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 1Explosives
A commercial motor vehicle (CMV) placarded for Division 1.1 explosives is involved in a minor accident. The driver is instructed by emergency responders to move the vehicle to a safe location off the roadway. What is the minimum safe distance the driver must maintain from the roadway and other occupied structures when parking the vehicle, according to typical hazmat regulations?
- A.50 feet
- B.500 feet(Correct)
- C.100 feet
- D.200 feet
Explanation
Vehicles transporting Division 1.1 explosives require a significant safety buffer. While specific distances can vary based on the exact explosive material and quantity, a general guideline for parking such vehicles away from the roadway and occupied structures is 500 feet to mitigate potential blast effects.
- Question 2Tunnel Restrictions
You are transporting a shipment of UN2922, CORROSIVE LIQUID, TOXIC, N.O.S. (contains Hydrochloric Acid and Sodium Cyanide). The shipment is in 5-gallon containers, and the total net quantity is 100 gallons. What is the minimum distance you must maintain from a tunnel entrance if the tunnel has a posted speed limit of 35 mph and is designated as a 'No-Truck' route?
- A.This shipment is prohibited in the tunnel.(Correct)
- B.300 feet
- C.500 feet
- D.100 feet
Explanation
UN2922, CORROSIVE LIQUID, TOXIC, N.O.S. requires specific placarding and segregation. Given the presence of toxic and corrosive properties, and the fact that the tunnel is designated as a 'No-Truck' route, this specific hazardous material shipment is likely prohibited from entering.
- Question 3Placarding
A driver is transporting a load of Division 2.1 Flammable Gases, specifically UN1950, AEROSOLS. The total gross weight of the shipment is 30,000 lbs. What is the minimum required placard for the vehicle?
- A.FLAMMABLE GAS 2.1(Correct)
- B.FLAMMABLE LIQUID 3
- C.POISON GAS 2.3
- D.No placard is required for this quantity and class.
Explanation
Division 2.1 Flammable Gases require the FLAMMABLE GAS placard. While UN1950 AEROSOLS may have subsidiary hazards, the primary hazard dictates the main placard. The gross weight threshold for placarding is typically 1,001 lbs or more for most hazardous materials, and this shipment clearly exceeds that.
