Driving Under the Influence of Drugs (DUID): What to Know

Driving Under the Influence of Drugs in California

Driving under the influence (DUI) isn’t limited to alcohol. In California, you can be charged with a DUI if drugs impair your ability to drive safely. This includes prescription drugs, over-the-counter medications, and illegal substances.

What Does It Mean to Be Under the Influence of Drugs?

The law defines driving under the influence of drugs (DUID) as operating a vehicle while impaired by drugs to the extent that you cannot drive with the caution of a sober person under similar circumstances.

Common Substances Leading to DUID Charges

  • Prescription Drugs: Medications like painkillers, sedatives, or antidepressants can impair judgment and reaction time.
  • Over-the-Counter Medications: Some cold medicines or antihistamines may cause drowsiness or slowed reflexes.
  • Illegal Drugs: Substances like marijuana, cocaine, or methamphetamines can impair coordination, perception, and decision-making.
  • Combination of Alcohol and Drugs: Even if your BAC is below 0.08%, mixing alcohol with drugs can amplify impairment and result in a DUI charge.

How Are DUIDs Proven?

Unlike alcohol-related DUIs, there is no per se limit (like the 0.08% BAC standard) for drugs. Prosecutors rely on:

  • The officer’s observations of your behavior
  • Field sobriety test results
  • Blood or urine tests
