Exactly. Often it will have instructions NOT to contact the court, but to contact your local police.
The police cannot file the charge with the court until they can show proof of service. Your acknowledging receipt to a cop will do, so don't take the bait.
Really? That's an interesting bit of info. Having gotten 1 ticket in my entire life [for not having a current insurance card], I had no idea what the red light camera letters even said.
Thanks for the enlightenment!
