Question: how much does it cost to add hazmat endorsement?
Answer: The overall cost of getting a CDL Hazmat endorsement is about $100. The TSA screening costs $86.50, plus whatever fees the state charges you to take the test and update your CDL-A license. If you're driving 2,500 miles a week, you'll make that back in two to four weeks, depending on how much of a bump in pay you get.
