Sample Louisiana HazMat Test Questions

Question 1

When loading or unloading Class 1 explosive packages, which action is prohibited?

  1. A Securing a covering with effective tie-downs
  2. B Handling packages with bale hooks or other metal tools
  3. C Separating explosives from cargo that could damage them
  4. D Checking the cargo area for sharp projections

Correct answer: B – Handling packages with bale hooks or other metal tools

The Louisiana manual warns against using hooks or other metal tools to handle explosives. Federal regulation specifically prohibits bale hooks and other metal tools when loading, unloading, or otherwise handling Class 1 materials. Packages generally must not be thrown, dropped, or rolled, although the regulation provides a rolling exception for barrels and kegs.

Question 2

A placarded vehicle carrying hazardous materials must not be parked within what distance of an open fire?

  1. A 10 feet
  2. B 50 feet
  3. C 100 feet
  4. D 300 feet

Correct answer: D – 300 feet

Federal regulation prohibits parking a motor vehicle containing hazardous materials within 300 feet of an open fire. The parking restriction is different from passing a fire: before operating near one, the driver must take precautions to determine that the vehicle can pass safely without stopping. The CDL manual gives the same 300-foot parking distance.

Question 3

Hazardous materials regulations are designed to promote safe transportation, contain the material, and do what else?

  1. A Calculate taxes on each shipment
  2. B Communicate the material's hazards
  3. C Assign enforcement duties to each state
  4. D Allow carriers to select their own classifications

Correct answer: B – Communicate the material's hazards

Hazard warning labels, placards, shipping papers, and emergency response information communicate a material's hazards to drivers, carriers, and emergency personnel. Packaging and handling requirements help contain the material, while driver and equipment rules promote safe transportation. The Louisiana manual presents these as the main purposes of hazardous materials regulation.

Question 4

Your vehicle already carries dry silver cyanide. You are offered battery acid that could generate hydrogen cyanide if mixed with the cyanide. What must you do?

  1. A Load the acid only if every carton remains upright
  2. B Place the acid above the silver cyanide
  3. C Separate the materials with a cargo cover
  4. D Do not load the materials in the same vehicle

Correct answer: D – Do not load the materials in the same vehicle

Federal hazardous materials rules prohibit storing, loading, or transporting cyanides with acids when mixing the materials would generate hydrogen cyanide. Battery acid and silver cyanide under the condition stated must not be loaded together. Upright loading, cargo covers, or positioning one product above the other does not satisfy this segregation requirement.

Source: Louisiana Commercial Driver License Manual — § 9.4, “Loading and Unloading,” Figure 9.9, “Do Not Load Table”, 49 CFR § 177.848(c) – Segregation of hazardous materials

Question 5

Which document should you review first to determine whether a shipment contains hazardous materials?

  1. A The vehicle registration
  2. B The shipping paper
  3. C The driver's duty-status record
  4. D The loading-dock inspection log

Correct answer: B – The shipping paper

A hazardous materials shipping paper identifies and describes regulated materials in the shipment. It includes the required shipping description and other information needed by the driver and emergency responders. Packages should not be opened merely to determine whether their contents are hazardous.

Source: Louisiana Commercial Driver License Manual — § 9.3.4, “The Shipping Paper”, 49 CFR § 172.202 – Description of hazardous material on shipping papers

Question 6

Which description best identifies a cargo tank?

  1. A Any removable tank placed on a vehicle for transportation
  2. B A container intended only for transporting explosives
  3. C Bulk packaging removed from the vehicle for every loading and unloading operation
  4. D A bulk tank for liquids or gases that forms part of a vehicle or is loaded and unloaded without removal

Correct answer: D – A bulk tank for liquids or gases that forms part of a vehicle or is loaded and unloaded without removal

A cargo tank is bulk packaging intended primarily to carry liquids or gases. It may be permanently attached to or form part of a motor vehicle; certain tanks also qualify when their size, construction, or attachment allows loading and unloading without removal. The Louisiana manual emphasizes that cargo tanks remain on the vehicle during those operations.
