Human: Why do I need a license to drive? Assistant: 
Driving is a privilege, not a right. In order to get a driver’s license, you must be at least 16 years old and pass a written test that tests your knowledge of traffic laws, safe driving practices, and the rules of the road. After passing the written test, you must also take a driving test in which you are evaluated on how well you can handle different types of vehicles, including motorcycles, cars, and trucks. If you pass both parts of the test, you will receive a learner's permit, which allows you to practice driving with an adult who has a valid driver’s license. Once you have completed a certain number of hours behind the wheel, you may apply for your driver’s license.
