You must have a driver's license or learner's permit if you want to operate any motor vehicle on Mississippi's streets or highways. Your eyes will be tested as part of the examination to ensure that you can see clearly enough to drive safely. The written knowledge test covers information from the Mississippi Driver's Manual, including traffic laws, road signs, road rules, and safe driving practices. The MS DMV knowledge test has 30 questions, and you must answer 24 of them correctly to pass (80%). Let's start with our Mississippi driver's permit test now.
