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 driver is transporting a shipment of 49 CFR Part 173.133 Class 3, Division 3.2 flammable liquids in 5-gallon containers. The total net quantity of the hazardous material is 100 gallons. The vehicle is placarded with the Class 3 placard. What is the minimum number of 8-inch square, black and white, Class 3 placards required on the exterior of the vehicle?
- A.Four placards, one on each side, front, and rear.
- B.Two placards, one on each side of the vehicle.(Correct)
- C.Three placards, one on each side and one on the rear.
- D.No placards are required as the total quantity is below the threshold for placarding.
Explanation
For Division 3.2 flammable liquids, placarding is required when the net quantity exceeds 100 gallons. Since the total quantity is exactly 100 gallons, placarding is not strictly required by the 100-gallon rule. However, if the shipment were 101 gallons, two placards would be required (one on each side). The question states 100 gallons, which is the threshold for requiring placards. Therefore, two placards (one on each side) are the minimum required if placarding is initiated.
- Question 2Placarding Requirements
A driver is hauling a load of ammonium nitrate, UN2859, which is a Division 5.1 oxidizer. The net weight of the material is 5,000 pounds. The vehicle is a straight truck. According to 49 CFR Part 172.504, what is the minimum placarding requirement for this vehicle?
- A.Two Class 5.1 placards, one on each side of the vehicle.(Correct)
- B.One Class 5.1 placard on the rear of the vehicle.
- C.No placards are required as the net weight is below the 1,000-pound threshold for oxidizers.
- D.Four Class 5.1 placards, one on each side, front, and rear.
Explanation
For Division 5.1 oxidizers, placarding is required when the net weight exceeds 1,000 pounds. Since the net weight is 5,000 pounds, placarding is mandatory. For non-bulk packages, two placards are required for the sides of the vehicle.
- Question 3Placarding Requirements
You are transporting a shipment of Class 8 Corrosives, UN1760, in non-bulk packaging. The total net quantity is 1,500 pounds. The vehicle is a tractor-trailer combination. What is the correct placarding for this shipment according to 49 CFR Part 172.504?
- A.No placards are required because the material is in non-bulk packaging.
- B.Four Class 8 placards, one on each side, front, and rear of the trailer.(Correct)
- C.Two Class 8 placards, one on each side of the trailer.
- D.One Class 8 placard on the rear of the trailer.
Explanation
For Class 8 Corrosives, placarding is required when the net quantity exceeds 1,000 pounds. Since the net weight is 1,500 pounds, placarding is mandatory. For a tractor-trailer, placards are typically placed on the trailer. Four placards are required: one on each side, one on the front, and one on the rear of the trailer.
