You will place placards on hazardous material shipments based on the quantity and hazard class. In order to decide what placard(s) to use on the outside of the vehicle, what must you know?

  • The material's hazard class.
  • You must know all three of these
  • The amount of all hazardous materials of all classes on your vehicle.
  • The amount of hazardous materials being shipped by this particular shipper

Placard hazardous materials shipments based on the quantity and hazard class. You can decide which placards to use if you know these three things:

  • Material's hazard class.
  • Amount being shipped.
  • Amount of all hazardous materials of all classes on your vehicle.

Normally the driver will not have to figure out what placards to use. The shipper is responsible for determining which placards to use and will supply those placards for you.

One exception may happen if you make multiple hazardous materials pickups for the same shipment. Each shipper will know what placards must be used for their particular shipment, but they won't know what placards are needed based on the sum of all of your hazardous shipments. Your company will help you determine this. In 15 years of driving, I never ran into this situation, but it can happen.

Which of the following are NOT true about ABS?

  • ABS will compensate for bad brakes or poor brake maintenance.
  • ABS will not increase or decrease ultimate stopping power — ABS is an “add-on” to your normal brakes, not a replacement for them.
  • ABS will not necessarily shorten stopping distance. ABS will help maintain vehicle control but not always shorten stopping distance.
  • ABS will not allow you to drive faster, follow more closely or drive less carefully.
  • ABS will not allow you to drive faster, follow more closely or drive less carefully.
  • ABS will not prevent power or turning skids — ABS should prevent brake-induced skids but not those caused by spinning the drive wheels or going too fast in a turn.
  • ABS will not necessarily shorten stopping distance. ABS will help maintain vehicle control but not always shorten stopping distance.
  • ABS will not increase or decrease ultimate stopping power — ABS is an “add-on” to your normal brakes, not a replacement for them.
  • ABS will not change the way you normally brake. Under normal brake conditions, your vehicle will stop as it always stopped. ABS only comes into play when a wheel would normally have locked up because of over braking.
  • ABS will not compensate for bad brakes or poor brake maintenance.
  • Remember: The best vehicle safety feature is still a safe driver.
  • Remember: Drive so you never need to use your ABS.
  • Remember: If you need it, ABS could help to prevent a serious crash.

    CDL Practice Tests

    Our CDL practice tests are designed to help test your knowledge of the CDL Manual and sharpen your skills for taking the CDL permit and endorsement exams. They are not designed to teach you the knowledge necessary to pass the exams. Please do not try to memorize CDL practice tests in order to get your CDL. There's a better way.

    Our High Road CDL Training Program is by far the easiest and most effective way to learn the materials necessary for passing your written CDL exams and preparing for a great start to your career. We strongly suggest using the High Road (which is 100% free!) to learn the CDL manual before using our CDL practice questions to test your knowledge.

    How to Pass CDL Permit Test the First Time

    The Class A CDL permit exam consists of a multiple choice test covering 20 different areas related to commercial driving. To prepare for this test, it is important to do practice tests beforehand. Knowing your personal study habits, getting enough rest, and eating a healthy breakfast will also set you up for success.

    Tips For Passing the Commercial Driver's License (CDL) Permit Test

    • Practice Makes Perfect: The best way to both mentally and physically prepare for the written exam is to take practice tests. Start out with open-book tests and gradually work your way up to giving yourself a time limit. Finally, before the big day, take a practice exam as if it were the real thing without any help. This will give you a good indication of how well you understand the material.
    • Understand Instead of Memorize: Memorizing information can be helpful for the written exam, but the key to being fully prepared is to understand the material rather than just memorizing it. Understanding the material will allow you to answer questions correctly no matter how they are worded.
    • Real World Applications: When struggling to understand concepts, create real-world scenarios to make the information more relevant to your life. Doing this will make it easier to remember come test time.
    • Utilize Study Strategies: Utilizing study strategies such as flashcards, songs, rhymes, and phrases can help you remember the material.
    • Be Fresh and Alert: The night before the exam, get a good night's sleep and eat a filling breakfast on the morning of the exam. This will ensure you are fresh and alert to take your exam.
    • Begin Early and Space out Your Studying: It is important to give yourself ample time before the exam to get familiar with the material and get your mind ready for the big day. Consider taking a training course online or in-person, if it's required. Shop around for a course that works best for you.
    • By following these tips, you will be well prepared for your written CDL exam and on your way to a successful career.
