You must renew at a DMV office, but it will not be accepted as proof of identification to board a domestic flight after October first.
if I can no longer use my CDL as identification for flight purposes, what should I use if I do not have a passport?
It is recommended that you upgrade to an Enhanced or REAL ID when you renew.
Are REAL ID's available now?
Yes, you can get your Enhanced or REAL ID today.
What are the renewal fees for CDLs?
The fees for the photo document and the supplemental Metropolitan Commuter Transportation District are the basic fees.  There could possibly be additional fees.
How much additional would it cost me if I am combining with a motorcycle Class MJ?
A motorcycle Class MJ would add an additional $8 to the total of your fees.
Do I need to meet the federal medical certification requirements every time I renew my CDL?
If you are a US citizen or lawful permanent resident you will only need to provide the required proofs on the first, original, amendment, reciprocity or renewal application on or after June 18, 2015.  The proof will be retained on your driving record.
What topic will I find more information on if I go to the MyDMV website?
