Under what circumstance can you legally use a cellphone while driving?

Using a cellphone while driving is heavily regulated due to concerns about distracted driving and safety on the roads. The correct choice, which allows for legal cellphone use, is when utilizing a hands-free device. This option is designed to minimize distraction by allowing drivers to keep both hands on the steering wheel and their focus on the road ahead. Hands-free devices, such as Bluetooth headsets or car systems that connect to your phone, enable drivers to make calls, send messages, and perform other functions without needing to physically handle the phone.

In contrast, the other scenarios represent situations where cellphone use could lead to unsafe driving behavior or further distraction. For example, being stopped at a red light does not exempt drivers from the regulation, as it encourages looking at the phone rather than paying attention to the intersection. Similarly, using a phone during a traffic jam can still be distracting, as drivers may lose focus on their surroundings. In residential areas, the risk of pedestrian traffic and sudden stops increases, making cellphone use potentially hazardous as well. Therefore, the most responsible and legal method of using a cellphone while driving is through hands-free technology.
