In order to obtain a CLP (Commercial Learners Permit) which is the first step to getting a CDL, which you will need to operate any commercial vehicle, you will first have to take and pass the General Knowledge test. The general knowledge test consists of 50 multiple choice questions, and a score of 80% (40 out of 50) or better is required to pass.
