How to Get Your Iowa Learner's Permit (Iowa DOT Guide)
Everything you need to apply for a Instruction Permit through the Iowa Department of Transportation, Motor Vehicle Division (Iowa DOT) — the age requirement, documents to bring, the knowledge test, fees, and what comes next.
Requirements & minimum age
To get a Instruction Permit in Iowa, you must be at least 14 and apply in person at the Iowa Department of Transportation, Motor Vehicle Division (Iowa DOT). Applicants under 18 generally need a parent or guardian to sign, and many states also require enrollment in or completion of a driver-education course.
Iowa's DOT knowledge test covers traffic laws, road signs, and safe driving — including rural and farm-equipment safety — from the Iowa Driver's Manual. Teens complete supervised practice and intermediate-license restrictions under graduated licensing.
Documents to bring to the Iowa DOT
Bring original or certified documents (not photocopies) that establish:
- Proof of identity, such as a certified U.S. birth certificate or valid U.S. passport
- Proof of Social Security number, such as a Social Security card or a W-2 form showing your full SSN
- Proof of Iowa residency, such as a school enrollment record or a piece of mail addressed to you at your home
- Written parental or guardian consent for applicants under 18, given in person or on the Parent's/Guardian's Written Consent Form (Form 430018)
The knowledge test
In Iowa, the knowledge test can be taken online (as well as in person). A 35-question multiple-choice knowledge exam requiring 28 correct answers to pass, plus a vision screening; eligible teens may take the knowledge portion online at home through the Skip the Trip program or at a participating school, otherwise it is taken at a service center or county treasurer office.

The Iowa DOT charges $6 (valid for 4 years); a $10 out-of-county fee may apply at some treasurer offices for the permit. Amounts can change and sometimes include separate knowledge-test or service fees, so verify the current cost with the Iowa DOT before you visit.
What happens after you pass (graduated licensing)
Iowa uses a three-stage graduated driver's license system for drivers under 18: an instruction permit at age 14, followed by an intermediate license at 16 and a full license at 17. Teens who complete driver education and hold a permit for six months with a clean record may qualify at age 14 and a half for a minor school license, which allows limited unsupervised driving to and from school.
