제 1 장: 운전 면허증

Understanding the rules for obtaining and maintaining a driver’s license is the first step toward becoming a safe and legal driver in Montana. This knowledge is essential for passing the written knowledge test, as it covers the types of licenses available, the requirements for each, and the state’s system for tracking driving performance. Mastering this information ensures a driver starts their journey on the right side of the law and with a clear understanding of their responsibilities.

A Montana driver’s license is a privilege, not a right. It signifies that a driver has demonstrated the minimum knowledge and skill required to operate a motor vehicle safely. The state issues different types of licenses and permits based on the driver’s age, experience, and the type of vehicle they intend to operate.
