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 2.3, Poisonous Gas, is placarded with the "2.3" placard. What additional placard, if any, is required if the gross weight of the hazardous material is 8,000 pounds?
- A.A "POISON GAS" placard and a "2.3" placard.
- B.A "POISON" placard.(Correct)
- C.No additional placard is required.
- D.A "POISON GAS" placard.
Explanation
When the gross weight of a hazardous material is 8,000 pounds or more, the basic "2.3" placard is required. However, for Division 2.3, Poisonous Gas, an additional "POISON" placard must also be displayed, regardless of the gross weight, if the material is transported in bulk or in packages that require it. The "POISON GAS" placard is not a standard US DOT placard for this specific scenario.
- Question 2Placarding Requirements
You are hauling 9,000 pounds of UN1263, Paint, in non-bulk packaging. The shipping paper describes the material as "Paint, 3, UN1263, 9000 lbs." What placarding is required on the vehicle?
- A.The "CLASS 3" placard.(Correct)
- B.The "FLAMMABLE LIQUID" placard.
- C.No placarding is required as it's less than 1001 pounds.
- D.The "FLAMMABLE LIQUID" placard and the "CLASS 3" placard.
Explanation
For non-bulk shipments, placarding is generally required when the gross weight of the hazardous material is 1,001 pounds or more. For Class 3, Flammable Liquids, the "CLASS 3" placard is the correct placard to display when placarding is required. The "FLAMMABLE LIQUID" placard is not a standard US DOT placard.
- Question 3Placarding Requirements
A shipment contains 10,000 pounds of UN2810, Toxic Liquid, Organic, N.O.S., and 5,000 pounds of UN1993, Flammable Liquid, N.O.S. Both materials are in non-bulk packaging. What placarding is required on the vehicle?
- A.No placarding is required as the total is less than 1001 pounds for each material.
- B.Both the "POISON" and "FLAMMABLE LIQUID" placards.(Correct)
- C.Only the "FLAMMABLE LIQUID" placard for UN1993.
- D.Only the "POISON" placard for UN2810.
Explanation
For UN2810 (Toxic Liquid, Organic, N.O.S.), which is a Division 6.1 material, placarding is required because the gross weight (10,000 lbs) exceeds 1,000 lbs. The correct placard is "POISON" (or "TOXIC"). For UN1993 (Flammable Liquid, N.O.S.), which is a Class 3 material, placarding is also required because the gross weight (5,000 lbs) exceeds 1,000 lbs. The correct placard is "FLAMMABLE LIQUID" (or "CLASS 3"). Therefore, both placards are required.
