The use of a **mobile phone while driving** is one of the main causes of distraction at the wheel. This distraction can lead the driver to **pay more attention to the conversation** than to the road, which affects their ability to calculate distances and see traffic signs. As a result, it is common for the vehicle to **leave the road** or invade the opposite lane.

Furthermore, when holding the phone with the hand or shoulder, it becomes difficult to handle the steering wheel, increasing the risk of losing control of the vehicle and going off the road. Although the use of hands-free devices is legal, it can also be dangerous, as the driver still dedicates part of their attention to the conversation instead of driving. For these reasons, **leaving the road** is the most frequent accident associated with mobile phone use while driving.
