In which scenario is it legal to use a mobile phone while driving?

Using a mobile phone with a hands-free device is legal while driving because many jurisdictions recognize this as a safer alternative to holding the phone. Hands-free devices allow drivers to communicate without needing to physically hold their phones, which helps maintain attention on the road and reduces distractions. This measure promotes safety by enabling drivers to keep their hands on the wheel and their focus forward while still being able to communicate.

In contrast, using a mobile phone while stopped at a traffic light may still be considered illegal in some areas, as drivers could be tempted to engage in texting or other distractions instead of being alert to changes in traffic. Driving over 60 mph often implies higher speeds where distractions can have more severe consequences, so laws typically prohibit phone usage in such scenarios. Additionally, driving in a residential area may still involve potential distractions from phone use, as it requires attention to pedestrians, children, and other vehicles. Therefore, the use of a hands-free device is the most legally acceptable option while driving.
