Residents of California must hold a California driving license in order to drive on public roads and highways. You must provide appropriate document(s) verifying your identity, residency, birthdate, and, if eligible, your social security number when applying for a California license. A vision test, a knowledge test, and, if required, a driving test are all part of the examination. The CA DMV written test includes questions about information from the California Driver Handbook, such as road rules, safe driving practices, and signs. The DMV knowledge test has 36 questions, and you must answer 30 of them correctly to pass (83%).
