Is it necessary to hold on to old auto insurance bills?

I switched auto insurance companies recently and I was just wondering if there is any reason at all I should keep my old auto insurance bills from the old company. I'm the one who HATES clutter and I want to get rid of things I don't need anymore. Thanks.
Answer:
I recently changed to AAA. If no claim pending it is not necessary to keep the old bills. But keep policy number for a couple months for refernece if need be.
I now use the plastic shoe boxes to weed out things then go through boxes and thin more later. I label each one, such as bills paid, autos, bank, charge accounts, phone, utilties, TAX reciepts, house repairs, Working well for me so far.
