If a long mobile phone conversation is held, lasting more than a minute and a half, no matter how much the hands-free device is used, the vehicle's driver will stop concentrating on driving and will pay more attention to the conversation. If this is the case, a significant portion of the road signs, among other hazards, will no longer be correctly perceived.
