Would that be dismissed?

More than likely not. Check with the court to find the citation the officer entered with the court. You can resolve you issue there. If you're lucky, it MAY be dismissed. But don't count on it.

The only thing that would get a traffic violation dismissed is if the statements about the violation are wrong. If the office didn't get the license plate or car type wrong. Or the location was wrong. Leaving off or entering the wrong fine ain't going to do it.
