Question 1Hazardous materials regulations, definitions, and driver responsibilities

Under the North Carolina CDL hazardous materials endorsement rules, which drivers are required to hold an HM endorsement?

  1. Only drivers making interstate hazardous materials deliveries
  2. Any driver who operates a vehicle transporting hazardous materials requiring placards Correct answer.
  3. Only drivers operating tank vehicles with a capacity of 1,000 gallons or more
  4. Only drivers hauling explosives and radioactive materials

Explanation

Federal and North Carolina rules require an HM endorsement on the CDL of any driver operating a commercial motor vehicle that transports hazardous materials in quantities requiring placarding. The endorsement is tied to placarded quantities, not to vehicle type, cargo class, or whether the trip crosses state lines.

Question 2Hazardous materials regulations, definitions, and driver responsibilities

A driver is preparing to transport a placarded load. Which document must the driver keep within reach while operating the vehicle?

  1. The shipping paper and emergency response information Correct answer.
  2. The shipper's safety data sheets
  3. The bill of lading only
  4. The vehicle registration and insurance certificate only

Explanation

Hazardous materials regulations require shipping papers describing the hazmat to be carried and kept within reach of the driver, along with emergency response information for the material being transported. These documents allow responders to identify the hazard after a crash or spill.

Question 3Hazardous materials regulations, definitions, and driver responsibilities

What is the primary purpose of the placards displayed on a vehicle carrying hazardous materials?

  1. To show the vehicle has passed a hazmat inspection
  2. To identify the shipper responsible for the load
  3. To warn emergency responders and the public of the hazard class on board Correct answer.
  4. To certify that the driver holds a hazmat endorsement

Explanation

Placards communicate the hazard class of the material to emergency responders, other drivers, and the public, so they can take appropriate precautions. They are a warning system for the hazard, not a record of the shipper, driver, or inspection status.

Question 4Hazardous materials regulations, definitions, and driver responsibilities

Before loading hazardous materials, which action best reflects the driver's responsibility to verify the load matches its paperwork?

  1. Compare the placards and material markings against the shipping paper description Correct answer.
  2. Rely on the loader's verbal assurance that the load is correct
  3. Check only the total weight against the bill of lading
  4. Assume the paperwork is correct if the trailer seal is intact

Explanation

The driver shares responsibility for ensuring the shipment is properly described, placarded, and marked, so the placards and package markings should be checked against the shipping paper. Catching a mismatch before departure prevents an improperly documented or mislabeled hazmat load from moving.

Question 5Hazardous materials regulations, definitions, and driver responsibilities

A driver is offered a shipment of a material that requires placarding, but the shipper provides no emergency response information. What is the correct course of action?

  1. Accept the load and obtain the information by phone en route
  2. Accept the load and write the response information from memory
  3. Accept the load if the placards are already on the trailer
  4. Refuse to move the load until the required emergency response information is provided Correct answer.

Explanation

Emergency response information must accompany a hazardous materials shipment, and a driver should not transport a placarded load without it. Refusing the load until the shipper supplies proper documentation protects the driver and responders.

Question 6Hazardous materials regulations, definitions, and driver responsibilities

Which statement correctly describes the driver's duty when a hazardous materials package is leaking during unloading?

  1. Stop operations, keep people away, and notify the proper authorities Correct answer.
  2. Cover the leak with cargo and continue the route
  3. Continue unloading quickly to empty the trailer
  4. Rinse the leak into a floor drain and finish the delivery

Explanation

A leaking hazmat package is a release situation; work should stop, the area should be secured, and appropriate authorities and the shipper/employer notified. Continuing work or concealing the leak can spread contamination and increase danger.

Question 7Hazardous materials regulations, definitions, and driver responsibilities

A driver is involved in a collision that spills a placarded hazardous material on a North Carolina highway. What must the driver do first?

  1. Continue to the destination if the spill appears small
  2. Leave the scene to find a phone and call the shipper before anything else
  3. Take reasonable steps to protect the scene and notify emergency responders Correct answer.
  4. Move the spilled material off the roadway with the vehicle

Explanation

After a hazmat incident the driver must take reasonable steps to protect people and the scene, then notify emergency responders and report the incident as required. Fleeing, moving the material manually, or continuing the trip can worsen the hazard and violate reporting duties.

Question 8Hazardous materials regulations, definitions, and driver responsibilities

What is the meaning of the term "hazardous material" as used in the CDL regulations?

  1. Any cargo that weighs more than 10,000 pounds
  2. Only materials listed as flammable liquids
  3. Any material the shipper chooses to label as dangerous
  4. A substance or material capable of posing an unreasonable risk to health, safety, and property when transported Correct answer.

Explanation

Hazardous material is defined as a substance or material that the Secretary of Transportation determines is capable of posing an unreasonable risk to health, safety, and property when transported in commerce. The definition covers many hazard classes, not just flammables, and is not based on weight.

Question 9Hazardous materials regulations, definitions, and driver responsibilities

A driver holds a CDL with a hazmat endorsement. Which additional requirement applies to that driver under federal and North Carolina rules?

  1. A commercial pilot's license
  2. A separate state permit for each hazmat class carried
  3. An annual physical examination beyond the standard DOT exam
  4. A background check and TSA security threat assessment Correct answer.

Explanation

Obtaining or renewing an HM endorsement requires a TSA security threat assessment, which includes a criminal history and immigration status check. This is in addition to the standard CDL knowledge test and DOT medical requirements.

Question 10Hazardous materials regulations, definitions, and driver responsibilities

A driver is transporting a material requiring a "DANGER" or "WARNING" label on packages. What does the label on the package indicate?

  1. The delivery priority of the shipment
  2. The package has been inspected by the state highway patrol
  3. The name and address of the consignee
  4. The hazard class and specific hazard of the material inside Correct answer.

Explanation

Hazard labels on packages identify the hazard class and specific hazard (such as flammable liquid or corrosive) of the contents. They allow handlers and responders to recognize the risk before opening or approaching the package.

Question 11Hazardous materials regulations, definitions, and driver responsibilities

Which of the following best describes the driver's responsibility regarding the hazardous materials endorsement on the CDL?

  1. The endorsement is optional for any driver hauling placarded loads
  2. The endorsement must be on the CDL before the driver operates a placarded vehicle Correct answer.
  3. The endorsement applies only to tank vehicles
  4. The endorsement can be added verbally by the employer

Explanation

A driver may not operate a commercial motor vehicle carrying placarded hazardous materials unless the HM endorsement is already on the CDL. The endorsement is a legal prerequisite, not an optional or employer-granted status.

Question 12Hazardous materials regulations, definitions, and driver responsibilities

A driver must know the hazard class of a material before loading. Where on the shipping paper is the hazard class number typically shown?

  1. In the driver's logbook remarks section
  2. Immediately after the basic description of the hazardous material Correct answer.
  3. Only on the placard, not on the shipping paper
  4. In the consignee's billing address block

Explanation

The shipping paper basic description includes the proper shipping name, hazard class, and identification number, with the hazard class shown as part of that description. The driver uses this to confirm placarding and handling requirements.

Question 13Hazardous materials regulations, definitions, and driver responsibilities

A driver is hauling a placarded load and approaches a railroad crossing with a low-clearance underpass nearby. Which action is most consistent with hazmat driving rules?

  1. Speed up to clear the crossing before the train arrives
  2. Avoid routes that require backing or tight clearance where possible and never block the crossing Correct answer.
  3. Stop on the tracks to check the underpass clearance
  4. Use the crossing only if the placards are removed

Explanation

Hazmat drivers should plan routes that avoid unnecessary backing and low-clearance hazards, and they must never stop on railroad tracks. Blocking a crossing with a placarded load creates an extreme risk if a train approaches.

Question 14Hazardous materials regulations, definitions, and driver responsibilities

Which of these is a driver responsibility related to smoking and hazardous materials?

  1. Smoking is prohibited within 25 feet of a placarded vehicle during loading or unloading Correct answer.
  2. Smoking is allowed only in the sleeper berth
  3. Smoking is allowed if the windows are open
  4. Smoking is permitted if the material is nonflammable

Explanation

Smoking, carrying a lit cigarette, and other ignition sources are prohibited within 25 feet of a placarded vehicle during loading or unloading. The restriction applies regardless of whether the specific material is flammable.

Question 15Hazardous materials regulations, definitions, and driver responsibilities

A driver is asked to transport a package marked "Cargo Aircraft Only." What does this marking mean for a highway driver?

  1. The package is restricted to air cargo and should not be accepted for highway transport as offered Correct answer.
  2. The package may be carried only in a tank vehicle
  3. The package must be placed in the cab with the driver
  4. The package may be loaded on any truck without restriction

Explanation

"Cargo Aircraft Only" is an air-transport restriction indicating the package may not be carried aboard passenger aircraft and is not authorized for general highway movement under that marking. A highway driver should question the shipment rather than accept it as offered.

Question 16Hazardous materials regulations, definitions, and driver responsibilities

Which statement accurately reflects the difference between a placard and a label?

  1. Placards go on packages; labels go on vehicles
  2. Labels are required only for radioactive materials
  3. Placards and labels are interchangeable terms for the same marking
  4. Placards are placed on the vehicle to show the hazard class of the load, while labels are placed on packages Correct answer.

Explanation

Placards are the large warning signs placed on the exterior of the transport vehicle, while hazard labels are smaller markings applied to individual packages. Both communicate hazard class, but at different levels of the shipment.

Question 17Hazardous materials regulations, definitions, and driver responsibilities

A driver discovers that a placard on the trailer is missing for one of the hazard classes on the shipping paper. What is the appropriate action?

  1. Remove all other placards to match the missing one
  2. Note the discrepancy in the logbook and depart
  3. Obtain the correct placard and display it before moving the vehicle Correct answer.
  4. Depart and let the receiver add the placard later

Explanation

The vehicle must display placards for every hazard class requiring them before it moves. The driver should resolve the missing placard rather than depart with an improperly placarded load.

Question 18Hazardous materials regulations, definitions, and driver responsibilities

Which document provides the driver with the proper shipping name, hazard class, and identification number for a hazardous materials load?

  1. The shipping paper Correct answer.
  2. The vehicle inspection report
  3. The cargo seal manifest
  4. The CDL medical card

Explanation

The shipping paper carries the basic description: proper shipping name, hazard class, and identification number, along with quantity and packaging information. Responders and enforcement use it to identify the material.

Question 19Hazardous materials regulations, definitions, and driver responsibilities

A driver is hauling a placarded load and must park overnight. Which practice best reflects hazmat parking rules?

  1. Park under a bridge to protect the load from rain
  2. Park away from populated areas and sources of ignition, and attend the vehicle as required Correct answer.
  3. Park with the engine running to keep the load warm
  4. Park in a populated residential area for security

Explanation

Placarded vehicles should be parked away from populated areas and ignition sources, and the driver must attend the vehicle or use a secure location as the rules require. Parking in congested or enclosed areas increases the risk to the public.

Question 20Hazardous materials regulations, definitions, and driver responsibilities

Which of these best describes the driver's role in the hazardous materials communication system?

  1. The driver verifies that required shipping papers, markings, labels, and placards are present and consistent Correct answer.
  2. The driver may remove placards at night to reduce visibility
  3. The driver designs the package labels and placards
  4. The driver is responsible only for driving and not for documentation

Explanation

The driver is the last check before the vehicle moves, verifying that shipping papers, package markings, labels, and placards are present and consistent with the load. Placards must remain displayed during transport, including at night.

Question 21Hazardous materials regulations, definitions, and driver responsibilities

A driver is asked to sign for a hazardous materials shipment. What should the driver confirm before signing?

  1. That the shipper has paid all freight charges
  2. That the shipment description matches the packages and required placards are available Correct answer.
  3. That the receiver has a loading dock
  4. That the driver's logbook is completely filled out

Explanation

Signing for a hazmat shipment acknowledges receipt, so the driver should confirm the description matches the packages and that the required placards and markings are in place. Payment, dock availability, and logbook status are unrelated to hazmat acceptance.

Question 22Hazardous materials regulations, definitions, and driver responsibilities

Which statement about the hazardous materials endorsement knowledge test is correct?

  1. It is waived for drivers with five years of experience
  2. It must be passed in addition to the general CDL tests before the endorsement is issued Correct answer.
  3. It is required only for drivers over 65
  4. It replaces the general CDL knowledge test

Explanation

The HM endorsement requires passing a dedicated hazardous materials knowledge test in addition to the general CDL tests and the TSA security threat assessment. Experience and age do not waive the requirement.

Question 23Hazardous materials regulations, definitions, and driver responsibilities

A driver is transporting a placarded load and is stopped by an inspector. Which items is the inspector most likely to request?

  1. The driver's personal vehicle insurance
  2. The shipping papers and the driver's CDL with HM endorsement Correct answer.
  3. The receiver's warehouse layout
  4. The shipper's tax records

Explanation

Inspectors verify that the driver holds the HM endorsement and that shipping papers and placarding match the load. These are the core compliance documents for a placarded hazmat vehicle.

Question 24Hazardous materials regulations, definitions, and driver responsibilities

Which of the following is a correct statement about the emergency response information that must accompany a hazmat shipment?

  1. It must be immediately available for use at the scene of an incident Correct answer.
  2. It is required only for explosives
  3. It can be replaced by the driver's memory of the material
  4. It may be kept at the terminal and retrieved later

Explanation

Emergency response information must be immediately available to the driver and responders at the scene, typically carried with the shipping papers. It cannot be stored at the terminal or supplied from memory.

Question 25Hazardous materials regulations, definitions, and driver responsibilities

A driver has a hazmat endorsement but lets it lapse while continuing to haul placarded loads. What is the consequence?

  1. No consequence as long as the load is properly placarded
  2. The shipper assumes all liability for the lapse
  3. The driver is operating without the required endorsement and is subject to enforcement action Correct answer.
  4. The driver may continue for 90 days after expiration

Explanation

Operating a placarded vehicle without a current HM endorsement is a violation of CDL requirements and exposes the driver and carrier to enforcement action. Placarding the load correctly does not substitute for a valid endorsement.

Question 26Hazardous materials regulations, definitions, and driver responsibilities

Under the hazmat regulations, a driver is operating a vehicle that requires placards. Which of the following must the driver carry in the vehicle's documentation?

  1. A shipping paper describing the hazardous materials, plus emergency response information Correct answer.
  2. A copy of the placard order form from the carrier
  3. The manufacturer's safety data sheet for each package
  4. A bill of lading only when the load crosses a state line

Explanation

A driver of a vehicle carrying hazardous materials that require placarding must keep the shipping paper within reach and must also have emergency response information available for use at the scene of an incident. The shipping paper identifies the material, and the emergency response information tells responders and the driver what to do if a release occurs.

Question 27Hazardous materials regulations, definitions, and driver responsibilities

A driver is loading a hazardous materials shipment and finds that one package's hazard label is torn and unreadable. What is the driver's most appropriate action?

  1. Load the package only if the shipping paper shows the same hazard class
  2. Load the package and note the damage on the shipping paper
  3. Refuse to load the package until the label is replaced or the package is corrected Correct answer.
  4. Remove the damaged label and load the package unlabeled

Explanation

Labels are part of the hazard communication system, and a package with a missing or illegible label does not meet the marking requirements for shipment. The driver should not accept or load it until the shipper corrects the labeling, because responders and handlers rely on the label to identify the hazard.

Question 28Hazardous materials regulations, definitions, and driver responsibilities

A carrier's vehicle carries a quantity of a hazardous material that does not meet the placarding threshold for that hazard class. Which statement about placarding is correct?

  1. The vehicle must still display the placard because any hazmat requires placarding
  2. The vehicle may be placarded at the driver's discretion
  3. Placards are not required for that class, though other required markings and shipping papers still apply Correct answer.
  4. Placards are required only when the material is loaded at night

Explanation

Placarding is triggered by the placarding table thresholds, so a quantity below the threshold for a given hazard class does not require that placard. The shipment may still need package labels, shipping papers, and emergency response information, so the absence of a placard does not mean the load is unregulated.

Question 29Hazardous materials regulations, definitions, and driver responsibilities

A driver is reviewing a shipping paper and sees the entry for a hazardous material. Which element of that entry identifies the specific substance by its regulatory name?

  1. The emergency response telephone number
  2. The total quantity and unit of measure
  3. The shipper's certification statement
  4. The basic description's proper shipping name Correct answer.

Explanation

The basic description on a shipping paper includes the proper shipping name, hazard class, and identification number, and the proper shipping name is the regulatory name that identifies the specific material. Responders, inspectors, and the driver all use that name to look up the correct hazards and response guidance.

Question 30Hazardous materials regulations, definitions, and driver responsibilities

A driver picks up a load of a hazardous material and notices the shipping paper lists an identification number that does not match the number on the package markings. How should the driver treat this discrepancy?

  1. Accept the load because the package marking controls over the paper
  2. Accept the load and correct the number on the shipping paper at delivery
  3. Resolve the discrepancy with the shipper before accepting the shipment Correct answer.
  4. Accept the load if the hazard class on the paper appears correct

Explanation

The shipping paper description and the package markings must agree, because both feed the same hazard communication system used by carriers, inspectors, and emergency responders. A mismatch means the shipment's description is unreliable, so the driver should have it corrected by the shipper before taking responsibility for the load.

Question 31Shipping papers, emergency response information, and communication requirements

Under the hazardous materials regulations, which document must a driver of a placarded commercial motor vehicle carrying hazardous materials keep within reach while operating the vehicle?

  1. The bill of lading for nonhazardous return freight
  2. The carrier's insurance certificate
  3. The vehicle registration and annual inspection report
  4. The shipping paper containing the hazardous materials description Correct answer.

Explanation

The shipping paper must accompany each hazardous materials shipment and be kept within the driver's immediate reach while the vehicle is in operation, so it can be produced for inspection or used by emergency responders. Registration, insurance, and unrelated freight documents do not satisfy this requirement.

Question 32Shipping papers, emergency response information, and communication requirements

When a shipping paper covers both hazardous and nonhazardous materials, how must the hazardous materials entries be presented?

  1. They must be highlighted or otherwise distinguished from the nonhazardous entries Correct answer.
  2. They may be scattered anywhere in the document
  3. They must be printed on a separate page attached to the back
  4. They must be listed before any nonhazardous entries

Explanation

When hazardous and nonhazardous materials appear on the same shipping paper, the hazardous materials entries must be distinguishable, for example by highlighting, contrasting color, or another approved method. This lets responders find the hazardous entries quickly. Scattering or burying them among other entries defeats that purpose.

Question 33Shipping papers, emergency response information, and communication requirements

On a shipping paper, what does the basic description of a hazardous material consist of, in the required order?

  1. Hazard class, proper shipping name, packing group, and UN identification number
  2. Proper shipping name, packing group, UN identification number, and hazard class
  3. UN identification number, proper shipping name, hazard class or division, and packing group Correct answer.
  4. Packing group, hazard class, proper shipping name, and UN identification number

Explanation

The basic description sequence is the UN identification number, the proper shipping name, the hazard class or division, and the packing group, with the packing group placed after the class. Following the prescribed order lets responders and inspectors read the entry consistently. Any other arrangement is not the required sequence.

Question 34Shipping papers, emergency response information, and communication requirements

A shipping paper entry reads "UN1203, Gasoline, 3, PG II." What does the "3" represent in this entry?

  1. The hazard class of the material Correct answer.
  2. The number of packages in the shipment
  3. The placard quantity threshold
  4. The packing group assignment

Explanation

In the basic description the number immediately after the proper shipping name is the hazard class or division. For gasoline, class 3 identifies it as a flammable liquid. The identification number carries the UN prefix, and the packing group appears at the end.

Question 35Shipping papers, emergency response information, and communication requirements

What must the shipper include on the shipping paper to satisfy the emergency response information requirement?

  1. A phone number for the carrier's dispatch office only
  2. A statement that the driver is trained in hazmat response
  3. A 24-hour emergency response telephone number that is monitored at all times the material is in transportation Correct answer.
  4. The local fire department's nonemergency number

Explanation

Emergency response information must include a 24-hour emergency response telephone number that is monitored during the entire time the material is in transportation, including storage incidental to movement. The number must connect to someone who can provide response guidance. A dispatch line or nonemergency number does not meet the requirement.

Question 36Shipping papers, emergency response information, and communication requirements

Which of the following is acceptable as emergency response information on a shipping paper for a hazardous materials shipment?

  1. The driver's medical examiner's certificate number
  2. The applicable emergency response guidebook page for the material Correct answer.
  3. The carrier's safety rating from the FMCSA
  4. A written statement that the material is nonflammable

Explanation

Emergency response information may be provided by referencing the appropriate emergency response guidebook pages for the material, or by other approved means such as a guide or written instructions. The information must be immediately available for use in an incident. Documents unrelated to response do not qualify.

Question 37Shipping papers, emergency response information, and communication requirements

A driver is hauling a placarded load and stops for a required rest break. Where must the shipping paper be kept?

  1. Locked in the trailer with the cargo
  2. Mailed to the consignee in advance
  3. Left with the shipper at origin
  4. In the driver's possession or immediately accessible in the cab Correct answer.

Explanation

The shipping paper must remain within the driver's immediate reach or otherwise readily accessible whenever the vehicle is in operation, and it should stay with the driver during stops. Leaving it in the cargo area or with the shipper would make it unavailable to responders.

Question 38Shipping papers, emergency response information, and communication requirements

An emergency response telephone number listed on a shipping paper must be monitored during which period?

  1. Only until the shipment crosses a state line
  2. Only while the vehicle is actually moving
  3. The entire time the hazardous material is in transportation, including storage incidental to movement Correct answer.
  4. Only during normal business hours

Explanation

The required emergency response telephone number must be monitored at all times the hazardous material is in transportation, which includes storage incidental to movement such as a terminal layover. Business-hours-only or moving-only coverage leaves gaps when an incident could occur.

Question 39Shipping papers, emergency response information, and communication requirements

What does the letter "G" indicate when it appears in parentheses after the hazard class on a shipping paper entry, such as "Class 3 (G)"?

  1. The material is a hazardous substance in a reportable quantity Correct answer.
  2. The material is a gas under pressure
  3. The material is a hazardous waste
  4. The material is a marine pollutant

Explanation

The parenthetical G after the hazard class identifies the material as a hazardous substance that is present in a reportable quantity. Other parenthetical notations identify different special categories. Recognizing these notations helps responders and inspectors see special handling concerns at a glance.

Question 40Shipping papers, emergency response information, and communication requirements

A shipper offers a hazardous material in a reportable quantity. What additional information must appear on the shipping paper beyond the basic description?

  1. The estimated delivery date
  2. The driver's home terminal address
  3. The name of the manufacturer's plant manager
  4. The words "RQ" and the name of the hazardous substance Correct answer.

Explanation

When a hazardous substance is shipped in a reportable quantity, the shipping paper must include the letters RQ and the name of the substance in addition to the basic description. This alerts responders to reportable release concerns. Manufacturer personnel, terminal addresses, and delivery dates are not part of that requirement.

Question 41Shipping papers, emergency response information, and communication requirements

How must hazardous waste be identified on a shipping paper?

  1. The word "Waste" must follow the hazard class
  2. No special marking is required if the waste is placarded
  3. The letters "HW" must replace the UN identification number
  4. The word "Waste" must precede the proper shipping name Correct answer.

Explanation

For hazardous waste, the word Waste must precede the proper shipping name in the basic description, for example "Waste UN1203, Gasoline, 3, PG II." This placement ensures the waste status is immediately visible. Substituting codes or omitting the word does not comply.

Question 42Shipping papers, emergency response information, and communication requirements

A carrier uses a commercial electronic shipping paper system in the cab. Under the regulations, what must be true for the driver to rely on it?

  1. The shipper must retain the only copy
  2. The electronic record must be readily accessible and capable of being displayed to an enforcement officer Correct answer.
  3. The system must be connected to the internet continuously
  4. A paper copy must also be carried at all times

Explanation

Electronic shipping papers are permitted when the record is readily accessible in the vehicle and can be displayed to inspectors or responders on request. Continuous internet connectivity is not required, and a duplicate paper copy is not mandatory. The key is accessibility.

Question 43Shipping papers, emergency response information, and communication requirements

What is the purpose of the emergency response information required to accompany a hazardous materials shipment?

  1. To document that the driver completed hazmat training
  2. To satisfy insurance underwriting requirements
  3. To provide responders with immediate guidance for handling an incident involving the material Correct answer.
  4. To record the shipper's manufacturing batch numbers

Explanation

Emergency response information exists so that drivers, inspectors, and emergency responders have immediate guidance on hazards, protective actions, and first aid during an incident. It is a safety document, not an insurance, training, or production record.

Question 44Shipping papers, emergency response information, and communication requirements

A shipping paper shows a 24-hour emergency response number that reaches a recorded message directing callers to leave details. Does this satisfy the requirement?

  1. Yes, if the recording is updated monthly
  2. No, because the number must be monitored by a person who can provide response information Correct answer.
  3. Yes, because a recording is monitored electronically
  4. No, unless the recording is in Spanish and English

Explanation

The emergency response telephone number must be monitored at all times by a person who is knowledgeable about the material and can provide immediate guidance. A recording that only takes messages does not provide that capability. Language options or update schedules do not cure the deficiency.

Question 45Shipping papers, emergency response information, and communication requirements

Which individual may be listed as the emergency response contact on a shipping paper?

  1. The driver of the vehicle
  2. Any employee of the shipper who answers the main switchboard
  3. A person who has knowledge of the material's hazards and can provide response guidance Correct answer.
  4. The consignee's receiving clerk

Explanation

The contact must be able to provide information on the hazards and appropriate emergency response for the material, and the number must be monitored continuously. A general switchboard, receiving clerk, or the driver does not meet that standard.

Question 46Shipping papers, emergency response information, and communication requirements

A shipping paper lists a hazardous material with no packing group shown. Which situation best explains this?

  1. The shipper forgot to assign one and the paper is invalid
  2. The material is being transported in a bulk packaging
  3. The material has been assigned no packing group for its hazard class Correct answer.
  4. The material is exempt from all shipping paper requirements

Explanation

Some hazard classes and divisions do not have packing groups, so no packing group appears in the basic description for those materials. A blank packing group is not automatically an error. Bulk packaging status and exemptions do not explain the omission.

Question 47Shipping papers, emergency response information, and communication requirements

When must the shipper provide the emergency response telephone number on the shipping paper?

  1. Only when the shipment requires placards
  2. For every shipment of hazardous material requiring shipping papers Correct answer.
  3. Only for international shipments
  4. Only when the material is a hazardous waste

Explanation

Emergency response information, including the 24-hour number, is required for hazardous materials shipments that require shipping papers, regardless of whether placards are ultimately displayed. Placarding thresholds and waste status do not define when the number is needed.

Question 48Shipping papers, emergency response information, and communication requirements

A driver's shipping paper shows the proper shipping name in lowercase letters and the hazard class in a different font. What is the primary concern?

  1. Font changes are prohibited by the regulations
  2. Lowercase letters automatically void the shipping paper
  3. The paper must be reprinted by the shipper before movement
  4. The basic description must be legible and in the required sequence, and formatting must not obscure the required elements Correct answer.

Explanation

The regulations focus on the required elements being present, legible, and in the correct sequence so they can be read quickly. Minor typographic variation does not by itself invalidate a shipping paper, but formatting that obscures required information is a problem. Automatic voiding and absolute font rules are not accurate.

Question 49Shipping papers, emergency response information, and communication requirements

What information about the total quantity of hazardous materials must appear on a shipping paper?

  1. The number of packages only
  2. The value of the shipment
  3. The number of pallets used
  4. The total quantity by weight or volume, with the unit of measurement Correct answer.

Explanation

Shipping papers must show the total quantity of hazardous materials covered by the description, expressed by weight or volume with the unit of measure. Package counts alone are not the required quantity statement. Shipment value and pallet counts are not part of the requirement.

Question 50Shipping papers, emergency response information, and communication requirements

During a roadside inspection, an officer asks to see the hazardous materials shipping paper. The driver has it stored in a folder behind the seat. What is the correct assessment?

  1. This is acceptable because the paper is inside the vehicle
  2. The paper must be within immediate reach or readily accessible, and storage that delays production may violate the requirement Correct answer.
  3. The paper may be stored anywhere as long as it is in the truck
