Advice please!

My husband was pulled over because the tags were expired on my car, but the big problem was that his license was suspended three months ago because he couldn't pay the dmv and court fines. He was laid off from his job and he just now started a job. The officer didn't arrest him but she wrote him a ticket and his court date is in January. This is only offense but can he still get jail time?? What can happen to him? I'm so scared for him. I know he shouldn't have been driving but we can't change that now. I need advice ladies! Please help! I'm so scared.
