Missouri requires both a 25-question written test and a separate road signs test to receive your permit or license. The written knowledge exam will be multiple-choice and based on the 2024 Missouri Driver’s Guide, featuring questions regarding road situations, traffic fines, road signage, driving under the influence, and license restrictions. To pass the knowledge test, you’ll need to correctly answer at least 20 of the 25 questions. If you’re applying for your permit, you must be at least 15 years old, pass the written and road signs tests, as well as a basic vision test, pay the $3.50 permit fee, provide various proofs of identity and residency, as well as have a parent or guardian present to provide consent. If you are 16 or older, you may apply for your intermediate license once you have held your permit for six months, pass the driving exam, and pay the $7.50 license fee. If you’re 18 or older, you may opt to take all your tests -- written, road signs, vision, and driving -- in one go and pay a $10-20 license fee. This DOR practice test will focus on just chapter 3 of the driver’s guide: Pavement Markings, Traffic Signs, and Signals. It is extremely useful, as it will prepare you for both the general written and specific road signs tests.
