text: Cell phone usage while driving is unsafe. #1 reason why it is unsafe is because you can lose your life. Just reaching for things while driving takes your main focus off of the road and put you in danger. When your distracted from the road anything can happen even if its just a second thats all it takes for everything to go bad. For instance the second you look down at your phone for that text message is the same secon a pedestrian can walk across the street or another vehicle can cross your path and just like that your life can be ruined or it can be over.
