Which of the following is true about using smartphones while driving?

Using smartphones while driving can be a significant distraction, which is why there are specific laws governing their use. The correct answer indicates that it is permissible to use a smartphone if hands-free technology is employed. This means that drivers can utilize Bluetooth, speakerphone, or other hands-free devices that allow them to keep their hands on the wheel and their eyes on the road while making calls or using certain functions. This approach is designed to minimize distractions and promote safer driving practices.

The other choices reflect misunderstandings about the laws regarding smartphone use while driving. It is not completely legal at all times, as there are restrictions in place to prevent distracted driving. While it is true that using a smartphone is illegal under certain circumstances, it is not banned altogether; hence, the statement asserting that it is illegal to use a smartphone at all is inaccurate. Finally, indicating that smartphone use is only illegal during the night is misleading, as the laws apply at all times, regardless of the time of day.
