If you fail the written test or background checks, the DMV will issue a CDL that does not have a HazMat endorsement.
And how will I know if my application has been approved or not?
We will send you an approval notice along with instructions to go to a DMV office to obtain a CDL backed by HazMat. Your new CDL will display the expiration date of your CDL and the expiration date of your HazMat endorsement.
