In fact, at your first appearance, the officer isn't required nor is he likely to be there. You won't get it dismissed at that point.
At trial, if he doesn't appear he may still get a continuance.
He's got a year.
Traffic school avoids the point, you'll need to determine if that's advantageous to you. The first thing to do since lidar was used is to see if the speed trap law applies in this case (what road was it? do they have a current traffic survey?).
When you bought the car is largely immaterial. You should have been displaying the unexpired temporary registration in the window. Were you?
Anyhow, if you've got the regular tags/registration, you can get that dismissed as a correctable violation (costs $25 admin fee).
