Federal regulations require that all commercial learner permit holders or driver license CDL must certify to the type of commercial driving they perform right now or expect to perform; and USDOT Medical Examiner's Certificate will be required for some types of driving and must be submitted before current certifications expires.

Yes, you must keep a current USDOT Medical Examiners Certificate on file with the DMV if you self-certify to a Non-Excepted Driving type NA or NI.
