Sample Hawaii HazMat Test Questions

Question 1

A cargo tank is unloading Division 2.1 flammable gas, and its engine powers the transfer pump. If the hose lacks a discharge-end shutoff, when must the engine be stopped?

  1. A The timing depends entirely on the specific gas
  2. B After the filling or discharge connections are disconnected
  3. C When transfer ends, before the connections are disconnected
  4. D Either before or after disconnection is acceptable

Correct answer: C – When transfer ends, before the connections are disconnected

The engine may remain running when it is needed to operate the vehicle’s transfer pump. If the delivery hose does not have a shutoff valve at its discharge end, stop the engine when loading or unloading finishes and before disconnecting the filling or discharge connections. The running-engine exception applies only while the engine is needed for the transfer pump.

Question 2

A required hazardous-material label may be placed on a securely attached tag when the package is too small for the label.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

The statement is true. The Hawaii CDL Driver’s Manual notes that a hazard label may be placed on a securely attached tag when it will not fit on the package. The labeling rule permits this method for a nonradioactive package smaller than the required label, a cylinder, or a package with an irregular surface that cannot accept the label satisfactorily.

Question 3

For a hazardous-material shipment offered to a common carrier, who normally prepares the package, applies the required marks and labels, and certifies the shipping paper?

  1. A The motor carrier
  2. B The commercial driver
  3. C The shipper or offeror
  4. D The consignee

Correct answer: C – The shipper or offeror

The shipper or offeror is responsible for properly classifying and describing the material, selecting compliant packaging, and applying required marks and labels. The shipper also certifies the shipping paper, subject to limited regulatory exceptions. The Hawaii CDL manual instructs drivers to compare the shipping paper with the package markings and labels before accepting a shipment.

Question 4

Which type of package generally must be kept separate from food intended for people or animals unless an approved overpacking exception applies?

  1. A A package labeled FLAMMABLE LIQUID
  2. B A package labeled EXPLOSIVES 1.4
  3. C A package labeled POISON or POISON INHALATION HAZARD
  4. D A package labeled FLAMMABLE GAS

Correct answer: C – A package labeled POISON or POISON INHALATION HAZARD

Packages bearing POISON, POISON GAS, or POISON INHALATION HAZARD warnings generally may not be loaded with food, feed, or other edible material intended for human or animal consumption. Federal regulations provide limited exceptions for specified overpacking or separate closed loading arrangements. Drivers must confirm that any claimed exception satisfies the applicable packaging and loading requirements.

Question 5

What is the primary purpose of the Emergency Response Guidebook?

  1. A To teach commercial drivers how to operate tank vehicles
  2. B To guide initial response to hazardous-material incidents
  3. C To provide a complete list of CDL disqualifications
  4. D To designate approved hazardous-material routes

Correct answer: B – To guide initial response to hazardous-material incidents

The Emergency Response Guidebook provides initial safety information for firefighters, police, and other personnel responding to hazardous-material incidents. It is indexed by proper shipping name and identification number to help responders identify the material involved. The Hawaii CDL manual emphasizes giving responders the shipping papers and emergency-response information at an incident scene.

Question 6

What does “Forbidden” in Column 3 of the Hazardous Materials Table mean?

  1. A The material may travel only by highway
  2. B The load requires a POISON placard
  3. C The material may not be offered or accepted for transportation
  4. D The driver needs written permission from the carrier

Correct answer: C – The material may not be offered or accepted for transportation

Column 3 identifies a material’s hazard class or division or states that transportation is forbidden. A driver or carrier must not accept a material listed as forbidden for transportation. A placard, special endorsement, or different transportation mode does not override that designation unless a specific regulatory authorization applies.
