These experiments show that driving while on the phone can be very distracting and therefore dangerous. So now that this study has been done the public should know that if they get a phone call while driving they should not answer and if they call someone who answers the phone while driving they should end the conversation as soon as possible. This study can not only lead to safer roads but it can also save
