Missouri residents know their barbeque, beer, and gooey butter cake. However, how much you know about the rules of the road will affect your ability to see what lies beyond The Gateway Arch. Don’t be put out! If the only thing you’re missing is a Missouri driver’s license, a little study time and a dose of determination will set you on a course to new discoveries. The first thing you will need to do is develop a plan to achieve your goals.
While you may be familiar with the fundamentals of safe driving, you will need to demonstrate a more advanced level of the subject matter. Missouri requires that you answer 80% of the 25 driver’s license knowledge test questions correctly to get an instruction permit. If you’re going to negotiate the curves on the highway, you’d better prepare yourself for the ones the written knowledge test will throw at you. With multiple-choice questions, the official knowledge test challenges you to carefully analyze the possible answers and carefully choose the correct one. You’ll need a clear understanding of the questions to be successful.
Our free Missouri DOR Diagnostic Driving practice test is based on the most recent Missouri Driver Guide (Missouri DOR Handbook (MO Driver's Manual) 2025) and is up to date as of October 2025. This practice test is expertly designed to prepare users for the difficult questions on the official written knowledge test. Better than a study guide, the practice test provides you with information you can count on to pass your knowledge test on the first try. There are 15 questions on the official knowledge test that most Missourians miss. The practice test includes questions just like the ones commonly missed to guide you around their complexities. If you submit an incorrect answer, you will immediately receive detailed feedback containing the information that would make the answer correct. This approach equips you with a thorough understanding of the information needed to answer correctly, instead of having you merely memorize the correct answer.
You may not be in the other Kansas City, but you will find practice tests covering the entire nation at https://driving-tests.org/academy/drivers-license.
