Testing locations depend on your state and the testing service it contracts with

Your tanker endorsement test is administered by your state's Department of Motor Vehicles (DMV) or equivalent agency — often called the Department of Transportation or Driver Services depending on where you live. The state does not run the test itself; instead, it contracts with third-party testing companies to deliver the written exam and, in some cases, the skills test. This means the locations available to you depend on which company your state uses and where that company has set up testing sites.

You cannot take the test anywhere you want. You must use an approved testing location in your state, and you must bring the documents your state requires. The test cannot be taken online — it must be done in person at a physical location where a proctor can watch you.

Key Takeaways

  • Your state's DMV website lists all approved tanker endorsement testing locations, usually searchable by county or city.
  • Most states contract with companies like Pearson VUE or PSI to run testing sites, and you often book your appointment online through their portal.
  • Testing locations vary widely — some states have dozens of sites, others have only a few, so you may need to travel to the nearest one.
  • You must bring a valid ID and proof of residency to the test, and arrive early; most sites will not let you test if you are late.
  • The written test is offered regularly at most locations, but skills tests (if your state requires one) may only be offered on certain days or at certain sites.

How to find testing sites in your state

Start by going to your state's DMV or transportation department website and searching for "tanker endorsement testing locations" or "CDL testing sites." Most states have a searchable map or list that shows you every approved location in your state, often organized by county. Some states let you filter by the type of test — written only, skills test, or both.

If your state's website is unclear, call your local DMV office directly. The staff can tell you which testing company handles tanker endorsements in your area and give you the phone number or website to book an appointment. Do not assume the location nearest you offers tanker testing; some DMV offices handle only standard driver's license tests.

Third-party testing companies and how to book

Most states use one of two major testing companies: Pearson VUE or PSI. Both run online appointment systems where you can see available dates and times, choose a location, and pay the test fee. Your state's DMV website will direct you to the correct company for your state.

When you book, you will need to enter your driver's license number, date of birth, and the endorsement you want to test for. The system will show you locations near your zip code and available appointment slots, usually several weeks out. You pay the test fee at booking — this is separate from any endorsement fee your state charges after you pass. Fees vary by state and testing company, typically ranging from $30 to $100 for the written test.

What to bring and when to arrive

Bring a valid government-issued photo ID — a driver's license, passport, or military ID. Some states also require proof of residency, such as a utility bill or lease with your name and current address. Check your state's DMV website or your test confirmation email to see what documents are required; arriving without them will result in cancellation and loss of your test fee.

Arrive at least 15 minutes before your scheduled test time. Most testing sites will not allow you to test if you arrive after your appointment time, even by a few minutes. Bring a pen if the site allows it, though many sites provide pens or use computer-based testing where you do not need one.

Differences between written and skills testing locations

The written test — the knowledge exam about tanker safety and regulations — is offered at most testing locations regularly, often multiple times per week. You can usually book this test weeks in advance.

The skills test, if your state requires one, is more limited. Some states do not require a skills test for tanker endorsements; others do. If your state does, the skills test may only be offered at certain locations and on certain days — sometimes only once or twice a month. You will need to pass the written test first, and then you can book the skills test. Ask your state's DMV which locations offer skills testing for tanker endorsements, because it is often fewer than the locations offering the written test.

What happens if no locations are near you

If you live in a rural area or a state with few testing sites, you may have to travel. Some drivers travel 50 miles or more to reach an approved location. Check whether your state allows testing in a neighbouring state if you live near a border — some states have reciprocal agreements, but most do not.

If travel is a genuine hardship, contact your state's DMV directly and ask whether they offer any exceptions or alternative arrangements. Some states will allow you to test at a different location than your home state if you have a valid reason, but this is rare and must be approved in advance.

Rescheduling or cancelling your test appointment

If you need to reschedule, log back into the testing company's website (Pearson VUE or PSI) using your confirmation number and change your appointment. Most companies allow you to reschedule for free if you do so at least 24 hours before your test time. If you cancel within 24 hours, you usually lose your test fee.

If the testing site cancels your appointment — for example, due to weather or a system outage — the testing company will contact you and let you reschedule at no extra cost.

Frequently Asked Questions

Can I take my tanker test at any DMV office?

No. Only approved testing locations can administer tanker endorsement tests. Not every DMV office offers this test. Your state's website lists which locations are approved, and you must test at one of those locations.

What if I fail the test?

You can retake the test, but you must wait a set number of days — usually three to seven days — before booking another appointment. You will pay the test fee again. Check your state's rules on how many times you can retake the test within a certain period.

Do I need to make an appointment or can I just walk in?

Most testing sites require an appointment booked in advance through the testing company's website. Walk-in testing is rare and usually not available for tanker endorsements. Book your appointment as soon as you are ready to test.

Is the test the same at every location in my state?

Yes. The written test content is the same regardless of which approved location you test at. The questions, passing score, and time limit are set by your state and do not change between locations.

Can someone else take the test for me or help me during the test?

No. You must take the test yourself, and no outside help is allowed. The proctor will watch you during the entire test. Cheating or attempting to cheat will result in when ready disqualification and may affect your driving record.
