Using a mobile phone while driving can be very dangerous, even if you use a **hands-free device**. Although these devices allow you to talk without touching the phone, they still divert part of your attention from the road to the conversation. This increases the risk of accidents, as you may misjudge distances, miss important signs, or even veer off the road.

To minimize these risks, it is advisable **not to have conversations longer than one minute**. Longer conversations can increase distraction and, therefore, danger. Additionally, it is important to inform the person you are speaking with that you are driving, so they are also aware of the situation and can help keep the conversation brief.

In summary, although the use of hands-free devices is legal, it remains a source of distraction. Therefore, limiting call duration to one minute is an important safety measure to protect yourself and others on the road.
