In Ohio you need proof of insurance in order to drive. This is encapsulated in Ohio’s Financial Responsibility Law. As of March 23 drivers can now show their proof of car insurance with smartphones and tablets. I’m not sure how much of an advantage or benefit this is to the everyday driver. A car insurance policy in the form of a card or a printed piece of paper can simply be thrown into the glove compartment and forgotten. Having the information seems a bit redundant.
