Which of the following is true about driving through a curve in a truck with a high center of gravity?

  • Trucks with a high center of gravity can go around a curve a little more quickly than a truck with a lower center of gravity
  • Ride the brakes slightly in the curve. This will help you keep control.
  • Be in a gear that will let you accelerate slightly in the curve. This will help you keep control.
  • Staying on the brake while slightly pressing the accelerator at the same time will balance the forces throughout the curve, making the truck more stable
Slow to a safe speed before you enter a curve. Braking in a curve is dangerous because it is easier to lock the wheels and cause a skid. Slow down as needed. Do not ever exceed the posted speed limit for the curve. Be in a gear that will let you accelerate slightly in the curve. This will help you keep control.
You will not normally be on the accelerator through the curve, but that is how you handle an emergency. This is an advanced technique, so don't worry about this just yet. Focus on getting your speed down where it needs to be before you enter the curve.

There are three rules for using turn signals:

  • Signal when necessary only, signal more at night, signal others
  • None of these are true
  • Signal your intentions, signal what's coming, cancel your signal
  • Signal early, signal continuously, cancel your signal.

Turns. There are three rules for using turn signals:

  • Signal early. Signal well before you turn. It is the best way to keep others from trying to pass you.
  • Signal continuously. You need both hands on the wheel to turn safely. Do not cancel the signal until you have completed the turn.
  • Cancel your signal. Do not forget to turn off your turn signal after you have turned (if you do not have self-canceling signals).
This is very important advice. Letting others know your intentions is critical for avoiding accidents.

During the 14-consecutive-hour, on-duty period, you can only drive your truck for up to how many total hours?

  • 10.5
  • 11
  • 14
  • 10
During the 14-consecutive-hour, on-duty period, you are only allowed to drive your truck for up to 11 total hours. Once you have driven a total of 11 hours, you have reached the driving limit and must be off duty for another 10 consecutive hours before driving your truck again. You can think of this as a window of opportunity. You have a 14-hour window of opportunity, in which you can drive your truck for 11 hours. This 11-hour driving limit is also reset when you take your 10-hour break. Both the 14-hour clock and the 11-hour clock are fully reset after logging 10 hours off duty.

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.
