View All PlansIdaho has some of the most scenic routes in the United States. The 31.4-mile-long Ponderosa Pine Scenic Byway runs from Boise to Stanley, providing drivers with breathtaking views of the Sawtooth Mountains and the Boise River. While the views are stunning, it is crucial to keep your focus on the road. There are plenty of viewpoints where you can pull over and safely admire the view without putting your life in danger. Safe driving always comes first, and this principle is heavily emphasized in the official Idaho Driver’s Handbook (Idaho DMV Handbook (ID Driver's Manual) 2025).
As you begin your learning phase, you should use the most efficient tools to learn driving theory. The official Idaho driver’s manual discusses this subject in detail, but not everyone is satisfied with traditional study methods. Our Idaho DMV Written Test Study Guide practice test has been designed to help you master driving theory through active learning. Each of the 20 questions has multiple answer choices, but only one is correct. Use this intuitive tool to improve your knowledge and build the confidence to pass the official written knowledge test on your first attempt.
With unlimited attempts, you can restart the test as often as you like. Do not let a poor practice session discourage you. Everyone makes mistakes, and we allow you to learn from them. Use the “Restart test” button to wipe your current progress and begin a new session. We recommend occasionally checking your personal Challenge Bank™ to identify areas that need improvement and learn from your mistakes. This section includes detailed explanations for all the questions you got wrong during your previous practice sessions. Questions in the Challenge Bank will remain there until you answer them correctly.
The roads of Idaho are yours to explore, but you must do so responsibly and safely. Take your time and study driving theory before you improve your driving skills from behind the wheel of your favorite vehicle. During this time, you can use our Idaho DMV Written Test Study Guide practice test alongside the official driver’s manual to master this subject.
