Regarding NJ Law. If I suspend Auto Insurance on my car, do I have to surrender the plates to the MVC?

I have a car that I seldom use now, can I keep the plates on the car with no insurance policy. And if I need to use this car, reactivate my auto policy for those specific days. Is this legal? I know in some states it is and in some not.

If I do suspend insurance and I do have to surrender the plates, how long do I have till the MVC penalizes me?
