

John, a Tucson school teacher, has been prescribed alprazolam (commonly known as Xanax) to manage his anxiety. He is well aware of the medication’s potential to cause drowsiness and usually avoids driving for several hours after taking it. One evening, John takes his medication as prescribed and, after waiting a couple of hours, decides to drive to a nearby store to pick up dinner for his family.

On his way back, a police officer notices that one of John’s taillights is out and pulls him over for the equipment violation. During the stop, the officer observes that John seems slightly lethargic and his responses to questions are slower than expected. Concerned that John may be impaired, the officer asks him to step out of the car and perform field sobriety tests. Although John does his best, he stumbles slightly during the walk-and-turn test, and the officer decides to administer a blood test.

The test results show therapeutic levels of alprazolam, but Arizona law under ARS §28-1381(A)(3) states that the presence of any drug, including prescription medications, can result in a DUI if the driver is impaired. Even though John’s medication was legally prescribed and taken at a therapeutic dose, the officer concludes that it affected his driving ability. John is charged with a DUI for driving on prescription medication in Tucson.

John’s case demonstrates the subjective nature of impairment evaluations. His defense could focus on showing that his slow responses were due to fatigue or anxiety, rather than impairment caused by alprazolam. Arizona DUI Pros would work to highlight potential flaws in the officer’s observations or the testing methods, ensuring that John’s rights under ARS §28-1381(A)(3) are upheld.
