Sample Idaho HazMat Test Questions

Question 1

Which three facts are needed when determining the placards required for a vehicle?

  1. A The carrier's insurance limits, cargo weight, and number of fire extinguishers
  2. B The number of fire extinguishers, shipment weight, and vehicle registration weight
  3. C The material's weight, destination, and weather forecast
  4. D The hazard class, amount shipped, and total weight of all hazardous-material classes aboard

Correct answer: D – The hazard class, amount shipped, and total weight of all hazardous-material classes aboard

Placarding requirements depend on the material's hazard class, the amount of that material being shipped, and the total weight of all hazardous-material classes on the vehicle. The Idaho manual uses these three facts to guide drivers through the placard tables. Fire-extinguisher specifications, insurance information, and weather do not determine the required placards.

Question 2

What does a “D” in Column 1 of the Hazardous Materials Table indicate?

  1. A The proper shipping name is intended only for international transportation
  2. B The proper shipping name is appropriate domestically but may be inappropriate internationally
  3. C The entry is a generic shipping name requiring a technical name
  4. D The material is regulated only when transported by vessel

Correct answer: B – The proper shipping name is appropriate domestically but may be inappropriate internationally

Under the federal Hazardous Materials Table, a “D” identifies a proper shipping name appropriate for domestic transportation. That name may be inappropriate under international transportation regulations. An alternate proper shipping name may be selected when domestic or international transportation is involved.

Question 3

Shipping orders, bills of lading, and manifests are examples of what?

  1. A Documents used only by the shipper
  2. B Driver qualification records
  3. C Optional cargo receipts
  4. D Shipping papers

Correct answer: D – Shipping papers

Shipping orders, bills of lading, and manifests can serve as shipping papers. A hazardous-material shipping paper contains information identifying and describing the regulated cargo. Drivers must recognize these document types because emergency responders may need to locate the hazardous-material information quickly.

Question 4

Who uses the hazardous materials regulations to determine a product's identification number, proper shipping name, hazard class, and packing group?

  1. A The Department of Transportation inspector
  2. B The carrier
  3. C The shipper
  4. D The driver

Correct answer: C – The shipper

The shipper uses the hazardous materials regulations to classify and describe the material, including its identification number, proper shipping name, hazard class, and packing group when applicable. The Idaho manual assigns these preparation duties to the shipper. The carrier and driver must still check the shipment and refuse improperly prepared or leaking packages.

Question 5

What is the primary purpose of hazardous-material packaging requirements?

  1. A To communicate the hazard without labels or shipping papers
  2. B To contain the material safely
  3. C To make cargo handling more convenient for the driver
  4. D All of the above

Correct answer: B – To contain the material safely

Hazardous-material packaging rules are intended to contain the material under conditions normally encountered during transportation. Packages must be designed, filled, maintained, and closed to prevent identifiable releases and preserve their effectiveness. Labels, markings, placards, and shipping papers perform the separate function of communicating the hazard.

Question 6

If both “A” and “W” symbols apply to an entry in Column 1 of the Hazardous Materials Table, what do they indicate?

  1. A The material is unrestricted during air or vessel transportation
  2. B The entry applies only to highway transportation
  3. C The entry applies only to rail transportation
  4. D The entry generally has mode-specific applicability to air or vessel transportation

Correct answer: D – The entry generally has mode-specific applicability to air or vessel transportation

Under federal rules, “A” denotes a material generally subject to the Hazardous Materials Regulations when offered or intended for aircraft transportation. “W” provides the corresponding rule for transportation by vessel. The stated mode limitations do not apply when the material is a hazardous substance or hazardous waste.
