To obtain a CDL (Commercial Driver’s License), you must pass several theory and written exams and meet other requirements. Your knowledge of general commercial driving theory will be evaluated through 50 multiple-choice questions on the official General Knowledge Exam. A few of these questions are about the pre-trip inspection, which every commercial driver must perform before they get behind the wheel. You must also correctly perform a pre-trip inspection during your CDL skills tests, so it is crucial to master it during your learning phase.
To support your studies, we have created a series of Colorado CDL Pre-Trip Inspection Practice Tests. Now you’re about to take the second practice test in this series. It includes several questions based on the official Commercial Driver’s License Manual (Colorado CDL Handbook 2026), specifically Section 11 (Vehicle Inspection).
You must answer all questions and score 80% or higher to pass, leaving little room for error. We recommend keeping track of your scores. With more practice, you will observe the gradual progress that naturally occurs as you become more familiar with this subject. Once you consistently achieve passing scores above 90% on this practice test, you can continue your study with our Free Colorado CDL Permit Practice Test.
