Answer
The driver can be legally charged with driving under the influence (DUI) because operating a motor vehicle while impaired by any substance, including over-the-counter medications, is illegal.
Under traffic safety laws, driving under the influence (DUI) applies to any substance—whether illicit, prescribed, or purchased over-the-counter—that impairs a person's physical or mental ability to drive safely. Drivers are responsible for reading package warning labels and avoiding driving if drowsiness or slowed reflexes occur.
