What is the youngest age you can get an Iowa instruction permit?
20 practice questions in the style of the knowledge test.
How close is this Iowa DMV practice test to the real one?
The style is close: multiple choice on Iowa traffic laws and road signs, from the manual the DOT names as the study guide. The length may not be. The DOT doesn’t publish how many questions the real test has or its pass mark, and these aren’t its questions.
The DOT’s own practice test draws 25 questions from its pool, some of them from the real test, so take it as well. The where-to-learn page explains how it works and has a study plan for the manual.
