The HazMat (H) endorsement adds a specialized qualification to your existing CDL — authorizing you to transport hazardous materials on any route requiring DOT placards across Texas and nationwide.
Smart CDL Academy offers HazMat endorsement training in the DFW Metroplex. From the written knowledge exam to TSA background check guidance, we provide preparation and guidance across the H endorsement process — and as an authorized TPST #0221 testing center, we conduct applicable CDL skills testing at our Irving facility for eligible applicants, subject to requirements and scheduling. The HazMat knowledge exam is administered by Texas DPS.
The HazMat (H) endorsement is a federal endorsement added to your existing commercial driver's license that authorizes you to transport hazardous materials as defined and regulated by the U.S. Department of Transportation (DOT) under 49 CFR. Any CDL vehicle carrying materials that require a HazMat placard under DOT regulations requires a driver with the H endorsement — if the load requires a placard, you require the endorsement.
The HazMat endorsement is available to both Class A and Class B CDL holders who are U.S. citizens or lawful permanent residents. Materials covered under the H endorsement include:
The HazMat endorsement is a specialized qualification in the transportation industry, relevant to the DFW energy and petrochemical market.
Looking for HazMat + Tanker combined? The Combination (X) CDL endorsement combines both HazMat and Tanker qualifications. If you plan to haul both hazardous materials and tank vehicle loads, the X endorsement is the credential that covers both.
The HazMat endorsement is regulated by the federal government — specifically the TSA (Transportation Security Administration) — because hazardous materials transport is considered a national security concern. This is the most important step in the process, and the most misunderstood.
You must apply through the TSA's HTAP (Hazardous Materials Endorsement Threat Assessment Program) — the federal program that processes all HazMat CDL applicants. The HTAP process includes:
Timeline: TSA processing typically takes 30 to 90 days — this is the longest and most variable part of the HazMat endorsement process. Plan accordingly and start your TSA application as early as possible.
Criminal history: Certain disqualifying offenses under federal law (49 CFR § 1572.103) can prevent TSA approval. If you have any concern about your background, contact our admissions team at 972-989-6450 for a confidential discussion before enrolling.
Citizenship: U.S. citizens and lawful permanent residents are eligible. Other immigration statuses have restricted pathways — contact us to discuss your situation.
The HazMat written knowledge exam tests your understanding of hazardous materials identification, placarding requirements, loading and unloading procedures, emergency response protocols, shipping paper documentation, and DOT regulations under 49 CFR.
No CDL skills test is required for the H endorsement alone. This is a common misconception — the HazMat endorsement requires only the written exam plus TSA clearance. Skills tests apply to endorsements like Passenger (P) and School Bus (S), not HazMat.
Smart CDL Academy's HazMat training program provides preparation on topics relevant to the Texas DPS HazMat knowledge exam. As an authorized TPST #0221 testing center, we conduct applicable CDL skills testing at our Irving facility for eligible applicants, subject to requirements and scheduling. The HazMat knowledge exam is administered by Texas DPS.
Upon completing both the TSA security threat assessment and passing the written knowledge exam, the H endorsement is added to your existing CDL at the Texas DPS office. Your CDL will display "H" among your active endorsements — immediately expanding your route eligibility to include any load requiring a HazMat placard.
Renewal: The HazMat endorsement in Texas renews on the same 5-year cycle as your CDL — including a renewed TSA security threat assessment each time. Both the written exam and background check must be completed again at renewal.
The DFW Metroplex and North Texas region is an active petrochemical and energy logistics corridor — HazMat-endorsed CDL drivers work on routes throughout the area. Chemical and fuel tanker routes originating from Gulf Coast refineries regularly transit the I-35E/I-35W freight corridor through the Dallas-Fort Worth area, and AllianceTexas logistics operations in North Fort Worth include multiple HazMat-route carriers.
Types of HazMat CDL employment in the DFW market include:
Carrier hiring needs for H-endorsed CDL holders vary by employer, role, route, location, experience and market conditions.
Compensation varies by employer, role, route, location, experience and market conditions. Contact employers directly for current information.

Already planning to add the Tanker (N) endorsement too? The Combination (X) CDL endorsement combines both HazMat and Tanker qualifications. If you want to haul both hazardous materials and tank vehicles, the X endorsement is the credential that covers both.
The HazMat (H) endorsement authorizes you to transport all DOT-classified hazardous materials that require a HazMat placard — including flammable liquids (gasoline, diesel, aviation fuel), flammable gases (LPG, propane), toxic substances, corrosive chemicals, explosive materials, and radioactive substances. If the load requires a placard under federal DOT regulations, the driver requires the H endorsement.
The TSA security threat assessment is a federal background check required for all HazMat endorsement applicants. It is administered through the TSA's HTAP (Hazardous Materials Endorsement Threat Assessment Program). The process includes submitting an application, providing fingerprints for biometric identity verification, and undergoing an FBI criminal history review, immigration status check, and terrorist watch list screening. TSA processing typically takes 30 to 90 days.
The TSA security threat assessment is the longest part of the process — typically 30 to 90 days. Once you receive TSA clearance, the written knowledge exam can be scheduled. Total timeline varies depending on TSA processing speed. Contact our admissions team at 972-989-6450 for current typical timelines at our campus.
Certain criminal offenses are federally disqualifying under 49 CFR. The TSA makes the final determination during the security threat assessment.

Yes. The HazMat (H) endorsement is available to both Class A and Class B CDL holders. Both license classes authorize you to pursue the H endorsement, provided you meet the TSA eligibility requirements — U.S. citizenship or lawful permanent resident status.
The H endorsement covers HazMat (hazardous materials) only. The X (Combination) endorsement combines both HazMat and Tanker qualifications into a single endorsement. If you plan to haul both hazardous materials and tank vehicle loads, the X endorsement is the credential that covers both.
No. The HazMat (H) endorsement alone requires only the written knowledge exam plus TSA security clearance. No additional CDL skills test is required for the H endorsement. This is a common misconception — the skills test applies to endorsements like Passenger (P) and School Bus (S), not HazMat.
