Understanding How Prescription Drug Use Can Lead to DUI Charges

Prescription medications play a vital role in managing various health conditions. However, in Florida, even lawful use of prescription drugs can lead to a DUI (Driving Under the Influence) charge if those medications impair your ability to safely operate a vehicle. As a Florida DUI defense lawyer, I often hear from individuals who were surprised to find themselves facing charges when they believed they were following their doctor’s orders. It’s crucial to understand how Florida law applies to prescription drug DUIs, the legal issues involved, and the potential defenses available.


What Is a DUI Under Florida Law?

Under Florida Statute § 316.193, a person can be charged with DUI if they are driving or in physical control of a vehicle while:

  • Under the influence of alcoholic beverages, chemical substances, or controlled substances, to the extent their normal faculties are impaired.

This statute is broad and includes not only illegal drugs but also prescription and over-the-counter medications. Florida law does not distinguish between substances legally prescribed by a doctor and those obtained illicitly. If a medication impairs your ability to operate a vehicle, you can be charged with DUI.


Common Prescription Drugs That Can Impair Driving

Several types of prescription medications are known to affect a person’s cognitive or physical abilities, increasing the risk of impairment. These include:

  1. Opioids: Medications like oxycodone or hydrocodone can cause drowsiness, slow reaction times, and impair decision-making.
  2. Benzodiazepines: Drugs such as Xanax, Valium, or Ativan can lead to dizziness, slowed reflexes, and confusion.
  3. Stimulants: ADHD medications like Adderall or Ritalin can cause hyperactivity, erratic driving, or impaired concentration.
  4. Sleep Aids: Medications such as Ambien are notorious for causing “sleep-driving” episodes.
  5. Antihistamines: These are often overlooked but can cause drowsiness and slower reflexes.

How Prosecutors Prove Impairment in Prescription Drug DUI Cases

Unlike alcohol-related DUIs, there is no legal limit for prescription drugs in your system. Instead, prosecutors rely on several pieces of evidence to prove impairment:

  • Observations from the Arresting Officer: Slurred speech, erratic driving, or failing field sobriety tests may be used to show impairment.
  • Toxicology Reports: Blood or urine tests may reveal the presence of prescription drugs.
  • Expert Testimony: Medical professionals may be called to explain how the medication affects the body and could impair driving abilities.

Defenses to Prescription Drug DUI Charges

If you are charged with DUI involving prescription drugs, it’s important to understand that a charge is not a conviction. There are several defenses that can be used to fight the case:

  1. Lack of Impairment Evidence: The prosecution must prove that your ability to drive was impaired. Having prescription drugs in your system is not enough. We can challenge the arresting officer’s observations and argue that your faculties were not diminished.

  2. Unreliable Field Sobriety Tests: Field sobriety tests are subjective and may not accurately reflect impairment, especially in cases involving prescription drugs. Certain medical conditions or disabilities can also affect your performance on these tests.

  3. Improper Toxicology Testing: Blood and urine tests must be conducted according to strict protocols. If those procedures were not followed, the test results can be challenged.

  4. Valid Medical Use: While lawful prescription use does not excuse impaired driving, showing that you were taking the medication as directed by your doctor may help build your defense.

  5. Police Misconduct: If the officer lacked probable cause for the traffic stop or arrest, any evidence obtained may be inadmissible in court.


Potential Penalties for Prescription Drug DUIs

The penalties for a DUI involving prescription drugs are the same as those for alcohol-related DUIs in Florida. These penalties increase with subsequent convictions and may include:

  • First Offense: Fines of $500–$1,000, up to six months in jail, license suspension, and mandatory DUI school.
  • Second Offense: Fines of $1,000–$2,000, up to nine months in jail, longer license suspension, and ignition interlock device requirements.
  • Third Offense: Felony charges, fines of $2,000–$5,000, and up to five years in prison.

In addition to these penalties, a conviction can result in a permanent criminal record, increased insurance rates, and potential professional consequences.

Florida DUI Defense FAQs

How can I be charged with DUI if I have a prescription for my medication?
Having a prescription does not exempt you from DUI charges in Florida. If the medication impairs your ability to drive safely, you can still be arrested for DUI. The prosecution must prove that your normal faculties were impaired, not just that the medication was in your system.

Can I refuse a blood or urine test if I’m stopped for a prescription drug DUI?
Florida’s implied consent law requires drivers to submit to chemical testing if an officer has probable cause to suspect impairment. Refusing the test can result in an automatic license suspension and may be used as evidence against you in court.

What should I do if I’m pulled over and taking prescription medication?
Be polite and provide your driver’s license, registration, and proof of insurance. You are not required to answer questions about your medication without an attorney present. If arrested, contact a DUI lawyer immediately to protect your rights.

Are field sobriety tests reliable for prescription drug DUIs?
Field sobriety tests are often used to assess impairment, but they are not always reliable, especially for individuals with medical conditions or disabilities. Your attorney can challenge the validity of these tests in court.

Can a prescription drug DUI affect my professional license?
Yes, a DUI conviction can have professional consequences, especially in fields like healthcare or education. It’s important to work with an attorney who understands how to protect your career while defending your case.

How can a DUI lawyer help with my case?
A DUI lawyer will review the evidence, identify weaknesses in the prosecution’s case, and develop a defense strategy tailored to your situation. They will negotiate with prosecutors, challenge improper procedures, and represent you in court to seek the best possible outcome.
