Renew a CDL
The requirements for renewing your CDL are the same for renewing any other driver license with the exception of meeting the federal medical certification requirements. You will need to indicate compliance when you answer the required questions on the the MV-2CDL which is included with your renewal notice.
If you indicate the driving types NI (Non-excepted Interstate) or NA (Non-excepted Intrastate) on your renewal, you must provide a legible copy of your current USDOT Medical Examiner’s Certificate to DMV if it is not already on file. Please see Federal Requirements for Commercial Driver License (CDL) Applicants (MV-44.5) to help you determine your driving type.
