If you wish to drive on Nevada streets and highways, you'll need a Nevada driver's license or learner's permit. Your vision will be screened to ensure that you satisfy the minimum vision requirements. The Nevada DMV written test includes questions on traffic laws, road rules, road signs, highway signs and markings, and safe driving practices, as well as information from the Nevada Driver's Manual. Using a cell phone while taking the drive test will result in an automatic failure. There are 50 questions on the NV DMV written test, and you must get at least 40 accurate answers to pass (80%).
