Quizplus · Accepted Answer

Research suggests that the main effect of cell phone use on driving safety can be attributed to the cognitive task of talking on the phone, which uses up attention that should be focused on driving. While using "hands-free" units may reduce the negative effect of holding the phone while driving, it does not completely eliminate the cognitive distraction caused by talking on the phone.

Thus, option D is incorrect.
