How Many Questions Are on the Iowa Permit Test?
Iowa's instruction permit knowledge test has 35 multiple-choice questions, covering traffic laws, road signs, and safe driving practices from the Iowa Driver's Manual.
A starting age most states don't match
An Iowa teen can apply for an instruction permit at just 14, with parent or guardian consent — one of the youngest starting ages of any state.
A separate Special Minor's Restricted License is even available at 14½, letting a teen drive unsupervised to school, work, or farm-related tasks within 25 miles, well before the standard licensing timeline finishes.
A longer permit hold than most states use
Iowa requires holding the instruction permit for a full 12 months — longer than most states' 6-month standard — before an intermediate license at 16, though the supervised-hours requirement itself is a comparatively modest 20 hours.
Our free Iowa permit practice tests cover the same topic areas the official exam draws from, including a dedicated set of sign-recognition questions.
How our practice tests are structured
dmvwrittenexam.com splits its 145 original Iowa permit questions into multiple 25-question practice tests, giving far more repetitions than the official 35-question test alone would.
Each question includes an explanation and a source reference, so you learn why an answer is correct instead of just memorizing a letter.
