The use of a **mobile phone while driving** increases the risk of accidents mainly because it causes **maneuverability problems**. This occurs when the driver holds the phone in their hand or on their shoulder, which makes it difficult to properly handle the steering wheel. Additionally, using the phone diverts attention from the road, which can lead to leaving the roadway or invading opposite lanes.

Although hands-free devices allow talking without touching the phone, they are still dangerous because the driver pays part of their attention to the conversation instead of fully concentrating on driving. Therefore, maneuverability is affected, increasing the risk of accidents.
