What happens when your hazmat endorsement expires
Your hazmat endorsement on your commercial driver's license (CDL) expires on the same date as your CDL itself. When that date passes, you can no longer legally transport hazardous materials — even if you have been doing it for years. Your employer may reassign you to non-hazmat routes, suspend your pay, or end your employment, depending on your contract and their needs.
Renewing your hazmat endorsement is not automatic. You must take specific steps with your state's Department of Motor Vehicles (DMV) or equivalent agency, pass a new background check, and pay a renewal fee. The process usually takes a few weeks, so you should start before your current endorsement expires.
Key Takeaways
- Your hazmat endorsement expires on the same date as your CDL and must be renewed separately — it does not renew automatically.
- You will need to pass a Transportation Security Administration (TSA) background check, which includes fingerprinting and a records review.
- You must pass the hazmat knowledge test again, which covers regulations, placarding, and safe handling of different material classes.
- Renewal fees vary by state but typically range from $25 to $100 for the endorsement itself, plus the cost of fingerprinting and the TSA background check.
- The entire process usually takes three to six weeks, so begin your renewal at least two months before your endorsement expires.
The TSA background check and fingerprinting requirement
Before you can renew your hazmat endorsement, you must pass a Transportation Security Administration (TSA) background check. This check looks at your criminal history, immigration status, and other factors the TSA uses to determine whether you pose a security risk when handling hazardous materials.
The background check includes fingerprinting. You will go to an approved fingerprinting location — often a local police station, sheriff's office, or a private fingerprinting service — and have your fingerprints taken digitally or on a card. The fingerprints are sent to the FBI and TSA for review. This step costs money (usually $15 to $50 depending on your state and location) and is separate from your DMV renewal fee.
The TSA will disqualify you if you have certain felony convictions, outstanding warrants, or immigration violations. If you have questions about your own history, contact your state's DMV hazmat program before you pay for fingerprinting — they can sometimes tell you whether a past issue will block your renewal.
Passing the hazmat knowledge test
You must pass the hazmat knowledge test again at your DMV. This is a written test, usually 30 questions, covering hazardous materials regulations, how to identify hazard classes, proper placarding and labeling, and safe loading and unloading procedures. You need a passing score (usually 80 percent or higher, but this varies by state) to renew your endorsement.
The test covers nine hazard classes: explosives, gases, flammable liquids, flammable solids, oxidizers, toxic substances, radioactive materials, corrosives, and miscellaneous hazardous materials. You should study the hazmat section of your state's CDL manual before you test. Many states offer the manual online for free, and some DMVs have practice tests available.
If you fail the test, you can usually retake it the same day or within a few days, depending on your state's rules. There is typically no extra fee for retakes, but you may have to wait a few hours or come back another day.
Steps to renew your hazmat endorsement
The order of steps matters because some must happen before others. Here is the typical sequence:
- Contact your state's DMV or the office that handles CDL renewals and ask for the hazmat renewal process. They will tell you whether you need to renew in person or whether some steps can be done by mail or online.
- Schedule an appointment for fingerprinting at an approved location. Do this early — some locations have long wait times.
- Go to your fingerprinting appointment and pay the fingerprinting fee. Keep your receipt and any confirmation number you receive.
- Study the hazmat section of your state's CDL manual while you wait for your background check to clear (usually one to three weeks).
- Once your background check clears, schedule an appointment at your DMV to take the hazmat knowledge test and complete your renewal paperwork.
- Bring your current CDL, proof of identity, proof of residency, and your fingerprinting confirmation to your DMV appointment.
- Take the hazmat test. If you pass, pay your renewal fee (typically $25 to $100, depending on your state) and your new endorsement will be issued.
Timeline and what to do if you are running out of time
The entire renewal process usually takes three to six weeks from start to finish, depending on how quickly the TSA processes your background check and how soon you can get a DMV appointment. Some states are faster; others slower. If your endorsement expires in less than two months, contact your DMV when ready to find out whether you can still renew before the expiration date.
If your hazmat endorsement expires before you finish renewing it, you cannot legally transport hazmat until the new endorsement is issued. You will need to tell your employer and may be reassigned to other work. Some employers will hold your job; others will not. Starting your renewal early protects you from this situation.
A few states allow you to renew your hazmat endorsement up to a certain number of days before it expires (for example, 90 days early). Check your state's rules so you know when you can begin the process.
Costs and what to expect to pay
Hazmat endorsement renewal involves several separate fees. Your state's DMV charges a renewal fee for the endorsement itself, which typically ranges from $25 to $100. Fingerprinting costs $15 to $50 depending on where you go. The TSA background check itself is free, but you pay for the fingerprinting service that collects your prints.
Some states bundle these costs into one payment; others charge them separately. Ask your DMV for a full breakdown of costs before you start so you know what to budget. If you fail the hazmat test and retake it, there is usually no additional fee, but confirm this with your DMV.
If you renew your entire CDL at the same time as your hazmat endorsement, you will pay both the CDL renewal fee and the hazmat endorsement fee. These are separate charges.
What disqualifies you from hazmat endorsement renewal
The TSA background check can result in disqualification. You will be denied a hazmat endorsement if you have been convicted of certain felonies (including crimes involving explosives, weapons, or terrorism), if you have outstanding warrants, if you are in the country illegally, or if you have certain immigration violations. You will also be denied if you have been committed to a mental institution or found not guilty by reason of insanity.
Other reasons for denial include a history of drug trafficking or drug possession convictions within a certain time frame, depending on your state. If you have any of these issues in your background, you will not pass the TSA check, and your renewal will be denied. Your state's DMV can tell you more about specific disqualifying factors before you pay for fingerprinting.
Frequently Asked Questions
Can I drive hazmat while my renewal is being processed?
No. Once your current hazmat endorsement expires, you cannot legally transport hazardous materials, even if your renewal process is pending. You must wait for your new endorsement to be issued. Tell your employer as soon as you start the renewal process so they can plan for your absence from hazmat routes.
What if I move to a different state before my endorsement expires?
You will need to renew your CDL in your new state, which includes renewing your hazmat endorsement. Each state has its own process and fees. Contact your new state's DMV to find out their specific requirements and timeline.
Do I have to retake the hazmat test if I renew my CDL early?
Yes. Even if you renew your CDL before it expires, your hazmat endorsement must be renewed separately and you must pass the hazmat test again. The endorsement and the CDL have the same expiration date, so they renew together.
What happens if I fail the background check?
If the TSA denies your background check, your state's DMV will notify you in writing and explain the reason. You have the right to appeal the decision through the TSA's appeals process. Contact your state's DMV for details on how to file an appeal.
Can I renew my hazmat endorsement online or by mail?
Most states require you to appear in person at the DMV to take the hazmat knowledge test and complete the renewal. However, some states may allow you to submit certain paperwork by mail or renew online. Check your state's DMV website or call them directly to find out what options are available in your state.
