Can you be charged with DUI for driving after taking a legal prescription drug?
The rule
DUI laws cover any drug that affects your driving, including prescription and over-the-counter medicines. The law treats them the same as illegal drugs.
California's DUI laws cover alcohol and any drug that affects your driving. The law makes no difference between illegal drugs and medicines from a doctor or pharmacy.
From the California Driver Handbook, section 9, page 72. This question is our own wording of that rule. The handbook and the DMV have the final word.
