Drivers no doubt recognize the dangers of driving after consuming alcohol, but consuming other, seemingly less threatening substances also can put drivers in danger, even during times of day when drivers would otherwise think the roads are as safe as possible. In its 2013-14 National Roadside Study of Alcohol and Drug Use, the NHTSA found that 10 percent of weekday, daytime drivers surveyed tested positive for prescription and/or over-the-counter drugs. Many people recognize that prescription drugs tend to be stronger than OTC drugs, and that recognition may naturally compel them to be extra cautious before driving after taking prescription meds. But the potential side effects of OTC drugs also merits caution on the part of drivers. It’s vital that drivers recognize certain facts about OTC and prescription drugs and keep them in mind before getting behind the wheel.
