On an appointment basis, DMV offices conduct knowledge testing for operator licensing. The information provided in the Connecticut Driver's Manual, including road signs, driving rules, and safety rules, is used to create the CT DMV written test. The DMV CT knowledge test has 25 questions, and you must answer 20 of them correctly to pass (80%). Before you get your learner's permit, you must pass a knowledge test. Before you can receive a driver's license in Connecticut, you must pass a vision test. After passing the CT DMV practice permit test, you will be eligible to arrange a road test appointment.
