CDL stands for commercial driver’s license. If you wish to operate a commercial motor vehicle (CMV), you will need to have your CDL.

There are 3 classes of CDL:

  1. Class A (Combination Vehicles) – Example would include tractor trailers.
  2. Class B (Heavy Straight Vehicles) – Example would include transit busses.
  3. Class C (Small Vehicles) – Example would include any vehicle used to transport 16 or more passengers or to transport hazardous materials.

The diagram below can be used to help you determine which class of CDL license you will need.

  1. Be 18+
  2. Have a driver’s license in the state you are applying
  3. Pass the CDL written knowledge test
  4. Get a physical and pass your medical exam
  5. Get fingerprints taken
  6. Go to DMV to pay fees and pass the skills test

Our CDL prep covers all the topics that you may be tested on when taking the actual CDL exam. Every practice exam includes multiple choice questions, automatic scoring, and detailed answer explanations.

We have split our practice tests up into different categories – just like the actual exam. You will find multiple practice exams for each category.

These exams are perfect to implement along with a CDL study guide. You can test your knowledge and see what you know, and what you do not know.

Does your free CDL practice test cover the subjects tested on the actual exam?

Yes. We offer practice exams for all the subjects tested on the actual CDL test. We have even split the exams up into the same categories that you will find on the actual exam.

How many times should I take the practice exams?

We recommend taking the practice exams until you are comfortable with the material. You can use the CDL test questions and answers to become familiar with the format of the exam.

Does everyone have to take the CDL general knowledge test?

Yes, everyone who wants to earn a CDL license, regardless of class, will have to take and pass the general knowledge exam. Other exams will depend on your class and which endorsements you need or want.
