Technically, in New York, your proof of insurance is required in your vehicle at all times. And, for not maintaining your insurance coverage, they can punish a first time offender by revoking the driver's license for one year. But, if the officer did not ask for it and you were not involved in any accidents during this lapse, chances are you will be fine. You can also call New York's department of motor vehicles to make sure your driver's license status is fine. Also, you can follow this link to learn more about the New York State Insurance Department.
