View All PlansWelcome to our Iowa DOT Written Test Study Guide practice test, an intuitive tool designed to help you become a better driver. Use it during your learning phase to learn and master the various aspects of driving theory described in the official Iowa Driver’s License Manual (Iowa DMV Handbook (IA Driver's Manual) 2025). All 20 questions have multiple answer choices, but only one is correct. Complete each practice session at your own pace, as there is no timer to pressure you. Read every question twice and think before you select an answer. Develop this habit now and you’ll avoid making avoidable mistakes at the DOT office on exam day.
If you get stuck on a difficult question, you can request a hint from our automated assistant. Initiate a conversation during an active practice session and request personalized help. This AI coach can also provide real-life examples and additional explanations that help you understand the reasoning behind each correct answer. Students with auditory memory can benefit from using the voice-over function. Once activated, an artificial voice will read the questions and answer choices aloud. Use this feature and enable ambient music from the “Test settings” menu to increase your focus in busy environments where distractions are more common.
Whether waiting in line at the grocery store, commuting to work, or beginning an extended study session at home, you can use this practice test anytime, anywhere in the world. With unlimited attempts and nonstop access, there are no limits to how often you can study with this tool. For best results, we recommend developing and consistently following a study routine consisting of this practice test and the official Iowa DOT Driver’s License Manual.
Becoming a safe and responsible driver in Iowa takes time and effort. Even the most professional drivers were once beginners without behind-the-wheel experience. As they did, you’re beginning a long but rewarding journey. Avoid rushing during your learning phase, as this is when you build the foundation of a lifelong skill.
