Sample CDL Hazmat Endorsement practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Placarding Requirements
A commercial motor vehicle (CMV) transporting a Division 4.1 flammable solid is placarded with the 'Flammable Solid' placard. If the shipment also contains 500 pounds of a Division 6.2 infectious substance, what additional placarding is required, if any, for the CMV?
- A.The CMV must also be placarded with the 'Infectious Substances' placard.(Correct)
- B.The CMV must be placarded with the 'Subsidiary Hazard' placard for Division 6.2.
- C.The CMV must be placarded with the 'Forbidden' placard due to the mixed hazardous materials.
- D.No additional placarding is required as the primary hazard is already placarded.
Explanation
Division 6.2, regardless of the quantity, requires a 'Biomedical Waste' or 'Infectious Substances' placard when transported.
- Question 2Placarding Requirements
You are transporting 1,000 pounds of UN1075, Gases, compressed, Division 2.1 (flammable gas), and 1,000 pounds of UN1950, Aerosols, Division 2.1 (flammable gas). What placarding is required for the CMV?
- A.The CMV must be placarded with the 'Flammable Gas' placard, and the 'Aerosols' placard is optional.
- B.The CMV must be placarded with the 'Flammable Gas' placard for both materials.(Correct)
- C.The CMV must be placarded with the 'Flammable Gas' placard.
- D.No placarding is required as the total weight of each hazardous material is below the 1,000-pound threshold for placarding.
Explanation
When transporting multiple hazardous materials of the same hazard class (Division 2.1 in this case), the total gross weight determines the placarding requirement. Since both UN1075 and UN1950 are Division 2.1, and the total is 2,000 pounds, the CMV must be placarded with the 'Flammable Gas' placard on all four sides.
- Question 3Placarding Requirements
A shipment of UN2814, Toxic liquid, organic, n.o.s., Division 6.1, has a gross weight of 800 pounds. What placarding is required for the CMV if it is the only hazardous material being transported?
- A.The CMV must be placarded with the 'Subsidiary Hazard' placard for Division 6.1.
- B.The CMV must be placarded with the 'Toxic' placard.
- C.No placarding is required as the quantity is below the 1,000-pound threshold.(Correct)
- D.The CMV must be placarded with the 'Forbidden' placard.
Explanation
For Division 6.1 liquids and solids, placarding is required when the gross weight is 1,000 pounds or more. Since this shipment is 800 pounds, no placarding is required for this specific material.
