FREE Iowa DMV Practice Test #14 Page 5 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.
Each question on the practise exam has a tip and explanation to help you recall the ideas. Questions about traffic rules, traffic signs, and driving statutes, as well as information from the Driver Handbook, will be included in the written portion of the official Iowa DMV test.
You must properly answer 28 of the 35 questions to receive a passing mark. To help you prepare for your Iowa instruction permit or driver's licence, take our DMV practise test.
The DMV exam is offered in a variety of languages.
Using any form of testing help will result in an automatic fail, and the DMV may take further action against your driver's licence, so avoid it.

Drivers of trucks, buses, vans, and any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.
