Iowa Permit Practice Test

What this Iowa test asks about

Twenty questions, four topic groups: 7 on road signs, 6 on rules of the road, 5 on Iowa-specific licensing facts, and 2 on pavement markings. Each question gives four options and exactly one is correct. Signs and rules dominate the mix because they are what driving actually tests every day; the Iowa group covers the handful of numbers that differ from state to state.

The verified Iowa numbers

Every state question is anchored to a verified fact. Driver licensing in Iowa is handled by the Department of Transportation (DOT). The minimum age for a learner’s permit is 14, among the lowest in the country. Drivers under 18 must log 20 hours of supervised driving. The adult per-se blood alcohol limit is 0.08. Those four facts are the whole foundation of the Iowa questions; nothing else about the state is claimed or tested.

Taking the test

Questions come one at a time. Pick an option and you learn immediately whether it was right, with a one-line explanation of the correct answer attached. That instant correction is the point: a wrong guess becomes a learned fact within seconds. When you finish all 20, a full review shows each question, your answer, and the right one side by side. Your best score is kept in your browser, so progress is measured against your own record.
