You have to admit though, that to expect every officer to be intimately familiar with the laws/rules and regulations of every one of the 50 states is a bit of a stretch. You also have to realize that most neighboring states (to California) require and utilize a sticker on the rear plate, and that inspection stickers stuck on the windshield is mostly an east coast standard.
No, a NJ should not be treated any differently than any other driver from any other state, but with the "front windshield sticker" being an anomaly out west, I don't see anything unreasonable with regards to the stop.
Officer saw your plate, did not see a sticker... Is it reasonable for him to pull you over to further investigate? Should any subsequent alleged violation discovered by the officer be deemed as invalid? I guess that's for the judge to decide!
No! Your mere "not guilty plea" and your exercising the option to hold the state to the burden of proving their case will not result in any additional fines or court costs.
No doubt... Add in the administrative correction fee of $25 (for each) and the fact that you would have to re-register your vehicle once you return to NJ...
Still, I would try the TBD to see where the judge will take it; at least, you might get a dismissal on the 12951 violation as Carl has suggested. So you might get a part of that $466 refunded.
Nope... Unfortunately not. You'll have to take your chances on that one!
Once you enter a plea of guilty, your fine amount is due and payable and subsequently your case is closed. While you can request that your case be re-opened under specific and limited circumstances, simply "changing your mind" is not a valid reason to expect that to happen.
