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.
