Sample Wyoming HazMat Test Questions

Question 1

A motor vehicle containing hazardous materials must not be parked within how many feet of an open fire?

  1. A 100 feet
  2. B 200 feet
  3. C 300 feet
  4. D 500 feet

Correct answer: C – 300 feet

Federal law prohibits parking a motor vehicle containing hazardous materials within 300 feet of an open fire. The Wyoming CDL manual also states this distance in its hazardous-materials parking rules. When driving near an open fire, the driver must first determine that the vehicle can pass safely without stopping.

Question 2

If hazardous materials are spilling from your disabled vehicle, what should you do?

  1. A Drive to the nearest repair facility
  2. B Leave the vehicle without reporting the spill
  3. C Unload the material onto the shoulder
  4. D Park, secure the area, remain there, and call or send for help

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

Wyoming’s CDL manual instructs drivers not to continue driving merely to look for assistance when hazardous materials are spilling. Park the vehicle, secure the area, remain at the scene, and call or send someone for help. Keep people away and upwind, warn them of the danger, and keep the shipping papers available for emergency responders.

Question 3

A hazardous material begins leaking from your vehicle. How far should you relocate the vehicle?

  1. A Always move it upwind
  2. B No farther than 100 feet
  3. C No farther than 500 feet
  4. D Only the minimum distance safety requires

Correct answer: D – Only the minimum distance safety requires

Wyoming's CDL manual says a vehicle leaking hazardous material should not be moved farther than safety requires. Moving off the roadway or away from a gathering place may be appropriate when it improves safety. Do not move the vehicle if doing so would endanger you or anyone else, and never continue driving merely to search for assistance.

Question 4

What is the primary purpose of the shipper's hazardous-materials packaging?

  1. A To identify every risk without labels
  2. B To contain the material safely
  3. C To make handling more convenient for the driver
  4. D To replace the shipping paper and placards

Correct answer: B – To contain the material safely

Packaging is intended to contain hazardous material and protect people and the environment from contact or release. The Wyoming manual calls these requirements containment rules. Hazard labels, shipping papers, emergency information, and placards perform the separate function of communicating the material's risks.

Question 5

  1. A Classes 1, 2, 4, and 7
  2. B Division 2.1 and Classes 3, 4, and 7
  3. C Class 1, Division 2.1, and Classes 3, 4, and 5
  4. D Classes 2, 3, 4, and 5

49 CFR prohibits smoking on or near a vehicle while Class 1 explosives, Division 2.1 flammable gas, Class 3 flammable liquids, Class 4 flammable solids, or Class 5 oxidizing materials are being loaded or unloaded. Fire must also be kept away, and people nearby must not smoke, light matches, or carry an open flame.

Question 6

Which statement correctly describes the securement of compressed-gas cylinders on a motor vehicle?

  1. A They must always be upright, even if unsecured
  2. B They may lie horizontally without restraints
  3. C A flat cargo floor eliminates the need for securement
  4. D They may be upright or horizontal but must be restrained, racked, or boxed to prevent movement

Correct answer: D – They may be upright or horizontal but must be restrained, racked, or boxed to prevent movement

49 CFR requires Class 2 gas cylinders to be securely restrained against shifting, overturning, or being ejected during normal transportation. They may be secured in an upright or horizontal position, loaded in suitable racks, or packed in boxes or crates. A flat floor by itself does not satisfy the securement requirement.
