When is it illegal to use your phone while driving?

Using your phone while driving is illegal in most jurisdictions when you are not using hands-free technology because it distracts the driver and increases the risk of accidents. Many laws have been established to promote safe driving practices, emphasizing the importance of keeping both hands on the wheel and paying full attention to the road. The use of hands-free technology allows drivers to maintain focus while still being able to communicate, thus minimizing distractions.

In contrast, the other options do not accurately capture the comprehensive nature of phone usage laws. For instance, driving above the speed limit does not inherently determine the legality of phone usage. Similarly, traffic jams and construction zones may have specific regulations, but they do not encompass the broader legal restrictions related to phone usage while not utilizing hands-free devices. Therefore, the correct response highlights a critical aspect of safe driving laws aimed at reducing distractions and promoting road safety.
