Chapter 1: Your License to Drive

Understanding the rules for obtaining and maintaining a driver’s license is the first step toward becoming a safe and legal driver. This knowledge is essential not only for passing the written exam but also for navigating the responsibilities that come with the privilege of driving. Mastering these regulations ensures a driver is properly licensed for the vehicle they operate and is aware of the state’s programs for new drivers, such as the Graduated Driver License system.
