Whether or not you load and secure the cargo yourself, you are responsible for:
Inspecting your cargo.
Recognizing overloads and poorly balanced weight.
Knowing your cargo is properly secured and does not obscure your view ahead or to the sides.
Knowing your cargo does not restrict your access to emergency equipment.
The driver is ultimately responsible for the cargo. The driver must ensure the cargo is loaded safely, is properly secured, and the weight is distributed evenly.
Apply the brakes as hard as you can so that the wheels lock. Keep the wheels locked and the steering wheel movements very small while doing this. If you need to make a larger steering adjustment, release the brakes. Re-apply the brakes as soon as you can.
Turn the wheel while applying the brakes hard enough to lock the drive tires. The drive tires locking will produce more grip on the roadway, giving you more braking force and more control.
Apply the brakes as hard as you can without locking the wheels. Keep steering wheel movements very small while doing this. If you need to make a larger steering adjustment or if the wheels lock, release the brakes. Re-apply the brakes as soon as you can.
Controlled Braking. With this method, you apply the brakes as hard as you can without locking the wheels. Keep steering wheel movements very small while doing this. If you need to make a larger steering adjustment or if the wheels lock, release the brakes. Re-apply the brakes as soon as you can.
The distance between the locking pin holes on the trailer will be the main factor affecting how much weight is moved per hole. This distance varies between the different trailer manufacturers, and the larger the distance between the holes, the more weight will be shifted with each hole.
When you are driving in heavy traffic, the safest speed is that of other vehicles. Vehicles going the same direction at the same speed are not likely to run into one another.
Go with the flow! Now you know where that saying comes from. Well, at least I think so!
You may divide your 10-hour break into two separate breaks. One break has to be at least 2 hours long. You can use any combination off-duty and sleeper berth time.
The other break must be a minimum of 7 hours. The longer of the two breaks must be logged as sleeper berth.
In an air brake system, the low air pressure warning signal:
Is required on vehicles with air brakes. A warning signal you can see must come on before the air pressure in the tanks falls below 200 psi (or one-half the compressor governor cutout pressure on older vehicles)
Is required on vehicles with air brakes. A warning signal you can see must come on before the air pressure in the tanks falls below 60 psi (or one-half the compressor governor cutout pressure on older vehicles)
None of these are true
Is optional on vehicles with air brakes. A warning signal you can see must come on before the air pressure in the tanks falls below 60 psi (or one-half the compressor governor cutout pressure on older vehicles)
A low air pressure warning signal is required on vehicles with air brakes. A warning signal you can see must come on before the air pressure in the tanks falls below 60 psi (or one-half the compressor governor cutout pressure on older vehicles). The warning is usually a red light. A buzzer may also come on.
When securing paper rolls with eyes crosswise, which of the following can be used to prevent side-to-side shifting when there is more than 8 inches of space to the wall?
Requirements for eyes crosswise: prevent rolls from shifting toward either wall
If there is more than a total of 203 mm (8 in) of space between the ends of a paper roll and other rolls or the walls of the vehicle, use one of these methods:
A paper roll or the forwardmost roll(s) in a group of paper rolls is not prevented from tipping or falling forward by vehicle structure or other cargo.
Paper roll width is more than 1.25 times and less than 1.76 times its diameter.
Only friction mats are used for forward securement.
Solution #4:
The friction mat alone is adequate. The friction mat allows the roll to slide on the floor without tripping the roll.
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.
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

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.
