When is it safe to use cell phones while driving?

Using hands-free devices while driving can enhance safety by allowing drivers to keep their hands on the wheel and their eyes on the road. This option recognizes the reality that many individuals need to communicate while driving, but emphasizes the importance of caution.

Hands-free devices, such as Bluetooth headsets or built-in car systems, reduce the physical distraction of holding a phone. However, it's essential to remember that cognitive distractions still occur when engaging in a conversation, even if hands-free. Therefore, while using these devices can be a safer alternative to handheld use, drivers should remain vigilant and aware of their surroundings.

The other options do not fully account for the complexities of modern driving situations. Using a cell phone only while parked or at red lights could potentially limit effective communication in urgent situations, while saying it's safe to use a phone whenever necessary disregards the distractions that come with any form of phone use while driving.
