True or False: Talking on a cell phone while driving has no significant effect on reaction times.

Talking on a cell phone while driving is widely recognized to have a significant impact on a driver's reaction times. Engaging in a conversation can distract the driver from maintaining full attention on the road, which in turn affects their ability to respond quickly to sudden changes or hazards, such as pedestrians, traffic signals, or other vehicles. Research has shown that cognitive distractions, like those caused by phone conversations, can lead to slower decision-making and delayed responses, thereby increasing the risk of accidents.

This understanding is backed by numerous studies that indicate that even hands-free devices, while allowing for some mobility, do not eliminate distractions. The mental effort required to engage in conversation diverts cognitive resources away from driving tasks, leading to impaired judgment and slower reactions. Therefore, the assertion that talking on a cell phone while driving has no significant effect on reaction times is incorrect, making the correct answer to the question false.
