Sample Iowa HazMat Test Questions

Question 1

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

  1. A The material may travel only by highway
  2. B The vehicle must display a POISON placard
  3. C The material may not be offered or accepted for transportation
  4. D The driver needs an additional endorsement

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

Under the federal Hazardous Materials Table, a “Forbidden” entry means the material may not be offered for transportation or accepted for transportation. It is not a placarding category and cannot be overcome by obtaining a special driver endorsement. A driver must not accept such a shipment.

Question 2

Where must hazardous-material shipping papers be kept during transportation?

  1. A Anywhere in the cab, provided they are inside the vehicle
  2. B Within immediate reach and clearly visible while driving, or in the driver-door pouch; when away from the controls, on the driver’s seat or in that pouch
  3. C Only inside the driver-door pouch
  4. D Inside the trailer with the hazardous-material packages

Correct answer: B – Within immediate reach and clearly visible while driving, or in the driver-door pouch; when away from the controls, on the driver’s seat or in that pouch

Federal rules require shipping papers to be readily accessible and recognizable. While driving, they must be clearly visible within the restrained driver’s immediate reach or stored in a holder mounted inside the driver’s door. When the driver is away from the controls, the Iowa CDL manual directs that they be left on the driver’s seat or in the door pouch.

Question 3

While transporting Division 1.1, 1.2, or 1.3 explosives, which document must the driver carry?

  1. A The carrier’s liability-insurance policy
  2. B A personal health-insurance card
  3. C A written route plan
  4. D The vehicle manufacturer’s warranty

Correct answer: C – A written route plan

Federal routing rules require the carrier or its agent to prepare a written route plan before transporting Division 1.1, 1.2, or 1.3 explosives and to give the driver a copy. If the trip begins somewhere other than the carrier’s terminal, the driver may prepare the plan as the carrier’s agent. The driver must follow the planned route.

Question 4

Which description best defines a cargo tank?

  1. A Any portable tank placed on a vehicle for a single trip
  2. B A non-bulk container intended only for explosives
  3. C Bulk packaging that must be removed before loading or unloading
  4. D A bulk tank that is attached to, forms part of, or is loaded and unloaded without removal from a motor vehicle

Correct answer: D – A bulk tank that is attached to, forms part of, or is loaded and unloaded without removal from a motor vehicle

Federal regulations define a cargo tank as bulk packaging intended primarily for liquids or gases. It may be permanently attached to the motor vehicle or constructed and attached so that it is loaded or unloaded without being removed. A portable tank, by contrast, is designed to be removed from the vehicle.

Question 5

Division 1.1 or 1.2 explosives must not be carried in a vehicle combination containing which equipment?

  1. A A marked or placarded cargo tank
  2. B A trailer equipped with air brakes
  3. C A trailer with a long wheelbase
  4. D A power unit with a sleeper berth

Correct answer: A – A marked or placarded cargo tank

Federal hazardous-materials rules prohibit transporting Division 1.1 or 1.2 explosives in a vehicle combination containing a marked or placarded cargo tank. The restrictions also address certain other incompatible hazardous materials in the combination. The presence of air brakes, a sleeper berth, or a particular wheelbase does not create this prohibition.

Question 6

Under the standard placarding rule, when may a CDL holder without a hazardous-materials endorsement transport a hazardous-material shipment?

  1. A Never, regardless of the material or quantity
  2. B Whenever the trip remains within Iowa
  3. C When the shipment does not require placards and does not otherwise require the endorsement
  4. D Whenever the carrier gives written permission

Correct answer: C – When the shipment does not require placards and does not otherwise require the endorsement

Federal CDL rules require an H endorsement for vehicles transporting hazardous material that must be placarded and for certain select agents or toxins. The Iowa CDL manual presents the general rule that a nonplacarded hazardous-material load may be driven without the endorsement. Remaining within one state or receiving carrier permission does not eliminate an endorsement requirement.
