Using a hands-free device still imposes cognitive distraction.

• A. No cognitive distraction
• B. No distraction
• C. Still potential cognitive distraction
• D. Safer than manual distraction

Answer: (C)

The main idea being tested is that talking on a hands-free device still creates cognitive distraction while driving. Even though your hands are free and your eyes can stay on the road, your brain is processing the conversation, listening, interpreting questions, and formulating responses. That mental load competes with the cognitive tasks of driving—monitoring other vehicles, predicting hazards, and deciding what to do next. Because of this shared attention, your reaction time and situational awareness can be diminished, increasing risk. So the statement that there is still potential cognitive distraction best captures what actually happens when you use a hands-free device.

The other options imply there’s no cognitive distraction or no distraction at all, which ignores the mental effort involved in conversing or thinking while driving. The idea that it’s safer than manual distraction is true in terms of reducing hands-free or visual demands, but it doesn’t negate the cognitive load—the brain is still occupied—so it doesn’t address the core point about cognitive distraction.
