Ready to test your CDL knowledge? This powerful Texas CDL General Knowledge Practice Test has been designed to help you quickly determine where you stand when it comes safely operating a commercial motor vehicle (CMV). The general knowledge test is required to be taken by all applicants looking to get their CDL so don’t skip this free practice.  Expect to see questions that will test your knowledge of traffic signs, signals, right-of-way rules, trucking laws, speed limits, vehicle inspection, and basic commercial vehicle safety.

Just like the real exam, each of the 50 multiple-choice questions is based on the information found in the official Texas CDL Handbook.   You will need to answer 80% of the questions correctly to pass.  Each question includes 4 potential answers and a detailed explanation to help ensure you fully understand the material.  It is recommended that you take the time to review the explanations to gain some further insight into the concepts being tested.  When stopped on a hill, what is the proper procedure to start moving without rolling back? When the road is slippery, will retarders help keep you from skidding? These are just a few examples of the types of questions you can expect to encounter on the real test.  If you don’t know the answers to these questions, its time to begin your study session.

A career in trucking starts with acquiring a CDL but you have to pass the written test first. Don’t waste your time or money by failing the test.  A failed exam means not only additional testing fees but wasted time as you will be required to schedule another appointment and take the exam again. Take the first step toward your trucking career and start practicing now!
