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 Thresholds
A driver is transporting a shipment of Division 4.1 flammable solids. The shipment is packaged in UN 1325, Flammable solid, organic, n.o.s., with a gross weight of 15,000 pounds. The shipping paper states 'Flammable solid, organic, n.o.s. (contains trimethylthioketone), 4.1, UN1325, PG II'. What is the maximum amount of this material, in pounds, that can be transported without requiring a placard on the vehicle, assuming no other hazardous materials are present?
- A.2,000 pounds
- B.500 pounds
- C.0 pounds
- D.1,000 pounds(Correct)
Explanation
For Division 4.1, the threshold for placarding is 1,000 pounds. Since the shipment is 15,000 pounds, it exceeds the 1,000-pound threshold and requires placarding.
- Question 2Incident Response for Infectious Substances
A motor carrier receives a shipment of Division 6.2 infectious substances. The shipping paper lists 'Infectious substance, affecting humans, Class 6.2, UN2814, PG I'. The driver notices that the package is leaking. What is the IMMEDIATE action the driver should take?

- C.Continue to the destination and report the leak upon arrival.
- D.Remove the leaking package from the vehicle and place it on the side of the road.
Explanation
For Division 6.2 (infectious substances), any leakage is a serious incident. The driver must immediately stop in a safe location, notify emergency services (like 911) and the shipper/consignee, and await further instructions. Cleanup should only be attempted if specifically instructed and with appropriate personal protective equipment.
- Question 3Mixed Load Placarding
A truck is carrying a load of UN 1993, Flammable liquid, n.o.s., Class 3, PG I, with a gross weight of 5,000 pounds. The shipping paper also lists UN 1075, Petroleum gases, liquefied, Class 2.1, PG I, with a net weight of 2,000 pounds. What placards are required on the vehicle?
- A.Flammable Liquid (Class 3) only
- B.No placards are required as the individual quantities are below placarding thresholds.
- C.Flammable Liquid (Class 3) and Flammable Gas (Class 2.1)(Correct)
- D.Flammable Gas (Class 2.1) only
Explanation
The placarding threshold for UN 1993 (Flammable liquid, n.o.s., PG I) is 1,000 pounds. With 5,000 pounds, the 'Flammable Liquid' placard is required. The threshold for UN 1075 (Petroleum gases, liquefied, PG I) is 1,000 pounds. With 2,000 pounds, the 'Flammable Gas' placard is also required. Therefore, both placards are needed.
