FREE Iowa DMV Practice Test #13 Page 3 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.

18 . When you are behind a motorcycle, you should:
When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.
19 . A driver can legally pass on the right side of another vehicle:
If there is an available passing lane, you may pass on the right of a vehicle or bicycle that is turning left or waiting to turn left. It is also legal to pass on the right when driving on a multilane road with two or more lanes traveling in the same direction. You may never drive off the pavement or main-traveled portion of the road to pass another vehicle.
20 . A blood alcohol concentration of 0.02 percent:
Every 0.02 percent increase in blood alcohol concentration nearly doubles a driver's risk of being in a fatal crash.
