Can a simple case of rear-ending go to a second trail in traffic court?Why?

Question

Does the officer who gave the ticket have to be there?

If both an officer and a witness are there will they both speak?

What if neither a witness or a officer is present for the prosecution?

Answer 1

A simple case of rear-ending isn't normally a "criminal" offense unless there is some sort of criminal act involved with the accident.

Accidents are normally civil issues.

In this case it maybe an issue involving a judgement against the person responsible for hitting another where the plaintiff or defendant decided to challenge the courts initial conclusion.

A second "trial" is more likely an "appeal" to a first case before the court!
