Residents must have an Oregon driver's license or learner's permit to operate a motor vehicle on any Oregon street or highway. Your vision will be tested by the DMV to ensure that you can see clearly enough to drive safely. The Oregon DMV written test will include questions about Oregon road rules, traffic laws, road signs, and safe driving practices, all of which will be based on the contents of the Oregon Driver's Manual. You must wait at least one day after failing your OR DMV knowledge test to retake the test. There are 35 questions on the test, and you must get at least 28 accurate answers to pass (80%). Prepare for the official Oregon DMV driver's license test by practicing with our Oregon DMV practice test and studying the manual.
