Iowa DOT Fines and Limits Permit Practice Test 2025

You’re studying to pass your Iowa knowledge test for an instruction permit (which is required if you’re under 18) so you can practice driving for a driver’s license. Think how it would feel to lose your driving privileges after all the effort it’s taken you to get them! This free Iowa Fines and Limits permit practice test will help prevent that as well as help you pass your knowledge test.

This specially designed 40-question practice test is about the consequences of violating Iowa’s traffic laws or other laws that may affect your license. It’s up to date as of October 2025. It’s based on Iowa’s official driver’s manual (Iowa DMV Handbook (IA Driver's Manual) 2025) and the Iowa Code. And like the other Iowa permit practice tests we offer, each question on this Fines and Limits permit practice test comes with an optional hint and an explanation of the correct answer, courtesy of our automated assistant.

On this practice test, you’ll learn which offenses will cause mandatory revocation of your driver’s license. You’ll learn about potential penalties for operating a vehicle while intoxicated (OWI), refusing a test of your blood alcohol concentration (BAC), leaving the scene of an accident (hit and run), and driving even though your license is suspended or revoked. You’ll learn about some non-driving-related offenses that can lead to license suspension. You’ll also learn what you must do to get your license back after it has been suspended. You’ll learn what Iowa law says about the use of seatbelts in vehicles. Finally, you’ll also learn some of the rules of Iowa’s Graduated Driver’s License (GDL) system.

In the United States, about 37 people die in alcohol-related crashes every day. That works out to about one fatality every 39 minutes. About 28 percent of all traffic deaths involve alcohol-impaired drivers. In 2022, there were 5.93 million traffic crashes. 13,524 people died in traffic crashes in which alcohol consumption was a contributing factor.

In Iowa in 2022, there were 53,706 total traffic crashes, involving 91,475 vehicles and 91,493 drivers. 13,213 (14.4%) of the drivers were under 21 years of age. 22,447 drivers were formally charged with some offense. 2,236 drivers were under the influence of alcohol. 250 drivers were under the influence of drugs or medications. There were 336 traffic deaths.

Violating Iowa’s traffic laws invites administrative penalties (fines or loss of license) and criminal penalties (fines or jail time, and a criminal record). It also risks a serious accident. Learn what can happen so you can pass the official knowledge test and stay out of trouble whenever you’re on the road.
