Answer

The driver can be lawfully charged with driving under the influence because DUI laws apply to any substance that impairs safe driving ability, including over-the-counter medications.
Driving under the influence (DUI) laws strictly prohibit operating a motor vehicle while impaired by any substance. This includes legal over-the-counter drugs, such as antihistamines and cold remedies, whenever they degrade reaction time, alertness, or motor control.

Step-by-Step Solution

1
Identify the driver's condition and the nature of the substance consumed.
The driver took an over-the-counter antihistamine that caused drowsiness, leading to unsafe driving.
Traffic safety laws evaluate whether the driver's ability to operate a vehicle safely has been degraded.
2
Apply statutory driving under the influence (DUI) principles to over-the-counter drugs.
DUI statutes prohibit operating a vehicle while impaired by any drug, regardless of legal or over-the-counter availability.
The driver is legally obligated to refrain from driving if any medication produces physical or cognitive impairment.
