What is Drugged Driving? Everything You Need to Know

Driving While Intoxicated (DWI) isn’t limited to alcohol in Texas. Many people are surprised to learn that prescription medications, over-the-counter drugs, and illicit substances can also lead to a DWI charge. This expanded definition of impaired driving reflects the growing concern over drugged driving and its impact on public safety.

What Is Drugged Driving?

Drugged driving occurs when a person operates a motor vehicle while impaired by any substance that affects their mental or physical abilities. In Texas, the legal definition of DWI includes driving under the influence of alcohol, prescription drugs, over-the-counter medications, or illegal substances, or any substance that impairs your ability to drive safely.

Common Substances Involved in Drugged Driving Cases

Prescription Medications

Even medications prescribed by a doctor can possibly lead to impairment and a DWI charge if they affect your normal mental or physical faculties. Common examples include:

• Opioid Pain Relievers: Drugs like hydrocodone or oxycodone can cause drowsiness or impaired judgment.
• Benzodiazepines: Medications such as Xanax or Valium can slow reaction times and impair motor skills.
• Sleep Aids: Drugs like Ambien may lead to dangerous behaviors like sleep-driving.

Over-the-Counter Medications

Some OTC medications can impair driving, especially when combined with alcohol. Examples include:

• Antihistamines: Found in allergy medications, they can cause drowsiness and delayed reactions.
• Cough Syrups: Products containing dextromethorphan or alcohol can impair motor functions.

Illicit Substances

Illegal drugs are a significant factor in many drugged driving cases. Common examples include:

• Marihuana: While legal in some states, it remains illegal federally and for recreational use in Texas. THC, the active compound, can impair coordination and reaction times.
• Cocaine and Methamphetamine: These stimulants can lead to reckless driving and aggressive behavior.
• Hallucinogens: Substances like LSD or psilocybin can impair perception and motor control.

How Is Drugged Driving Detected?

Unlike alcohol impairment, which can be measured with a breathalyzer or chemical blood test, detecting drug impairment is more complex. Officers rely on several tools and methods:

1. Field Sobriety Tests

Officers may use physical and cognitive tests, such as the Horizontal Gaze Nystagmus or Walk-and-Turn, to assess impairment. Learn more in Field Sobriety Tests Explained.

2. Drug Recognition Experts (DREs)

DREs are specially trained officers who can identify signs of drug impairment through a 12-step evaluation process, including:

• Pupil size and reaction to light.
• Pulse rate and muscle tone.
• Behavioral observations.

3. Chemical Testing

Blood and urine tests can detect the presence of drugs, but these methods have limitations:

• Blood Tests: Provide accurate detection of substances but require a warrant in most cases and there is no per se amount of a detected drug that equals intoxication. No ethical expert can say a person is intoxicated on a drug, but rather, is limited to stating whether behavior displayed is consistent or inconsistent with a particular drug class (such as a central nervous system depressant).
• Urine Tests: Detect past drug use but are less reliable for determining current impairment.

Legal Implications of Drugged Driving

The consequences of drugged driving in Texas are similar to those for alcohol-related DWI offenses. Penalties can include:

First Offense

• Fines up to $2,000.
• Jail time of 3 to 180 days.
• License suspension for up to 2 years.

Aggravating Factors

Penalties increase if there are aggravating factors, such as:

• Having a minor passenger.
• Causing an accident resulting in injury or death.

Repeat offenses can lead to felony charges with severe consequences. For a comparative analysis of penalties, see DWI Penalties in Different States (Comparative Overview).

Challenges in Defending Drugged Driving Cases

Lack of a Clear Legal Limit

Unlike alcohol, which has a defined legal limit of 0.08% BAC, there is no per se universal standard for drug impairment. This makes it easier to challenge the prosecution’s evidence.

Testing Limitations

Chemical tests for drugs are not always reliable. An experienced attorney can:

• Question the timing and method of the test.
• Highlight the potential for false positives or contamination.

Individual Tolerance Levels

Prescription medications affect individuals differently. An attorney can argue that therapeutic use did not impair driving ability.
