About the Minnesota Hazmat Test
Topics Covered
- ✓Hazardous materials classification and shipping papers — Minnesota examiners ask about proper placarding for ethanol and gasoline loads, common on MN routes to terminals in Rosemount and Pine Bend.
- ✓Loading and unloading procedures — Winter conditions mean extra care with temperature-sensitive materials; you'll need to know how cold affects vapor pressure in tankers on I-94.
- ✓Security plans and threat assessment — The TSA background check is mandatory before testing, and examiners often ask about your security plan for overnight parking at rest areas like the one near Hinckley.

📘 Study Tips & State Info
Minnesota examiners focus on the security plan and the "chain of responsibility" for hazmat. They'll ask about what to do if you hit a patch of black ice on I-94 near St. Cloud and your placarded load shifts. Don't just memorize the ERG — practice flipping through it in your head. The examiners love scenario questions that start with "You're driving a tanker of diesel on MN-36 in December…"
Use the Minnesota CDL handbook, but also read the federal hazmat regulations (49 CFR parts 100-185). The state test pulls directly from those. Pay special attention to the section on loading and unloading — Minnesota has specific rules about securing tankers during winter to prevent valve freeze-ups. If you can explain why you'd use a heated loading rack in Bemidji in January, you're ready.
Take our practice tests multiple times. The real test has 30 questions, 80% to pass. But don't rush — many fail because they skim questions and miss the Minnesota-specific twist. For example, a question about "what to do if a package leaks" might include a detail about icy roads and your proximity to the Mississippi River. Think before you click.
Minnesota DVS (Driver and Vehicle Services) handles all CDL testing. You'll need to make an appointment at your local exam station — walk-ins are rarely accepted at busy locations like Arden Hills or St. Cloud. The written hazmat test costs $10. After passing, you'll pay an additional $86 for the endorsement itself when you get your CDL. Bring your TSA threat assessment certificate (HME letter) before you take the test — they won't let you start without it.
Testing locations include Arden Hills (Twin Cities), St. Cloud, Duluth, Mankato, Rochester, and several others. Hours vary, but most offer CDL testing Monday through Friday 8 AM to 4 PM. Some locations, like Arden Hills, have separate hazmat testing days — call ahead. You'll need to bring your CLP (Commercial Learner's Permit), a valid medical examiner's certificate, and proof of residency (two documents).
One unique Minnesota rule: if you fail the hazmat test, you can retake it the next business day, but only after paying another $10 fee. There's no limit on attempts, but your CLP expires after 180 days. Plan your study time wisely — don't burn through retakes. Also, if you plan to haul hazmat across the Canadian border (common near International Falls), the test covers additional border crossing requirements.
About the Minnesota Hazmat Test
The Minnesota Hazmat endorsement isn't optional if you plan to haul anything from diesel fuel to anhydrous ammonia. Our state's got a huge agricultural and mining industry, and that means a lot of hazmat moves on roads like I-94, US-53, and MN-36. The test is 30 questions, federal standard, but Minnesota examiners add their own flavor — they expect you to know how winter weather affects hazmat handling.
You'll need this endorsement if you drive any vehicle that requires placards under Part 172 of the federal regulations. That includes tankers, box trucks with chemicals, and even some flatbeds carrying lithium batteries. The Minnesota DVS (Driver and Vehicle Services) administers the test at all CDL testing locations, from Arden Hills to St. Cloud to Mankato.
Here's the thing: Minnesota's cold. Black ice on I-35 near Forest Lake. Snow squalls on I-94 west of St. Cloud. Your hazmat training has to cover what to do when a load of corrosive material gets jostled in a jackknife. The examiners watch for that understanding. They don't want textbook answers — they want you to think like someone who's actually driven a placarded truck through a Minnesota winter.
