Sample Maryland HazMat Test Questions

Question 1

What is the primary purpose of properly packaging hazardous materials?

  1. A To identify the material’s hazard class
  2. B To contain the material during transportation
  3. C To simplify the driver’s loading duties
  4. D To replace shipping papers and labels

Correct answer: B – To contain the material during transportation

Hazardous-material packaging is intended to contain the product and protect people and the environment from contact or release. Federal rules require packages to be prepared so that no identifiable release occurs under conditions normally encountered during transportation. The Maryland manual separately explains that labels, placards, shipping papers, and emergency information communicate the material’s risks.

Source: Maryland Commercial Driver’s License Manual — § 9.1.1, “Contain the Material”; § 9.1.2, “Communicate the Risk”, 49 CFR § 173.24(b)(1) – General requirements for packagings and packages

Question 2

Before hauling hazardous materials over an unfamiliar route, when should you determine the required route and obtain necessary permits?

  1. A After the trip has begun
  2. B Before starting the trip
  3. C Only if no hazardous-waste manifest is provided
  4. D Only if the vehicle does not have GPS navigation

Correct answer: B – Before starting the trip

Determine permit and routing requirements before the trip and make sure all required papers are available before starting. State and local requirements may restrict certain roads, bridges, or tunnels and can change. A company driver should consult the dispatcher, while an independent driver planning a new route should check with the appropriate agencies along the route.

Question 3

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

  1. A The carrier’s insurance policy
  2. B Personal health-insurance information
  3. C A copy of the written route plan
  4. D The vehicle’s fuel receipts

Correct answer: C – A copy of the written route plan

A written route plan must be prepared before a vehicle transports Division 1.1, 1.2, or 1.3 explosives, and the driver must receive and carry a copy. The driver may prepare the plan as the carrier’s agent when the trip begins somewhere other than the carrier’s terminal. The Maryland manual also instructs the driver to follow the plan throughout the shipment.

Question 4

At a railroad grade crossing where placarded hazardous-material vehicles must stop, does a 100-pound Division 4.3 load trigger the stop requirement?

  1. A Yes, because any amount of Division 4.3 requires placarding
  2. B No, because the load weighs less than 1,001 pounds
  3. C Only when a train can be seen or heard
  4. D Only when the material is carried in a cargo tank

Correct answer: A – Yes, because any amount of Division 4.3 requires placarding

Division 4.3 dangerous-when-wet material requires placarding in any quantity. Federal railroad-crossing rules require a placarded commercial vehicle carrying this classification to stop at crossings covered by the rule. Posted exempt crossings and certain traffic-controlled crossings are among the exceptions that must be considered separately.

Source: 49 CFR § 172.504(e) – General placarding requirements, 49 CFR § 392.10(a)(3), (b) – Railroad grade crossings; stopping required

Question 5

When may a non-hazardous product be described on a shipping paper with a hazard class or hazardous-material identification number?

  1. A When the product is a liquid
  2. B When the product is a solid
  3. C Whenever the driver believes the description would be helpful
  4. D Never

Correct answer: D – Never

A product that is not hazardous material may not be described using a hazard class or hazardous-material identification number. Those entries communicate regulated hazards to carriers and emergency responders. Using them for a non-hazardous product could falsely identify the shipment as hazardous material.

Question 6

What is the primary purpose of the Emergency Response Guidebook?

  1. A To establish hours-of-service limits
  2. B To guide first responders during the initial response to hazardous-material incidents
  3. C To approve hazardous-material transportation routes
  4. D To replace the shipment’s shipping papers

Correct answer: B – To guide first responders during the initial response to hazardous-material incidents

The ERG provides initial-response information for firefighters, police, and others handling a hazardous-material incident. Responders can use the proper shipping name or identification number to locate appropriate protective and emergency actions. The Maryland manual emphasizes that accurate shipping papers, labels, and placards help responders use the guide correctly.
