What is the main factor affecting the low-speed offtracking of a tractor trailer?

  • The length of the trailer, regardless of the position of the trailer tandems
  • The ratio of the length of the tractor to the length of the trailer
  • The distance from the trailer kingpin to the center of the trailer rear axle
  • The distance from the steer axle to the drive axles

When a combination vehicle makes a low-speed turn - for example a 90-degree turn at an intersection - the wheels of the rearmost trailer axle follow a path several feet inside the path of the tractor steering axle. This is called low-speed offtracking. Excessive low-speed offtracking may make it necessary for the driver to swing wide into adjacent lanes to execute the turn (that is, to avoid climbing the inside curbs or striking fixed objects like telephone poles).

This performance attribute is affected primarily by the distance from the trailer kingpin to the center of the trailer rear axle, otherwise known as the wheelbase of the semitrailer. To prevent trucks from being too long to maneuvering safely around turns encountered in cities and towns, the maximum length allowed from the kingpin to the trailer tandems is set by the individual states.

Which of the following is true about using your horn?

  • It can startle others and could be dangerous when used unnecessarily.
  • All of these are correct
  • It can help to avoid a crash
  • Your horn can let others know you are there.
Use Your Horn When Needed. Your horn can let others know you are there. It can help to avoid a crash. Use your horn when needed; however, it can startle others and could be dangerous when used unnecessarily.
Be very careful about startling people with your horn. Everyone considers tractor-trailer air horns to be an imminent warning of impending doom! You will have a "city horn" to go along with your air horn. The city horn sounds just like a car horn. Use that if you can get the job done with it, otherwise use the air horn.

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.
