You will be charged with operating an unregistered vehicle and/or aggravated unlicensed operation.
Ok. I'll pay the charges.I have another question: I'm planning on leaving the state next month, what  are the steps I should take? I don't want to leave the state without notifying DMV
Well, you need to know that States communicate with each other, so if you leave the state without notifying DMV will be aware of that. Before leaving the state, make sure to resolve any unaswered tickets, suspensions or revocations. You also have to surrender your license(s) plate(s) to NYS when you get to the new state.
Ok. I suppose I have to get a new car insurance in the new state. What happens if by accident I let the insurance lapse?
