Sample Arizona HazMat Test Questions

Question 1

At a railroad grade crossing where a stop is required, how far from the nearest rail must a placarded commercial vehicle stop?

  1. A 10 to 20 feet
  2. B 15 to 20 feet
  3. C 15 to 50 feet
  4. D 20 to 50 feet

Correct answer: C – 15 to 50 feet

Federal motor-carrier rules require the stop to be within 50 feet of the tracks but no closer than 15 feet. The Arizona CDL manual presents this as a 15-to-50-foot stopping distance. After stopping, the driver must check for approaching rail equipment and cross in a gear that does not require shifting.

Question 2

If “INHALATION HAZARD” appears on a shipping paper or package, the required poison-inhalation or poison-gas placard must be displayed even below the usual 1,001-pound threshold.

  1. A True
  2. B False

Correct answer: A – True

The Arizona CDL manual states that POISON GAS or POISON INHALATION placards are required even for small amounts when “INHALATION HAZARD” appears. Federal hazardous-materials rules require the appropriate placard on each side and each end, in addition to other placards required for the material. The ordinary Table 2 weight exception does not remove this requirement.

Question 3

For a non-exclusive-use vehicle carrying Class 7 (Radioactive) packages, what is the maximum combined transport index?

  1. A 10
  2. B 25
  3. C 50
  4. D 100

Correct answer: C – 50

Federal rules limit the sum of package transport indices in a non-exclusive-use vehicle to 50. The transport index indicates the degree of control needed to limit radiation exposure during transportation. An exclusive-use consignment is subject to different conditions and does not have this same combined transport-index limit.

Question 4

At a non-exempt railroad crossing, must a vehicle carrying 100 pounds of Division 4.3 material stop before the tracks?

  1. A Yes
  2. B No
  3. C Only when a train can be seen or heard
  4. D Only when warning lights are flashing

Correct answer: A – Yes

Federal placarding rules require a DANGEROUS WHEN WET placard for any amount of Division 4.3 material. A placarded vehicle must stop at a railroad crossing unless an applicable crossing exception applies. The Arizona manual instructs the driver to stop between 15 and 50 feet from the nearest rail.

Source: Arizona Commercial Driver License Manual — § 9.3.8, “Placard Tables”; § 9.6.12, “Stop Before Railroad Crossings”, 49 CFR § 172.504(e) — General Placarding Requirements, 49 CFR § 392.10 — Railroad Grade Crossings; Stopping Required

Question 5

Division 1.1 or 1.2 explosives may not be carried in a vehicle combination that includes which equipment?

  1. A A cargo tank required to be marked or placarded
  2. B Two cargo-carrying vehicles in total
  3. C A full trailer with a 200-inch wheelbase
  4. D An unmarked dry-van trailer

Correct answer: A – A cargo tank required to be marked or placarded

Federal highway-carriage rules prohibit Division 1.1 or 1.2 explosives in a combination containing a cargo tank that must be marked or placarded. The rules also prohibit combinations with more than two cargo-carrying vehicles or a full trailer having a wheelbase under 184 inches. A 200-inch wheelbase does not trigger that restriction.

Question 6

Which information must be displayed as part of the hazardous-material markings on cargo tanks, portable tanks, and other bulk packages?

  1. A The shipper’s telephone number
  2. B The material’s identification number
  3. C The package’s empty weight
  4. D The driver’s endorsement number

Correct answer: B – The material’s identification number

Federal marking rules require the appropriate hazardous-material identification number on bulk packaging. This includes cargo tanks, portable tanks, and other bulk packages. The number is taken from the Hazardous Materials Table and is commonly displayed on an orange panel, a placard, or an authorized white square-on-point marking.
