Sample Iowa Permit Test Questions
Three of the Iowa-specific questions from our bank, with the answer and the rule behind it. The Iowa bank behind the tests above holds 198 unique questions.
1. The maximum speed limit on Iowa's rural interstate highways is:
- A. 70 mph (correct)
- B. 65 mph
- C. 75 mph
- D. 80 mph
Why: Iowa's maximum speed limit is 70 mph on rural interstate highways. Urban interstates have lower limits, and you must always obey a lower posted limit.
2. Under Iowa's hands-free law, while driving you may not:
- A. Hold, type, scroll, or enter GPS by hand (correct)
- B. Use voice commands to place a phone call
- C. Keep your phone in a dashboard mount
- D. Listen to the radio or a podcast
Why: Iowa's hands-free law prohibits holding a phone, typing, scrolling, entering GPS, streaming, or calling unless the device is used hands-free.
3. In Iowa, a driver under 21 will have their license revoked at a BAC of:
- A. 0.02 or more (correct)
- B. 0.05 or more
- C. 0.08 or more
- D. 0.10 or more
Why: Iowa's zero-tolerance law revokes the license of a driver under 21 who operates with a BAC of 0.02 or more.
Iowa Permit Test Study Guide (2026)
A free Iowa DOT written test study guide - updated for 2026, verified against the official Department of Transportation handbook.
Reviewed by Chad HenryAfter 25 years of teaching driver educationLast reviewed September 2026
Iowa drivers share two-lane highways with farm equipment and face true Midwestern winters around Des Moines, Cedar Rapids, and the small towns between, so the DOT knowledge test emphasizes road signs, safe passing, and winter technique. Based on the official Iowa Driver's Manual, our Iowa practice permit test prepares you for exactly what the DOT will ask.
What to Expect on the Iowa Permit Test
The Department of Transportation (DOT) requires every new driver to pass a written knowledge test before being issued a learner's permit. The DOT does not publish the number of questions; to pass you need a pass mark the DOT does not publish (our practice tests use 80%). You must be at least 14 years old to apply. Every question is drawn from the official Iowa driver's handbook, so the topics on our practice tests match exactly what the DOT asks.
Topics Covered on the IA Written Test
- Traffic Laws (Rules of the Road): State-specific rules of the road, including right-of-way, lane changing, and intersection rules
- Road Signs: Recognition and meaning of all standard road signs - warning, regulatory, and informational
- Speed Limits: Default speed limits, school zones, work zones, and highway speeds
- Safe Driving: Following distance, blind spots, defensive driving, and weather conditions
- Alcohol & Drugs: DUI laws, BAC limits, and consequences of impaired driving
- Parking Rules: Legal and illegal parking situations, curb colors, and distances
How to Prepare for the Iowa Permit Test
The strongest preparation pairs a read-through of the official Iowa Driver's Handbook with repeated practice tests that surface your weak spots. The DOT writes its test from that handbook, so the rules you practise here are the rules you will be asked about. A sensible target: score at least 80% on several fresh practice tests in a row - and read the explanation on every miss - before you book your appointment.
