1.2 Getting the HazMat Endorsement

How to Earn the HazMat Endorsement

Quick answer: Start with your state's current HME instructions. A covered first-time H applicant completes FMCSA-approved ELDT theory, passes the state H knowledge test at 80% or better, and receives a favorable TSA Security Threat Assessment. The state controls the sequence and issues the credential only after every applicable requirement is satisfied.

Step 1: Confirm the state process

The endorsement appears on a state-issued CDL, so the state licensing agency controls the application order, test locations, item count, time, state fees, retest rules, and displayed expiration. Some states direct applicants to TSA before the knowledge test; others use a different order. Do not rely on another state's checklist.

Step 2: Complete ELDT theory if covered

The federal ELDT rule took effect February 7, 2022. A covered driver obtaining H for the first time must:

• choose a provider listed on the FMCSA Training Provider Registry;
• complete the required HazMat theory curriculum;
• earn at least 80% on the provider's theory assessment; and
• have the provider report completion electronically.

HazMat ELDT has no federal behind-the-wheel component. The ELDT assessment also does not replace the state H knowledge test.

Eligibility can depend on when a prior CDL or endorsement was issued. Use FMCSA's current applicability guidance instead of assuming every lapsed or transferred credential follows the same path.

Step 3: Apply for the TSA threat assessment

TSA's HME process includes identity and immigration-document review, fingerprints, criminal-history checks, and security-database checks. The acceptable-status and document rules are more detailed than “citizen or green-card holder”; use TSA's current document list for your situation.

TSA's current enrollment help information lists:

• $85.25 for standard enrollment in TSA-agent states; and
• $41 for an eligible holder using the TWIC comparability option in a participating state.

A non-agent state or state licensing agency may collect different or additional fees. The TWIC option has its own eligibility and expiration consequences, so do not choose it only because the fee is lower.

TSA does not guarantee a universal 30–60 day completion window. Identity, immigration, criminal-record, or adjudication issues can extend review. Apply early and use the official status channel.

Step 4: Pass the state knowledge test

The state test must use the federal 80% minimum passing standard. Study the state's current HazMat manual chapter, especially:

• hazard classes and divisions;
• shipping papers, markings, labels, and placards;
• loading, segregation, securement, and attendance;
• parking, routing, railroad crossings, and smoking rules;
• emergency response information and ERG use;
• vehicle inspection and prohibited practices.

The exact item count and time limit are state-specific.

Step 5: Complete issuance

A passing knowledge-test result does not by itself authorize HazMat driving. The state also verifies applicable ELDT and needs a favorable TSA determination before it issues, renews, or transfers H or X.

The threat assessment may be valid for up to five years, but the state determines the endorsement expiration printed on the CDL. TSA requires a new application and fingerprints for a new or renewed assessment.

Appeals and waivers

If TSA identifies a potential disqualifier, follow the notice:

• an appeal disputes an error, such as mistaken identity or an inaccurate record;
• a waiver asks TSA to grant eligibility despite an accurately identified waivable disqualifier based on the circumstances and rehabilitation.

The availability of a waiver depends on the type of disqualifier. A DMV clerk or practice-test company cannot decide that process.
