An F Endorsement Lets You Haul Hazardous Materials

An F endorsement on your commercial driver's license (CDL) means you are authorized to transport hazardous materials — things like gasoline, propane, explosives, poisons, and radioactive substances. Without this endorsement, you cannot legally carry hazmat loads, even if you hold a CDL for the vehicle class.

The F stands for hazmat (hazardous materials), and it is one of several endorsements available to CDL holders. If your job involves picking up or delivering hazmat cargo, your employer will require you to have this endorsement before you start that work.

Getting an F endorsement means passing a written test specific to hazmat rules, passing a background check, and in some cases undergoing a Transportation Security Administration (TSA) security threat assessment. The process takes longer than a standard CDL because the federal government screens hazmat drivers more closely.

Key Takeaways

  • An F endorsement authorizes you to transport hazardous materials in a commercial vehicle, and you cannot legally carry hazmat without it.
  • You must pass a hazmat knowledge test, a background check, and a TSA security threat assessment to receive an F endorsement.
  • The F endorsement appears on your CDL alongside any other endorsements you hold, and you renew it on the same schedule as your license.
  • Your state's Department of Motor Vehicles (DMV) or equivalent agency handles the process and testing process.

What You Need to Know Before You Test

Before you can take the hazmat knowledge test, you must already hold a valid CDL or have a CDL learner's permit. You cannot get an F endorsement on a regular driver's license. If you do not yet have a CDL, you will need to obtain one first through your state's standard CDL testing process.

You will also need to pass a background check. The TSA screens hazmat drivers for criminal history, immigration status, and other security factors. If you have certain felonies, outstanding warrants, or other disqualifying factors on your record, you may be denied the endorsement. Your state's DMV can tell you whether your background will likely pass before you pay for testing.

The hazmat knowledge test covers federal regulations about how to load, transport, and handle hazardous materials safely. You study from your state's CDL manual, which includes a hazmat section. Most people study for one to two weeks before taking the test. The test itself is usually 30 questions, and you must score at least 80 percent to pass.

The process and Testing Process

Start by visiting your state's DMV office or website to request a hazmat endorsement process. You will need to bring your current CDL, proof of identity, and proof of your Social Security number. Some states require you to fill out a TSA form (the HME form) as part of the process.

Once you submit your process and background check, the TSA typically completes its security threat assessment within 10 business days, though this can vary. If you pass, you will receive a letter or notification that you are cleared to test. If you are denied, you have the right to appeal the decision.

After you receive clearance, you schedule your hazmat knowledge test at your state's DMV testing location. You pay a fee (which varies by state, typically between $10 and $50) and take the written exam. If you pass, the F endorsement is added to your CDL when ready or within a few days, depending on your state's processing time.

How Long an F Endorsement Lasts

An F endorsement is valid for the same period as your CDL — usually four to eight years, depending on your state and your age. When your CDL expires, your F endorsement expires with it. You do not renew the endorsement separately.

If you renew your CDL before it expires, you can renew your F endorsement at the same time. Some states require you to pass the hazmat test again during renewal; others do not. Check with your state's DMV to learn the renewal rules where you live.

If your F endorsement is suspended or revoked — for example, because you violated hazmat transportation rules — you lose the right to haul hazmat when ready. You would need to reapply and pass all tests again to restore it.

Jobs That Require an F Endorsement

Common jobs that require an F endorsement include tanker truck driver, fuel delivery driver, and driver for a hazmat trucking company. Some construction companies, chemical manufacturers, and utility companies also hire drivers with F endorsements to transport materials to job sites.

If you work for a company that transports hazmat, your employer will tell you whether you need the endorsement before you are hired or shortly after. Many employers will not hire you for hazmat routes without proof that you already hold the endorsement, because training you and then having you fail the test costs them time and money.

Drivers with an F endorsement typically earn more than drivers without it, because hazmat work carries more responsibility and risk. The exact pay difference depends on your employer and location.

What Happens If You Drive Hazmat Without an F Endorsement

Driving a vehicle carrying hazardous materials without an F endorsement is a federal violation. You can be fined, your CDL can be suspended or revoked, and you may face criminal charges depending on the severity and the materials involved. Your employer can also be fined for allowing you to haul hazmat without proper authorization.

If you are stopped by law enforcement and found to be transporting hazmat without an F endorsement, the officer will likely issue a citation. Even a first offense can result in fines of several hundred dollars and points on your driving record.

Frequently Asked Questions

Can I get an F endorsement if I have a criminal record?

It depends on the type and age of the offense. The TSA screens all hazmat drivers and may deny the endorsement for certain felonies, drug convictions, or immigration violations. Contact your state's DMV to discuss your specific situation before you explore.

How much does it cost to get an F endorsement?

Costs vary by state but typically range from $10 to $50 for the knowledge test fee. Some states charge an additional process fee. Check your state's DMV website for the exact amount in your area.

Do I have to renew my F endorsement separately from my CDL?

No. Your F endorsement renews automatically when you renew your CDL. Some states require you to retake the hazmat test during renewal; others do not. Your state's DMV will tell you what is required.

How long does the TSA security check take?

The TSA typically completes the security threat assessment within 10 business days of receiving your process. In some cases it takes longer, especially if additional background information needs to be reviewed.

What if I fail the hazmat knowledge test?

You can retake the test. Most states allow you to test again after a waiting period of a few days to a week. You pay the test fee again each time you take it. There is usually no limit on how many times you can retake the test.
