That includes headsets, hands-free, whatever. Do not smugly assume you can keep using a phone because you do it hands-free. TURN OFF YOUR PHONES AND PAY ATTENTION TO THE ROAD, because otherwise this sort of nonsense happens:
You are NOT better than everyone else. Your conversations are NOT MORE IMPORTANT THAN SOMEONE ELSE'S SAFETY. You are NOT a better driver. You CANNOT "handle it just fine". It's NOT "okay this one time". It's NOT "only for a second".
If you are engaging with your phone in any way, you are AN ACCIDENT WAITING TO HAPPEN. Yes, some activities are worse than others (like this moron who was videotaping her kid in the back), but they are all increasing your risk of an accident.
Smarten up, especially those of you with kids. Does it terrify you that they'll one day be texting and driving? Then model better behaviour FFS! Are you sick of your teens being addicted to their phones? Then show that you're able to put yours down when required!
I am closing comments because I do not want to hear a bunch of entitled people explain why it's so important for them to put other people's lives at risk. Peo and I were in a Civic crushed between two SUVs because of someone who was on her phone. I have separately been rear-ended by someone on a phone. I don't want to hear why you're so much better than those people who thought they were driving safely as well.
If my father-in-law could pull over to take calls when he was an on-call pediatric hematologist working with very sick children, you can pull over to take your calls too.
