Go!If you make a quick lane change, what can happen?
- The "crack-the-whip" effect can turn the trailer over
- All these are correct
- The steering knuckle can buckle under the pressure
- The cargo's center of gravity can raise as much as 22%
Trucks with trailers have a dangerous "crack-the-whip" effect. When you make a quick lane change, the crack-the-whip effect can turn the trailer over. There are many accidents where only the trailer has overturned.
Describe the basics of drum brakes:
- To stop, the brake shoes and linings are pushed against the inside of the drum. This causes friction, which slows the vehicle (and creates heat).
- To stop, the brake chamber twists around the S-cam, forcing the linings against the outside of the drum. This causes friction, which slows the vehicle (and creates heat).
- To stop, the drum forces the brake shoes and linings in against the inside of the hub. This causes friction, which slows the vehicle (and creates heat).
- To stop, the brake lining wedges the drum against the inside of the hub. This causes friction, which slows the vehicle (and creates heat).
Brake Drums, Shoes and Linings. Brake drums are located on each end of the vehicle's axles. The wheels are bolted to the drums. The braking mechanism is inside the drum. To stop, the brake shoes and linings are pushed against the inside of the drum. This causes friction, which slows the vehicle (and creates heat). The heat a drum can take without damage depends on how hard and how long the brakes are used. Too much heat can make the brakes stop working.
A load weighing 41,500 lbs requires securement against rearward force of:
- 10,000 lbs.
- 20,750 lbs.
- 20,000 lbs.
- 41,500 lbs.
- The forward force (80% of the cargo weight) represents braking while driving straight ahead.
- The rearward force (50% of the cargo weight) represents vehicle acceleration or braking in reverse.
- The side-to-side or lateral force (50% of the cargo weight) represents traveling on a curve, ramp or changing lanes.
- The vertical force (20% of the cargo weight)) represents cargo vibration during transport. This requirement is satisfied when the cargo is "Fully Contained"

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.

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.
