听力原文: To get a driver's license, you must take a series of tests. The first test is the vision test. This test checks your eyes to see if you have to wear glasses when you drive. The second test is a written test that checks your knowledge of highway and traffic regulations. You can prepare for this test by studying a booklet that you can get at the driver's license office. After you pass the written test, you receive an instruction permit. This permit allows you to practice driving with an experienced driver. The last test you have to take is a road test. This checks your driving ability. If you pass it, you will receive your driver's license.
When you go to the driver's license office to take the road test, you must provide your own vehicle. First, the license examiner checks the mechanical condition of your car. Then, the examiner gets into the car with you and asks you to drive in regular traffic. While you are driving, the examiner tests you for such things as starting, stopping, turning, backing up, and parking. If you can't control the car properly, or if you violate a traffic regulation while you are taking the test, you fail the examination. You will have to practice driving more until you take the road test again and pass it.
