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 1
A driver is transporting a shipment of 500 pounds of Division 4.1 Flammable Solid, UN2926, 'Polyester resin (solid), temperature controlled,' in a non-bulk packaging. What is the minimum required placarding for this shipment on the exterior of the transport vehicle?
- A.The placard required is the "FLAMMABLE SOLID" placard (placard number 441).(Correct)
- B.No placarding is required as the quantity is below the 1,000-pound threshold for Division 4.1.
- C.The placard required is the "DANGEROUS WHEN WET" placard (placard number 423).
- D.The placard required is the "FLAMMABLE" placard (placard number 325).
Explanation
For Division 4.1 Flammable Solids, placarding is required when the gross weight of the material is 1,000 pounds or more. However, UN2926 is an exception; placarding is required for any quantity of UN2926 when transported in a non-bulk packaging. The correct placard for Division 4.1 is the "FLAMMABLE SOLID" placard (placard number 441).
- Question 2
You are hauling a load of 8,000 pounds of Division 5.1 Oxidizer, UN3100, 'Organic peroxide type D, solid.' Your transport vehicle is a cargo tank. What is the correct placarding for this shipment?
- A.No placarding is required as it is a cargo tank and not a bulk packaging.
- B.Only the "OXIDIZER" placard (placard number 500).
- C.Only the "ORGANIC PEROXIDE" placard (placard number 520).
- D.The "OXIDIZER" placard (placard number 500) and the "ORGANIC PEROXIDE" placard (placard number 520).(Correct)
Explanation
When transporting Division 5.1 Oxidizers in a cargo tank, both the "OXIDIZER" placard (placard number 500) and the "ORGANIC PEROXIDE" placard (placard number 520) are required. This is because the material falls under both hazard classes and requires specific identification for safety protocols.
- Question 3
A driver is transporting 2,000 pounds of Class 3 Flammable Liquid, UN1203, 'Gasoline,' in non-bulk packaging. The vehicle is a freight container. What placarding is required?
- A.No placarding is required as the quantity is below the 1,000-pound threshold for Class 3.
- B.The "FLAMMABLE" placard (placard number 325) and the "GASOLINE" placard (placard number 1203).
- C.The "FLAMMABLE" placard (placard number 325) and the "DANGEROUS" placard (placard number 900).
- D.The "FLAMMABLE" placard (placard number 325).(Correct)
Explanation
For Class 3 Flammable Liquids, placarding is required when the gross weight of the material is 1,000 pounds or more. Since the shipment is 2,000 pounds, placarding is required. The correct placard for Class 3 is the "FLAMMABLE" placard (placard number 325). The UN number is not placarded on the vehicle unless it is a bulk packaging or a cargo tank.
