This test is based on the official 2020 CDL Manual FREE Colorado CDL General Knowledge Test Simulator 2020

The first step to becoming a commercial driver in Colorado is passing the state CDL exam. To help you prepare for that test, we have created this powerful CO CDL General Knowledge Practice Test, which is the second test in our General Knowledge series and contains 50 more multiple choice questions.

Just like with the real test, the questions on this practice test are drawn from the topics and concepts found in the Colorado Commercial Driver License Manual. Each question has been carefully written to prepare you for the experience of sitting for the real test. On our practice test, just like on the real test, you can expect to see questions on such subjects as basic vehicle control, distracted and drowsy driving, cargo transportation, vehicle inspection and more.

For example, what are some advantages of going right instead of left around an obstacle? What is an “escape ramp?” Those are examples of the types of questions that you will answer on this practice test.

You will need to answer 80% of the questions correctly to pass but don’t worry, you can take this test an unlimited number of times. Also, any missed questions will be added to your Missed Question Bank which you can then use to focus on the areas that you need to give more attention. You must pass the General Knowledge test to earn your CDL. Make sure you are prepared to pass by taking this practice test now.
