In my case, the police officer lied and said I was holding the phone while driving the car, not while stopped.
The judge ignored my contest to this, arguing that the law doesn't distinguish moving or not. The fact that the PC lied didn't bother the judge either.
I proved with evidence I had a bluetooth device, I proved the phone was not in use, I even showed a picture of the car interior with manual transmission (it's not possible to text/talk and drive while shifting), after the PC statement and the judges response, I recognized what a kangaroo court it was.
It gets better, I got a $100 fine for failing to show insurance papers because I didn't find them within 30 seconds, I got a $140 fine for the phone charge, then $150 a year for three years from my insurance carrier.
$690 for doing the safe thing and pairing my phone for hands-free use, while stopped.
I agree that loud music and food while driving is a major crash risk and should be in laws, but society seems to think 3,000 killed a year and many more maimed for life is ok.
