There is no better place than Colorado to explore the great outdoors. Whether you’re going up the hill or towards the mountains, you won’t have to travel far to appreciate the natural beauty it has to offer. Although you won’t be seeing much if you need a Colorado driver’s license. That’s why you need to brush up on your knowledge of the rules and regulations that drivers must follow before you explore the High Country. Otherwise, you’ll be wearing out the soles of your snow boots down in the basin.
While you may already know some of the basic highway safety rules, the Colorado driver’s license knowledge test may contain some questions that are difficult to answer. Colorado requires you to answer 80% of the 25 questions correctly on your official driver’s knowledge test to receive a passing score. You’re not going to get there by messing around on the bunny slope. You’ll need to find a black diamond-level resource to thoroughly prepare you. Look no further! There is a resource available to you that can deliver the results you need.
This free Colorado DMV Diagnostic Driving practice test, based on the most recent Driver’s Handbook (Colorado DMV Handbook (CO Driver's Manual) 2025), has a proven record of preparing drivers to pass the official knowledge test on the first attempt. The practice test is up to date as of October 2025. It contains 15 of the most commonly missed questions like the ones on the official knowledge test. This technique allows you to concentrate your study on the more complex questions and spend less time on the ones you already know the answer to. The practice test is better than a study guide because it provides you with a detailed explanation of the answer to any question you miss. Study guides are designed for you to memorize the answers to questions. The practice test equips you with valuable information that can be used to improve your test score and apply to your daily driving performance.
