Iowa Permit Test Practice 2026
Permit testing in Iowa starts with a written exam - signs, signals, right of way, plus Iowa-specific items from the handbook. Below: 6 sample questions in the real format and an Iowa cheat sheet. DMV Ready has the rest.
What’s on the Iowa permit test?
Plan on 35 questions for the Iowa permit test, with a 80% pass mark (around 28 correct). Questions come from the Iowa handbook and cover the standard categories - signs, signals, right of way, speed, alcohol - alongside an Iowa-specific section that catches people who studied with generic prep. Iowa runs testing through the Iowa DOT; rural-road and farm-equipment questions show up more than in coastal states.
Expect mostly recall questions: sign meanings, who goes first at a 4-way stop, what limits apply where. A handful of scenario questions test how you’d actually respond on the road.
If you study generic DMV practice, you’ll be missing the Iowa-specific section the test draws from. The handbook has rules unique to Iowa; practicing on Iowa-specific questions is the fix.

- One headlight in the center of the vehicle
- At least one headlight, placement doesn’t matter
- Two headlights: one on the right and one on the left

Question 6: What does the Emergency Notification System (ENS) sign provide at railroad crossings?
- A phone number and crossing ID for emergencies
- Speed limit for the crossing
- Train schedule information
Correct answer: A phone number and crossing ID for emergencies
Why: The Emergency Notification System (ENS) sign at railroad crossings provides a phone number to call and a unique crossing ID number to report to the dispatcher if a vehicle is stuck or stalls on the tracks, or if there is another emergency at the crossing. This information helps railroad authorities quickly identify the exact crossing location and respond appropriately.
💡 Memory tip: Blue ENS sign: phone number + crossing ID for emergencies.
