Here the proof of insurance if your getting tags is just signing the form saying you have it. You do have to produce a dated current card if stopped though. Even thats got a big loophole. You get insurance and they give you a card for the next year, then they cancel the check and drop the insurance. So in a stop, you can still produce a 'valid' proof of insurance.
Also your tags expire on your birthdate, and in a case like yours, they will charge you for just 6 months (1/2 off), or you can buy 1 1/2 years at a discount rate. I did that on the motorhome which I bought about 4 months before my birthday.
