When driving, using a hands-free mobile phone...

Correct answer

is permitted, but it should be understood that it may also cause distractions.

Using a mobile phone with a hands-free system, although legally permitted while driving, can be a source of distraction for the driver. Even if your hands are on the steering wheel and your eyes are on the road, holding a telephone conversation can significantly divert your mental attention from the task of driving. Studies have shown that when a driver engages in a telephone conversation, even using a hands-free device, their ability to perceive and react to traffic signs is noticeably reduced. Specifically, after one and a half minutes of talking on the phone, a driver may fail to notice a significant proportion of signs and their attention to driving may decrease by up to 40%. This also affects driving speed and increases reaction time in unexpected situations.
