Vermont driver's examination

(From the 2017 Vermont driver handbook)
Number of tests: 14
Number of questions: 20
Passing score: 4
Directions: The knowledge test has 20 questions. Each question has four answers to choose from, of which only one is correct. You must answer at least 16 questions correctly to pass the test. If you fail the test, you must wait at least one day before taking another one. Computer tests have an audio track so that you may listen to questions using headphones. If you speak another language and have difficulty reading English, you may use a dictionary and also ask the examiner to assist you. If you wish to have an interpreter other than an ASL interpreter, you must provide the interpreter yourself and that person must have a valid driver license from a U.S. State or territory.
