Approx. 8 months ago I let the insurance on my car lapse due to financial hardship. My registration expired a month later, as in Pennsylvania you need proof of insurance to renew the registration. I recently purchased insurance for the vehicle again; how do I renew the registration? I never received any letters from the PA DMV about turning in the plate, so I still have it. I didn't even know you had to turn them in until recently! Is this going to cause a problem?
