FREE Iowa DMV Practice Test #21 Page 4 of 5
The DMV practise tests in Iowa have been updated for January 2025. It comprises questions based on the most important traffic signals and legislation for 2025 from the Iowa Driver Handbook. To study for the DMV driving permit test and driver's licence exam, use actual questions that are very similar (often identical!) to the DMV driving permit test and driver's licence exam.
