When must you use a cell phone while driving?

Answer: D — Never

You must never use a cell phone while driving because it increases the risk of accidents and distracted driving. While it may seem necessary to use your phone in certain situations, such as reporting a traffic accident or handling an emergency, it is always safer to pull over and park in a safe location before using your cell phone. Engaging in phone conversations while driving can also lead to distraction and impaired driving, making it unsafe for both the driver and others on the road. Therefore, it is important to prioritize the safety of yourself and others and refrain from using a cell phone while driving at all times.
