Florida CDL Hazmat Endorsement — What to Expect
In Florida, CDL licenses including the Hazmat (H) endorsement are administered by the Florida Department of Highway Safety and Motor Vehicles (DHSMV). The knowledge test is taken at driver license service centers or authorized third-party testing providers.
The Florida CDL Hazmat test has 30 questions and requires a minimum 80% passing score (24 correct). The exam is based on the same federal FMCSA regulations under 49 CFR that apply in all 50 states — meaning the VoltExam app covers every topic tested.
Florida CDL licenses renew on an 8-year cycle — longer than most states. At each renewal, you must pass the Hazmat knowledge test again and complete a new TSA Security Threat Assessment. The TSA background check takes 2–4 weeks, so plan ahead before your CDL expiration date.
If you fail the knowledge test, Florida allows retakes after 24 hours. The endorsement fee is approximately $10, paid to the DHSMV separately from the federal TSA background check fee of $86.50.

Florida CDL Hazmat — Frequently Asked Questions
How many questions is the Florida CDL hazmat knowledge test?
The Florida CDL Hazmat endorsement knowledge test has 30 questions. You need a minimum score of 80% — 24 out of 30 correct — to pass. The test is administered by the Florida Department of Highway Safety and Motor Vehicles (DHSMV) at driver license service centers across the state.
Where do I take the Florida CDL hazmat test?
The Florida CDL Hazmat knowledge test is administered at Florida DHSMV driver license service centers. Some third-party CDL testing providers are also authorized. You can schedule an appointment through the DHSMV website or by calling your local service center. Bring your current CDL and TSA Security Threat Assessment approval.
How much does the Florida CDL hazmat endorsement cost?
The Florida CDL Hazmat endorsement fee is approximately $10 for adding the H endorsement to your CDL. This fee is paid to the Florida DHSMV. You also pay separately for the TSA Security Threat Assessment background check ($86.50 federal fee paid at an enrollment center). Retake fees apply each time you retest if you fail.
Do I need a background check for the Florida hazmat CDL endorsement?
Yes. Federal law requires a TSA Security Threat Assessment (STA) for all CDL Hazmat endorsement holders. You must apply at an authorized TSA enrollment center — typically located at UPS Stores and dedicated enrollment providers. Processing takes 2–4 weeks. You may take the written knowledge test while the background check is pending, but the DHSMV will not add the H endorsement to your CDL until TSA clears you.
How long does the Florida hazmat endorsement last?
The Florida CDL Hazmat endorsement renews with your CDL license — every 8 years in Florida. At each renewal, you must pass the Hazmat knowledge test again and complete a new TSA Security Threat Assessment. Since the TSA background check takes 2–4 weeks to process, plan to apply well before your CDL expiration date.
