Sample Kentucky HazMat Test Questions

Question 1

Which feature distinguishes a portable tank from a cargo tank?

  1. A A portable tank is loaded or unloaded while off the vehicle
  2. B A portable tank must remain on the vehicle during loading
  3. C A portable tank may carry only liquids
  4. D A portable tank is used only for corrosive materials

Correct answer: A – A portable tank is loaded or unloaded while off the vehicle

Kentucky’s CDL manual distinguishes the tanks by how they are handled. A portable tank is not permanently attached, and its product is loaded or unloaded while the tank is off the vehicle. The tank is then placed on a vehicle for transportation, while a cargo tank remains on its vehicle during loading and unloading.

Question 2

Which description best matches a cargo tank?

  1. A A small package carried inside the cab
  2. B A container used only for liquid cargo
  3. C A portable tank unloaded after removal from the vehicle
  4. D A bulk tank loaded and unloaded while it remains on the vehicle

Correct answer: D – A bulk tank loaded and unloaded while it remains on the vehicle

The CDL manual’s key operational distinction is that a cargo tank remains on the vehicle during loading and unloading. A portable tank, by contrast, is loaded or unloaded while it is off the vehicle and is later placed on the vehicle for transportation. Cargo tanks may transport different types of hazardous materials, including liquids and gases.

Question 3

What are the required shape and minimum side measurement of a standard hazardous materials placard?

  1. A An oval at least 9.84 inches long
  2. B A triangle with 9.84-inch sides
  3. C A rectangle at least 10.5 inches wide
  4. D A diamond at least 9.84 inches on each side

Correct answer: D – A diamond at least 9.84 inches on each side

Federal regulations specify that a standard placard is a diamond, also called a square-on-point. Each side must measure at least 250 millimeters, or 9.84 inches. Placards displayed on the front, rear, and sides of a vehicle communicate the hazard class of the material being transported.

Question 4

Hazardous material is spilling from your disabled vehicle. What should you do?

  1. A Continue to the nearest repair facility
  2. B Try to unload the material by yourself
  3. C Leave the vehicle and walk away without warning others
  4. D Park, secure the area, remain there, and call for help

Correct answer: D – Park, secure the area, remain there, and call for help

The Kentucky CDL manual directs drivers not to continue driving merely to find a telephone, truck stop, or other assistance when hazardous material is spilling. Park the vehicle, secure the area, stay there, and call or send someone for help. Keep people away and provide responders with available shipment and location information.

Question 5

Which hazard class uses transport index numbers to control how much may generally be carried together in one vehicle?

  1. A Class 2
  2. B Class 5
  3. C Class 7
  4. D Class 8

Correct answer: C – Class 7

Transport index numbers are used with certain Class 7 radioactive-material packages. Federal regulations generally limit the combined transport index in a transport vehicle to 50, determined by adding the numbers shown on the individual package and overpack labels. Specified exclusive-use shipments are excepted from that general limit.

Question 6

Which cargo tank shipment requires an approved gas mask to be carried on the vehicle?

  1. A Any flammable gas shipment
  2. B Any shipment of hazardous waste
  3. C Chlorine transported in a cargo tank motor vehicle
  4. D Every placarded hazardous materials shipment

Correct answer: C – Chlorine transported in a cargo tank motor vehicle

Federal regulations require a chlorine cargo tank motor vehicle to carry a gas mask approved for chlorine service. The vehicle must also carry an emergency kit for controlling leaks in fittings on the dome cover plate. These equipment requirements do not automatically apply to every flammable-gas, hazardous-waste, or placarded shipment.
