My fear about the hotline is that they are not federal agents. They are customer service reps. Don't know how good their word is. According to that link, I am surely following the law. But if agent checking reports me and I don't even know about it, it will be very difficult later.Thanks for sharing. This is new that not allowed to take U-Turn! Why did ask you to quarantine when you were leaving already any reason given?
You should be fine as you followed the guidelines from the agents you may mention the same, anyone else with experience do comment here.
