A car without insurance in California?

I'm going to spend a few months outside US, and while I'm traveling my car insurance will expire. I am going to let the insurance expire and renew it when I'm back. Can I get into a trouble for just owning a car with no insurance (obviously, the car will be in the garage and none will use it)? Am I supposed to file Affidavit of Non-Use with DMV in this situation? PS: Stickers won't expire, if this changes anything
