The cost of a tanker endorsement ranges from $100 to $500 for the written test and skills exam, but the total expense depends on your state, the testing facility, and whether you need training first

A tanker endorsement (also called a hazmat tanker endorsement or Class A tanker endorsement) is an add-on to your commercial driver's license that lets you haul liquids, gases, or other materials in tank vehicles. The endorsement itself — the test and licensing fee — typically costs between $100 and $300 in most states. However, if you need classroom or behind-the-wheel training before you take the test, your total cost can reach $500 to $1,500 or more.

The variation exists because each state sets its own testing fees, and private training schools charge different rates. Some states bundle the tanker endorsement fee with your general CDL renewal, while others charge it separately. If your employer requires the endorsement or if you're switching from a different type of commercial driving, you may also need hazmat certification, which adds another $150 to $300.

Key Takeaways

  • The written test and skills exam for a tanker endorsement cost $100 to $300 in most states, with the exact amount set by your state's Department of Motor Vehicles.
  • If you need training before testing, budget an additional $300 to $1,200 for classroom instruction and behind-the-wheel practice with a certified instructor.
  • Hazmat certification, which is often required alongside a tanker endorsement, costs $150 to $300 and must be renewed every three years.
  • Some employers cover part or all of the endorsement cost as part of hiring or retention, so ask before paying out of pocket.

Breaking down the endorsement test fee by state

Your state's Department of Motor Vehicles sets the fee for the written knowledge test and the skills test (pre-trip inspection, basic control, and on-road driving). Most states charge between $100 and $200 for both tests combined. A few states charge separately — for example, one state might charge $50 for the written test and $75 for the skills exam, while another bundles them at $150.

To find your state's exact fee, contact your state's DMV or commercial driver's license office directly. Their website usually lists all endorsement fees, or you can call the CDL section and ask for the tanker endorsement cost. Some states allow you to pay online when you schedule your test; others require payment at the testing facility on the day of your exam.

If you fail either the written or skills portion, you typically pay the fee again to retake that test. Most states allow you to retake the written test within a few days, but the skills test may require a longer wait — sometimes 14 days or more — and you must schedule a new appointment with an examiner.

Training costs if you need instruction before testing

Not all drivers need formal training to pass the tanker endorsement test. If you already hold a CDL and have tanker experience, you may only need to study the written materials and practice the pre-trip inspection on your own. However, if you're new to tanker driving or your employer requires it, a training course is often the fastest path to passing.

Classroom-only training (usually one to three days) costs $300 to $600 and covers the written test material, hazmat regulations, and tank vehicle physics. Behind-the-wheel training with an instructor costs $500 to $1,200 for three to five days of practice and typically includes the classroom portion. Some schools offer combined packages that include both classroom and driving time for $800 to $1,500.

Training schools vary widely in quality and reputation. Look for schools accredited by the Professional Truck Driver Institute (PTDI) or endorsed by your state's DMV. Many trucking companies have partnerships with training providers and may offer discounted rates to their drivers or cover the cost entirely if you commit to working for them for a set period.

Hazmat certification and its separate cost

A hazmat certification is different from a tanker endorsement, though they often go together. Hazmat certification allows you to transport any hazardous materials (not just liquids in tanks). If your job involves hauling gasoline, propane, chemicals, or other regulated materials, your employer will require both the tanker endorsement and hazmat certification.

The hazmat written test costs $85 to $150 depending on your state, and you must pass a federal background check (which costs $0 to $100 depending on whether your state charges a separate fee). The background check includes fingerprinting and a records review; it typically takes one to two weeks. Hazmat certification is valid for three years, after which you must renew it by passing the test again.

Some states combine the hazmat fee with your CDL renewal fee, while others charge it separately. If you already hold hazmat certification and are adding a tanker endorsement, you do not need to renew hazmat unless it is expiring soon — but check with your employer, as some companies require both to be current on the same schedule.

What employers typically cover versus what you pay

Many trucking companies and fuel transport companies cover the tanker endorsement cost as part of hiring or as a condition of employment. Some cover only the test fee ($100 to $300), while others cover the full cost including training ($800 to $2,000). A few companies require you to pay upfront and then reimburse you after you pass the test or after you work for them for a set period (often 6 to 12 months).

Before you pay for training or testing out of pocket, contact the companies you want to work for and ask whether they cover the endorsement cost. If you're already employed and your company is asking you to get a tanker endorsement, ask in writing whether they will pay for it. Some states have laws requiring employers to cover certain licensing costs, so check your state's labor department website as well.

If you're paying on your own, look for training schools that offer payment plans or sliding-scale fees based on income. Some non-profit workforce development programs also offer free or low-cost CDL training, though availability varies by region and you may need to meet income requirements.

Timeline and scheduling considerations

The written test can usually be scheduled within a few days of contacting your state's DMV or a third-party testing center. The skills exam typically requires more advance notice — often two to four weeks — because examiners have limited availability. If you need training first, add one to five days for the course itself, plus time to study and practice before your test date.

Hazmat background checks add one to two weeks to the timeline. If you need both a tanker endorsement and hazmat certification, plan for at least three to four weeks total from the time you start the process to the time you receive both credentials. If you're in a hurry, some training schools offer intensive programs that compress the material into two to three days, but these cost more ($1,000 to $1,500) and require full-time attendance.

Schedule your skills test only after you feel confident in your abilities. Failing the test means paying the fee again and waiting for another appointment slot, which can delay your start date if an employer is waiting for your endorsement.

Renewal costs and how often you pay

A tanker endorsement is valid as long as your CDL is valid — typically four to eight years depending on your state. When you renew your CDL, you can renew the tanker endorsement at the same time for a fee that ranges from $50 to $150 in most states. You do not need to retake the skills test during renewal; you only pay the renewal fee and pass a new written test if your state requires it.

Hazmat certification, by contrast, must be renewed every three years. The renewal cost is similar to the initial certification ($85 to $150), and you must pass the written test again. If your tanker endorsement and hazmat certification expire at different times, you will need to renew them separately.

Some states offer discounts if you renew your CDL and hazmat certification together, so ask about bundled renewal fees when your credentials are approaching expiration.

Frequently Asked Questions

Can I get a tanker endorsement without taking a training course?

Yes, if you already hold a CDL and have tanker experience, you can study on your own and take the written and skills tests without formal training. However, most people find a training course helpful because tanker vehicles handle differently than other trucks, and the pre-trip inspection is detailed. Your state's DMV website has a study guide for the written test.

Does the tanker endorsement cost the same in every state?

No. Each state sets its own test fees, which range from $100 to $300 total. Some states charge separately for the written and skills portions, while others bundle them. Contact your state's DMV or commercial driver's license office to find the exact cost in your state.

What happens if I fail the tanker endorsement test?

You pay the test fee again to retake whichever portion you failed. The written test can usually be retaken within days, but the skills test may require a wait of two to four weeks for the next available examiner appointment. You do not need to retake training if you only failed the test.

Is hazmat certification required if I get a tanker endorsement?

Not always. A tanker endorsement alone lets you haul non-hazardous liquids in tanks. However, if you transport gasoline, propane, chemicals, or other regulated materials, your employer will require both the tanker endorsement and hazmat certification. Ask your employer which credentials you need before you pay for either one.

Can my employer make me pay for the tanker endorsement myself?

It depends on your state and your employment contract. Many employers cover the cost, but some require employees to pay upfront or share the cost. Ask your employer in writing before you pay. If they refuse to cover it and your state has laws about employer-paid licensing costs, contact your state's labor department for guidance.
