Sample Colorado HazMat Test Questions

Question 1

Before driving a vehicle containing hazardous materials past an open fire, what must the driver determine?

  1. A That the load includes some nonflammable material
  2. B That the vehicle has an automatic sprinkler system
  3. C That the vehicle can pass the fire safely without stopping
  4. D That the vehicle can remain at least 100 feet from the flames

Correct answer: C – That the vehicle can pass the fire safely without stopping

Federal motor-carrier rules prohibit operating a vehicle containing hazardous materials near an open fire until the driver has determined that it can pass safely without stopping. Colorado’s CDL manual gives the same direction for placarded vehicles. A vehicle containing hazardous materials also may not be parked within 300 feet of an open fire.

Question 2

A vehicle carries combustible liquid only in non-bulk packages. At what aggregate gross weight is placarding generally required?

  1. A 100 pounds or more
  2. B 500 pounds or more
  3. C 1,001 pounds or more
  4. D Any amount

Correct answer: C – 1,001 pounds or more

Combustible liquid is listed in Placard Table 2. For non-bulk packages, the federal exception applies when the aggregate gross weight of all Table 2 material is less than 1,001 pounds. At 1,001 pounds or more, placarding is generally required. Bulk packages and materials subject to special placarding provisions are not covered by this weight exception.

Question 3

You already have dry silver cyanide aboard when offered cartons of battery acid. How should these materials be handled?

  1. A Load the acid only if every carton remains upright
  2. B Place the acid above the silver cyanide
  3. C Cover the silver cyanide with a secure tarp
  4. D Do not load the materials together

Correct answer: D – Do not load the materials together

Federal segregation rules prohibit loading or transporting cyanides with acids when mixing them could generate hydrogen cyanide. The CDL manual specifically lists silver cyanide among the cyanides that must be kept apart from acids, corrosive materials, or other acidic materials capable of causing that reaction. Changing the stacking order or covering one package does not satisfy the segregation requirement.

Question 4

Where must a placarded hazardous-materials vehicle stop before the nearest rail at a required railroad crossing?

  1. A Between 10 and 20 feet away
  2. B Between 15 and 20 feet away
  3. C Between 15 and 50 feet away
  4. D Between 20 and 50 feet away

Correct answer: C – Between 15 and 50 feet away

Federal motor-carrier rules require covered vehicles to stop within 50 feet of, but no closer than 15 feet to, the railroad tracks. The driver must look and listen for trains and determine that none is approaching. When safe, the vehicle must cross in a gear that permits it to clear the tracks without shifting gears.

Question 5

Which motor-vehicle shipment may qualify for an exception from the shipper-certification requirement?

  1. A A shipment whose description does not contain the letters RQ
  2. B A vehicle displaying every required placard
  3. C A shipment that was packaged incorrectly
  4. D A non-waste shipment transported by the shipper as a private carrier and not being reshipped or transferred

Correct answer: D – A non-waste shipment transported by the shipper as a private carrier and not being reshipped or transferred

Federal rules generally require the person offering hazardous material for transportation to certify that the shipment complies with applicable requirements. One motor-vehicle exception covers a non-waste hazardous material transported by the shipper as a private carrier, unless it will be reshipped or transferred between carriers. A carrier-supplied cargo tank is another listed exception. Proper placarding alone does not remove the certification requirement.

Question 6

Before Colorado may issue a hazardous-materials endorsement, which agency must provide a determination that the applicant poses no security threat?

  1. A The Federal Motor Carrier Safety Administration
  2. B The Pipeline and Hazardous Materials Safety Administration
  3. C The Transportation Security Administration
  4. D The National Highway Traffic Safety Administration

Correct answer: C – The Transportation Security Administration

The Transportation Security Administration conducts the security threat assessment for a hazardous-materials endorsement. Federal regulations prohibit a state from issuing or renewing the endorsement unless TSA provides a Determination of No Security Threat. This requirement is separate from the hazardous-materials knowledge test and, for a first-time endorsement applicant, the required entry-level driver training.
