Go!When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- Rearward
- Forward
- It doesn't matter.
- Straight up and down.
Requirements for securing the pipe
Secure each pipe with tiedowns through the pipe.
Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45� with the horizontal when viewed from the side of the vehicle, whenever practicable.
Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45� with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
You receive a scale ticket and your drive axles are 32,200 and your trailer tandems are 35,100. Based upon the two most common tandem slider rail hole spacings, what is the minimum number of holes you would have to slide the tandems to get the weight legal, and in which direction?
- 6 inch spacing - slide tandems back 3 holes
4 inch spacing - slide tandems back 5 holes - 6 inch spacing - slide tandems forward 2 holes
4 inch spacing - slide tandems forward 4 holes - 6 inch spacing - slide tandems back 2 holes
4 inch spacing - slide tandems back 4 holes - 6 inch spacing - slide tandems forward 3 holes
4 inch spacing - slide tandems forward 5 holes
With 6 inch spacing you're moving 400 pounds per hole so you need to move 3 holes to shift a minimum of 1,100 pounds (400 x 3 = 1,200).
With 4 inch spacing you're moving 250 pounds per hole so you need to move 5 holes to shift a minimum of 1,100 pounds (250 x 5 = 1,250).
Which statement is correct about the S-cam function in an air brake system?
- The S-cam forces the brake linings away from the hub and presses them against the outside of the brake drum. When you release the brake pedal, the S-cam rotates back and a knob pulls the brake shoes away from the drum, locking up the wheels
- The S-cam forces the brake shoes away from one another and presses them against the inside of the brake drum. When you release the brake pedal, the S-cam rotates back and a spring pulls the brake shoes away from the drum, letting the wheels roll freely again.
- None of these are correct
- The S-cam forces the brake drums away from one another and presses the liners against the inside of the brake chamber. When you release the brake pedal, the V-cam rotates back and a spring pulls the brake shoes away from the drum, letting the wheels roll freely again.
S-cam Brakes. When you push the brake pedal, air is let into each brake chamber. Air pressure pushes the rod out, moving the slack adjuster, thus twisting the brake camshaft. This turns the S-cam (so-called because it is shaped like the letter “S”). The S-cam forces the brake shoes away from one another and presses them against the inside of the brake drum. When you release the brake pedal, the S-cam rotates back, and a spring pulls the brake shoes away from the drum, letting the wheels roll freely again.
Your trailer has a 6 inch hole spacing in the tandem slider rail and your trailer tandems are 900 pounds overweight. What is the minimum number of holes you will have to slide the tandems to get the tandems within legal limits?
- 1 hole
- 3 holes
- 4 holes
- 2 holes

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.

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.
