  2. B At least 3 feet away if attended
  3. C More than 15 feet away
  4. D No minimum distance applies

Correct answer: A – More than 5 feet away

A vehicle containing Division 1.1, 1.2, or 1.3 material must not be parked on or within five feet of the traveled portion of a public street or highway. To comply, it must be parked more than five feet away. Additional parking restrictions apply near certain structures and gathering places.

Question 2

What is the primary purpose of the Emergency Response Guidebook?

  1. A To provide normal driving instructions
  2. B To guide initial responses to hazardous-material incidents
  3. C To designate approved hazardous-material routes
  4. D To replace required shipping papers

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

The ERG helps firefighters, police, and other responders identify hazards and select initial protective actions during a transportation incident. It can be searched using a material’s proper shipping name or identification number. Missouri’s CDL manual emphasizes that accurate shipping papers, labels, and placards help responders use the guide effectively.

Question 3

Why must a hazardous-material shipping paper be distinctively tabbed or placed ahead of other papers?

  1. A So authorities can quickly recognize and retrieve it during an accident or inspection
  2. B So freight bills remain in alphabetical order
  3. C So the document is protected from moisture
  4. D So it can serve as the vehicle’s route plan

Correct answer: A – So authorities can quickly recognize and retrieve it during an accident or inspection

Federal rules require a hazardous-material shipping paper to be readily available and recognizable during an accident or inspection. If it is carried with other documents, it must be distinctively tabbed or placed first. The document must also be kept in the specified location depending on whether the driver is at the controls.

Question 4

Which document should you check first to determine whether a shipment contains hazardous material?

  1. A The vehicle registration
  2. B The shipping paper
  3. C The driver’s medical certificate
  4. D The fuel receipt

Correct answer: B – The shipping paper

The shipping paper identifies regulated hazardous material included in a shipment. Look for entries containing a proper shipping name, hazard class, and identification number, as well as highlighting or an “X” or “RQ” in the hazardous-material column. Packages and labels provide additional clues, but packages should not be opened merely to identify their contents.

Which method may be used to transport cylinders containing Class 2 gases?

  1. A Securely restrain them in an upright or horizontal position
  2. B Secure them in suitable racks
  3. C Pack them in boxes or crates that prevent movement or overturning
  4. D Any of the above

Correct answer: D – Any of the above

Class 2 cylinders may be restrained upright or horizontally, placed in racks, or packed in boxes or crates. Whichever method is used must prevent shifting, overturning, or ejection during normal transportation. Cylinders placed on a vehicle floor or platform must be on an essentially flat surface. Applicable pressure-relief devices must communicate with the vapor space as required.

The rule covers specified events, including many unintentional releases, and contains limited exceptions. This deadline is separate from any immediate telephone-notification requirement that may apply to a serious incident.
