Which of the following is considered a distracted driving behavior?

Using a handheld device while driving is considered a distracted driving behavior because it diverts the driver's attention from the task of driving. Engaging with a handheld device, whether it's texting, calling, or accessing apps, can significantly impair a driver's ability to focus on the road, monitor traffic conditions, and react promptly to any hazards. This form of distraction can lead to slower reaction times and a greater likelihood of accidents, making it one of the most dangerous distractions while driving.

In contrast, listening to the radio, talking to passengers, and adjusting mirrors typically do not require as much cognitive engagement or visual focus as using a handheld device. These activities generally allow drivers to maintain a higher level of attention to driving compared to the focused interaction required with a handheld device.
