Because he is innocent until proven guilty and has the right to seek representation.

The good reason to not bother fighting it is that he won't receive any points in PA for the ticket. The good reason to fight the ticket is that his auto insurance policy will not be happy to discover such an aggressive speeding ticket.

At the very least, I think it is worth going to court to seek a plea deal with the officer. No need to get a lawyer. Usually they are willing to knock the speeding ticket down a bracket. From what I can see NJ has a 1 - 15 over category, a 15 - 29 category, and a 30+ category. It looks like the officer wrote 94 in a 65 mainly to keep it below the 30+ speeding offense. There is a decent chance as a first time offender that the ticket can be plead down to 1 - 15 over which will look way better for insurance.
