What effects does a mobile phone conversation lasting more than a minute and a half have on driving?
Human factor: Physical factors
Explanation
Using a **mobile phone** while driving, even with a **hands-free device**, can be very dangerous. Although the device allows you to talk without touching the phone, the driver's attention is divided between the conversation and the road. This causes the driver to **stop perceiving an important part of the traffic signals**, which increases the risk of accidents.
- **Distraction**: When talking on the phone, the driver pays more attention to the conversation than to driving. This affects their ability to see signals and calculate distances correctly.
- **Recommendations**: It is advised not to have conversations lasting more than a minute, even with hands-free, to minimize the risk of distraction.
In summary, although the use of hands-free is legal, it remains a significant source of distraction that can lead to missing important signals on the road.
