One last question about renew a hazardous materials (HazMat) endorsement, how can I do this by phone?
Sorry but that's not possible
Is it possible to get a temporary HazMat endorsement before background checks are completed?
Sorry but no. We can't issue the HazMat endorsement until the background checks are completed and approved. We will provide a CDL with the HazMat endorsement that is valid for 90 days
