Your best option is to renew them prior to the expiration date. If your certificate does expire, you must have a new medical examination and obtain a new medical certificate. You must then provide the State Driver Licensing Agency (SDLA) the new medical examiner’s certificate. You are also responsible for applying to FMCSA for a renewal of your variance per CFR§391.51(b)(8)

For a copy of the medical examiner’s certificate, see Medical Examination Report (MER) Form, MCSA-5875 located in CFR§391.43(f)

You can find contact information for your state’s driver licensing agency on the USA.gov website.
