Minnesota CDL HazMat study guide
Minnesota CDL HazMat · Work through your exam, one topic at a time.
The Minnesota CDL Hazardous Materials (H) endorsement is a required addition to a Minnesota Commercial Driver's License for drivers who will operate vehicles carrying hazardous materials that require placarding, or who will haul certain quantities of hazardous materials in tanks or other configurations covered by federal hazardous materials rules. It is aimed at working and prospective commercial drivers in Minnesota - tanker drivers, LTL freight haulers, fuel and chemical delivery drivers, and linehaul operators - who need the endorsement added to an existing CDL or obtained alongside a new one. The knowledge test covers the hazardous materials portions of the CDL knowledge curriculum: identifying hazard classes and placards, shipping papers and emergency response information, loading and segregation rules, bulk and non-bulk packaging, marking and labeling, vehicle inspection and equipment, parking and routing rules, and emergency response procedures including the use of the Emergency Response Guidebook. Preparation should center on the hazardous materials chapters of the Minnesota CDL manual, repeated practice with placard-class and shipping-paper scenarios, and memorizing the specific numeric thresholds and parking rules that trip up candidates. Candidates should confirm current application procedures, testing locations, fees, and scheduling directly with Minnesota Driver and Vehicle Services, since program details change.

01Hazardous Materials Knowledge (H endorsement)
This domain tests the federal HazMat rules that a Minnesota CDL applicant must know to add the H endorsement: recognizing regulated shipments, reading shipping papers, using emergency response information, placarding, loading and parking limits, and emergency actions. A hazardous material is a substance DOT regulates in transport because it poses a risk. The shipping paper is the driver's main record. Its basic description must appear in order: UN identification number, proper shipping name, hazard class or division, and packing group when assigned.
