What’s different in Minnesota

Most Hazardous Materials questions are the same federal material in every state. One question in the app is written for Minnesota alone, from the Minnesota Commercial Driver's Manual (PS30002-33), Part A and Part B.

A Minnesota question, answer shown

An 18-year-old drives a 3,000-gallon petroleum tank truck only within Minnesota. Is that permitted?

Yes, but only if the truck's GVWR stays at or below 26,000 pounds
Yes, a tank under 3,500 gallons hauling petroleum intrastate qualifies at 18(correct answer)
No, every placarded hazmat load requires a driver at least 21 years old
No, petroleum needs an X endorsement, which is never issued under age 21

Minnesota generally requires 21 for hazmat but lets drivers of motorized tank trucks under 3,500 gallons carrying petroleum intrastate, and employees of fertilizer or ag-chemical retailers delivering to farms, drive at 18 within the state.

2,205 pounds or more
Any amount at all

Table 2 materials need placards once the aggregate gross weight, including packaging, reaches 1,001 pounds. Table 1 materials must be placarded in any amount.
