These questions are very similar to the ones you'll find on the actual CDL written test you'll be taking to get your CDL license. Follow along with the test questions below and read through the explanations that follow each CDL test question to get some better insights into the CDL exam and the trucking industry itself.

1. Which of the following statements about "Radioactive" labels is true?

A. Yellow III indicates the highest level of radioactivity
B. Yellow II indicates the highest level of radioactivity
C. White I indicates the highest level of radioactivity

Answer

A. Yellow III indicates the highest level of radioactivity

The more radioactive something is, the further I'm stayin away. That's all I can say!

2. When transporting both hazardous and non hazardous materials, your bills must...

A. Describe the hazardous materials first
B. Have the hazardous materials highlighted
C. Identify the materials by the letter X or RQ in the HM column
D. Any one of the above


Answer

D. Any one of the above

There are a lot of rules regarding what hazardous materials can be transported safely with other hazardous and non-hazardous materials. Your charts will help you out with these, but the shipper is required to know by law what can be shipped together and what can not.

3. The designation RQ identifies the material's...

A. Reference Quotient
B. Regulatory Quotient
C. Reportable Quantity
D. Regulatory Quantity


Answer

C. Reportable Quantity

The reportable quantity is basically the maximum amount of any particular hazardous material that can be carried without needing a placard. If you are carrying at or above the reportable quantity, it must be placarded.

4. When transporting hazardous waste, you must...

A. Have the word "WASTE" before the name of the material on the bills
B. Sign a Uniform Hazardous Waste Manifest
C. Carry a Uniform Hazardous Waste Manifest in the truck
D. All of the above


Answer

D. All of the above

Wow, these are tough. The CDL test doesn't have that many really tough questions on it, but as you can see, you better keep studying because you never know!

A. how to ship an item
B. to what shipping mode the information on that line applies
C. how much of the material can be put in a vehicle without placarding

Wow again. That amount is also known as the reportable quantity

A. the UN or NA ID number of the product
B. the date of manufacture
C. the CHEMTREC phone number
D. the owner's PUCO or ICC number


Answer

A the UN or NA ID number of the product

When you see the words "must", "must not", or any numbers (like the number of feet you must stop before a RR crossing) in the CDL manual, make sure you try to remember what is said. They like to include those type of questions on the CDL test

7. A placarded vehicle must have at least ___ placards?

A. Two
B. Three
C. Four
D. Six


Answer

C. Four

Yap, one for each of the four sides of the vehicle. And just to be clear, they are referring to the number of placards on the outside of the vehicle, not the ones on the inside of the trailer on the individual containers.

8. Of the following hazardous material classes, which is the most dangerous?

A Division 6.1
B. Division 6.2
C. Division 6.3
D. Division 6.4


Answer

A. Division 6.1

The lower the number, the more severe the rating is.

A. the transport index and the Separation Distances Table
B. the List of Hazardous Materials and Reportable Quantities
C. the Table of Hazardous Materials
D. the Segregation and Separation Chart


Answer

A. the transport index and the Separation Distances Table

Again, there isn't much I can add to these. Most of this section of the CDL test is just memorization.

10. You should turn off your engine when loading flammable liquid unless...

A. The material does not need a placard
B. You need the engine to run the pump
C. You are a non-smoker
D. You are loading at night and need the headlights


Answer

B. You need the engine to run the pump

Does the idea of pumping out flammable liquids make you want to run the other way? Yeah, me too. I drove a food grade tanker. Milk is only dangerous if you drown yourself in it.

11. The hazardous materials will be named on...

A. The Hazardous Materials Table List
B. The List of Hazardous Substances and Reportable Quantities
C. Either one of the above lists
D. Neither of the above lists


Answer

C. Either one of the above lists

Again, memorization.

A. Products that cannot be loaded together in the same trailer

C. Products requiring special labeling
D. Products that are transported with animals


Answer

A. Products that cannot be loaded together in the same trailer

The name of the chart kinda speaks for itself.

A. Putting a label on the package
B. Putting a label on a tag attached to the product
C. Putting a label on the product
