About the Minnesota Hazmat Test

Minnesota's trucking industry moves a lot of hazardous materials. You'll see hazmat loads on I-35, I-94, and highways near the Iron Range. Taconite mining and agriculture both require hazmat endorsements for fuel, explosives, and fertilizers.

Our winters can turn a simple spill into a major hazard. You need to know how cold affects different materials. Minnesota also has specific routing restrictions for certain hazmat in the Twin Cities metro.

This practice test covers all the key topics from the Minnesota CDL Hazmat manual. Each question matches the official DMV exam. You'll learn about placards, labels, shipping papers, and emergency response.

Take the test now and see where you stand. No sign-up required.

Topics Covered

✓Placarding and labeling – Minnesota DOT requires proper placards for all hazmat loads, especially on roads near schools and hospitals.

✓Shipping papers – Keep them accessible; Minnesota law says you must present them during roadside inspections.

✓Loading and unloading – Prevent leaks on icy roads; Minnesota’s cold can cause containers to contract and fail.

✓Emergency response guidebook – Know ERG numbers; Minnesota’s Hazmat teams rely on this information.

✓Security threats – Transporting hazmat through the Twin Cities requires extra awareness of potential incidents.

✓Tank vehicle operation – Common in Minnesota for fuel delivery to farms and gas stations; special rules apply.

Study Tips

Study the Minnesota CDL Hazardous Materials manual. The real test pulls questions from it. Focus on the sections about placarding and the ERG.

Take this practice test multiple times. Review each wrong answer. Pay special attention to substance lists – Minnesota has some unique ones like anhydrous ammonia for agriculture.

Schedule your endorsement test at any DVS location. You can take the written test without an appointment at most offices. Bring your CDL permit and pay the fee.

The fee for the Hazmat endorsement test is $10 plus the cost of your CDL permit. You'll need to pass a background check from TSA before you get the endorsement. Apply for that early.
