Sample Mississippi HazMat Test Questions

Question 1

Before starting or continuing a trip, what should you do if a hazardous-materials package is leaking?

  1. A Carry the package away from the vehicle
  2. B Continue slowly to the carrier's terminal
  3. C Transfer the contents into another package yourself
  4. D Do not transport it; stop and obtain help

Correct answer: D – Do not transport it; stop and obtain help

Federal regulations prohibit accepting or transporting hazardous material that has not been properly prepared for transportation. A leaking package discovered in transit must be handled using the safest practical procedures. The CDL manual warns drivers not to transport leaking packages or move a vehicle containing one under ordinary conditions; stop operations and obtain qualified assistance.

Question 2

Which explosive divisions may not be parked on or within five feet of the traveled portion of a public road?

  1. A Division 1.1
  2. B Division 1.2
  3. C Division 1.3
  4. D All of the above

Correct answer: D – All of the above

Federal regulations prohibit parking a vehicle containing Division 1.1, 1.2, or 1.3 material on or within five feet of the traveled portion of a public street or highway. All three divisions listed are covered. The brief operational-necessity exception applicable to certain other hazardous materials does not create the same five-foot parking allowance for these explosives.

Question 3

Which description correctly defines a safe haven for a vehicle carrying explosives?

  1. A Any fenced property with a full-time security guard
  2. B Any property enclosed by an eight-foot fence
  3. C An area specifically approved in writing by government authorities for unattended explosive vehicles
  4. D Any property where the owner has given permission to park

Correct answer: C – An area specifically approved in writing by government authorities for unattended explosive vehicles

Federal regulations define a safe haven as an area specifically approved in writing by local, state, or federal governmental authorities for unattended vehicles containing Division 1.1, 1.2, or 1.3 materials. Fencing, guards, or an owner's consent alone do not satisfy that definition. A vehicle carrying these explosives generally must otherwise remain attended.

Question 4

What minimum fire-extinguisher rating is required in the power unit of a vehicle carrying enough hazardous material to require placards?

  1. A UL 8 A:B
  2. B UL 8 B:C
  3. C UL 10 A:B
  4. D UL 10 B:C

Correct answer: D – UL 10 B:C

Federal regulations require the power unit to carry a fire extinguisher with an Underwriters Laboratories rating of at least 10 B:C when the hazardous-material quantity requires placarding. The extinguisher must be fully charged, readily accessible, and securely mounted. A lower rating does not satisfy this requirement.

Source: Mississippi Commercial Driver’s License Manual — § 9.6.8, “10 B C Fire Extinguisher”, 49 CFR § 393.95(a) – Emergency equipment on all power units

Question 5

A placard may be displayed for hazardous material even when it is not required, provided the placarding complies with the rules and represents an actual hazard of the material. True or false?

  1. A True
  2. B False

Correct answer: A – True

Federal regulations permit placards to be displayed for hazardous material even when placarding is not otherwise required. The placard must represent a hazard of the material being transported and must comply with the applicable design and display requirements. A misleading placard or one displayed on nonhazardous cargo is not permitted.

Source: Mississippi Commercial Driver’s License Manual — § 9.3, “Communication Rules”, 49 CFR § 172.502(a)(1), (c) – Prohibited and permissive placarding

Question 6

When must each tire, including dual tires, be inspected on a placarded hazardous-materials vehicle?

  1. A At the start of the trip and every 100 miles
  2. B Every two hours or 100 miles
  3. C Every hour or 50 miles
  4. D At the beginning of each trip and each time the vehicle is parked

Correct answer: D – At the beginning of each trip and each time the vehicle is parked

Federal hazardous-materials driving rules require each tire to be examined at the beginning of every trip and whenever the vehicle is parked. The schedule applies to dual tires as well as single tires. A leaking or flat tire generally must not be driven on except to reach the nearest safe repair location.
