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) is placarded for Division 4.1 (Flammable Solids) and Division 5.2 (Organic Peroxides). When transporting these materials together, what is the MOST restrictive placarding requirement that must be applied to the vehicle?
- A.Both placards (Division 4.1 and Division 5.2) must be displayed.
- B.Only the placard for Division 5.2 (Organic Peroxides) is required.(Correct)
- C.No specific placarding is required as these are different divisions.
- D.Only the placard for Division 4.1 (Flammable Solids) is required.
Explanation
When carrying hazardous materials from different hazard classes, if one of the materials is forbidden on the same vehicle as another, then the vehicle must be placarded for the material that is forbidden. Organic peroxides (Division 5.2) are generally forbidden on the same transport vehicle with flammable solids (Division 4.1). Therefore, the vehicle must be placarded for Division 5.2.
- Question 2Placarding Thresholds
You are hauling a shipment of UN2442, Vanadium Pentoxide, solid, with a gross weight of 10,000 pounds. What placard is required for this shipment?
- A.Division 4.3 (Dangerous When Wet) placard.
- B.Division 6.1 (Poisonous Material) placard.(Correct)
- C.Division 8 (Corrosive Material) placard.
- D.No placard is required because the gross weight is below the 1,000-pound threshold.
Explanation
UN2442, Vanadium Pentoxide, solid, is classified as a Division 6.1 (Poisonous Material). The threshold for placarding shipments of Division 6.1 materials is 1,000 pounds gross weight. Since the shipment is 10,000 pounds, placarding is required using the Division 6.1 placard.
- Question 3Placarding Thresholds
A shipment of 500 pounds of UN1075, Compressed gas, n.o.s., is loaded onto your CMV. This material falls under Division 2.2 (Non-Flammable, Non-Poisonous Gas). What is the placarding requirement for this specific quantity?
- A.Only the shipping papers need to indicate the presence of a hazardous material.
- B.No placarding is required as the quantity is below the 1,000-pound threshold.(Correct)
- C.The vehicle must be placarded with the 'Dangerous' placard.
- D.The vehicle must be placarded with the Division 2.2 placard.
Explanation
For most hazardous materials, including Division 2.2 gases, placarding is required when the gross weight of the material is 1,000 pounds or more. Since this shipment is 500 pounds, it is below the threshold, and no placarding is required.
