Yes, it's been longer than that.
Okay. For future reference, an insurance lapse of less than 25 days will require you to pay a civil penalty of $200. In this case, you would get to keep your plates. If you choose to surrender your plates, the penalty would be a 25 day suspension of your registration.
one more thing, to report my plates, if they have been stolen, what is the procedure? How can I get a new license plate?
You will need to report that the plates have been stolen and surrender their registration. The DMV can then issue a new registration and plates.
