<human>: What are the best ways to get my son to stop using his cell phone when he is driving?
<bot>: The best way to get your son to stop using his cell phone while driving is to have an open and honest conversation with him. Explain why it's dangerous, and make sure that he understands how important it is for him to follow the rules of the road. You can also try setting up a reward system or taking away privileges if he continues to break the law. Additionally, you could consider installing a hands-free device in his car so that he doesn't have to hold the phone while driving.
