Why can using a cell phone while driving be dangerous?

Using a cell phone while driving can be dangerous for several reasons, all of which contribute to the overall risk associated with distracted driving. Firstly, handling a phone occupies one of the driver's hands, which takes away from their ability to control the vehicle. This physical distraction can hinder a driver's response time in critical situations, such as needing to steer or brake suddenly.

Additionally, using a cell phone creates a mental distraction. When a driver is engaged in a conversation or trying to compose a text, their cognitive resources are diverted away from the task of driving. This mental diversion makes it harder to focus on the road, recognize hazards, and make timely decisions, which can lead to accidents.

Moreover, there is a visual distraction involved when a driver looks at their phone screen. This visual attention away from the road can be particularly dangerous as drivers lose sight of vital information such as traffic signals, pedestrians, and other vehicles.

By integrating all these factors, it becomes clear that using a cell phone while driving poses multiple sources of danger, thus making the choice that encapsulates all these aspects the correct answer.
