On a good note the DMV will provide a CDL with the HazMat endorsement that is valid for 90 days; but we cannot issue one until the background checks are completed and approved.
When will I be notified of the results of my background check?
The Federal Transportation and Security Admininstration or TSA will notify you by mail with the results of the background check.
How will I know if my application has been approved or disapproved?
