FREE CA CDL General Knowledge Marathon

California Commercial Driver's License.

Ready for something really challenging? This California CDL General Knowledge Marathon is a massive practice test that contains all 330 questions from our database for this CA endorsement. If you give an incorrect answer, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. It might take some time, but you can do this!
