Topic 6 · Alcohol, Drugs, and Driving (DUI Laws)
Is it a defense to a DUI charge to claim you didn’t know your medication would affect you?
- Only if you have a prescription
- No, you are responsible for what’s in your body — correct answer
- Yes, ignorance is a defense
Why
Not knowing is not a defence. You are responsible for reading the label and knowing how anything you take affects you. (Handbook, Section 9.)
