You can take the test once you are at least 15 ½ years old and can provide proof that you’ve completed an in-person or online driver education course that included 50 hours of behind-the-wheel experience if you’re under 18. Questions will cover a wide range of topics, such as traffic signs, insurance requirements, the demerit point system, safe driving operations, and seatbelt laws. You’ll need to score an 80% on your exam to pass, correctly answering a minimum of 40 of the 50 questions. To get your permit or license in Nevada, you’ll need to take a written knowledge test of 50 questions. This Nevada DMV practice test has just been updated for August 2023 and covers 40 of the most essential road signs and rules questions directly from the official 2023 NV Driver Handbook.
