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

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.
