When can you legally use a cell phone while driving?

Using a cell phone while driving is regulated to ensure driver safety and minimize distractions on the road. The correct choice states that you can legally use a cell phone at any time if it’s hands-free. This means that if you are utilizing a voice-activated system or a headset that allows you to keep both hands on the wheel and your eyes on the road, you are legally permitted to engage in phone conversations or utilize other phone features while driving.

Hands-free devices are designed to reduce the risk of distraction since they allow drivers to communicate without needing to hold the phone or look at it, thus maintaining focus on driving. This makes the use of hands-free technology a safer option compared to holding or manipulating a device during operation of a vehicle.

Other options highlight specific situations that either restrict phone use or create conditions that may not legally or safely apply. Being stationary might imply being parked safely off the road, and stopping at a red light does not generally grant permission to use a phone, as you are still in control of a moving vehicle. Emergency calls, while potentially allowed in urgent situations, do not encompass the broader scope of hands-free use, which is acceptable generally as long as it complies with safety laws.
