The use of a **mobile phone** while driving is generally prohibited in Spain due to the risks of **distraction** it can cause. However, there is an exception: its use is allowed when a **hands-free device** is available. This device allows talking on the phone without needing to touch the screen, which reduces the risk of distraction by not having to hold the phone with your hands.

Despite this exception, it is important to note that even with a hands-free device, the driver can become distracted by paying attention to the conversation instead of the road. Therefore, it is recommended that conversations be brief and that the other person be informed that you are driving.

Additionally, it is crucial to remember that the use of **headphones** connected to the mobile phone is prohibited, except in specific cases such as on motorcycles and mopeds, where they can be used for GPS navigation functions. This is because headphones can isolate the driver from environmental sounds, increasing the risk of accidents.

In summary, the use of a mobile phone while driving is only permitted with a hands-free device, but caution should always be exercised to minimize distractions and ensure road safety.
