text: One reason you should not use your phone while driving is texting. One day you can be driving your car and you will get a text message from someone. That person will look at their phone and pick it up and start texting back. They will be all into their phone and not paying attention to the road. He or she will be trying to text back and pay attention to their phone and the road at the same time. They can be driving and slam on the brakes and the car behind them can hit them from behind and that caused an accident all because that person was trying to text someone back. You should not text and drive at all. That is so dangerous if you drive looking at your phone. Its alot of things that can happen when you are using your phone while driving vehicle. If you want to be on the phone with somebody while driving car you should get some where you can stick your phone in and talk to that person. You can also get pulled over by the police when using your phone while driving.
