To be clear the new rules apply to not only making phone calls but also following maps, taking or making texts and engaging in social media while behind the wheel. You CAN still use a mobile phone if you are safely parked or to call 999 in an emergency when its unsafe or impractical to stop. Using 'hands free' is not illegal but if it distracts you and affects your ability to drive safely then you can still be prosecuted by the police. The advice being given today is to put your phone away when you get in the car and make your glovebox your phone box!
It's hoped that these new rules will prevent accidents caused by drivers being distracted by their mobile devices and so save lives.
