Iowa Instruction Permit

By Javier Marín, Editor·Last reviewed September 2026·How we check this

Iowa's instruction permit is one of the youngest-starting in the country. A teen aged 14 or older who passes the knowledge test and a vision screening can begin practice driving with a licensed adult in the front passenger seat. The permit must be held for at least 6 months before a teen can apply for an intermediate license, and Iowa requires a documented log of supervised practice hours.

Eligibility

To qualify for an Iowa instruction permit, the applicant must:

Be at least 14 years old.
Have written consent from a parent or legal guardian.
Pass a vision screening at the Iowa DOT office.
Pass the Iowa knowledge test.
Provide proof of identity, Social Security number, and Iowa residency.
Be enrolled in school and not in violation of Iowa's school-attendance laws.

Documents to bring

Iowa REAL ID-compliant identity documents are required at the first DOT visit:

One proof of identity — certified U.S. birth certificate or unexpired U.S. passport.
Proof of Social Security number — SS card, W-2, or pay stub showing the full SSN.
Two proofs of Iowa residency — utility bill, school enrollment letter, parent's mortgage statement, or lease.
Form 411007, signed by both the applicant and a parent or legal guardian.
The permit fee — currently $6 for a 1-year permit (renewable as needed).

Knowledge test

The Iowa permit knowledge test has 35 multiple-choice questions covering speed limits, right-of-way, signs, signals, lane markings, school zones, and the basics of Iowa impaired-driving law. You need to answer at least 28 correctly (80%) to pass. Failed attempts may be retaken — typically the next day at busy offices, sometimes the same day at smaller stations. The Iowa Driver's Manual is the only study source the agency endorses; many third-party practice tests are based on outdated versions.

Supervised driving requirements

Once the permit is in hand, the teen must complete:

20 hours of supervised driving (or more if recommended by an Iowa-approved driver education course).
At least 2 of those hours at night.
A signed parent or guardian log certifying the practice hours.

Iowa's 20-hour requirement is one of the lower thresholds among states that require any logged practice. The supervising adult must be at least 21 years old, hold a valid driver's license, and sit in the front passenger seat with access to the controls if needed. A licensed driver-education instructor counts as a supervisor during course practice sessions.

Driver education

Iowa requires applicants under 18 to complete an approved driver education course before applying for an intermediate license. Course options include:

Public-school driver education — offered through many Iowa school districts.
Commercial driving schools — private courses authorized by the Iowa DOT.
Parent-taught driver education — Iowa allows certain parents and guardians to provide the in-vehicle instruction component, with the classroom portion completed online.

Permit restrictions

Throughout the Iowa permit period:

The permit holder may drive only when supervised by a licensed adult described above.
No drugs or alcohol — Iowa's zero-tolerance law applies to permit holders the same as to intermediate drivers.
Hand-held cell phones are prohibited; hands-free is allowed only for adults supervising the permit holder.
All occupants must wear seat belts.

Iowa does not impose a midnight curfew on permit holders, since the permit already requires supervision at all times. However, building practice in night and adverse conditions is critical for both the 2-hour night requirement and for safe driving once the teen is on their own.

Validity and renewal

The Iowa instruction permit is valid for 1 year and can be renewed for additional 1-year periods until the teen is ready to apply for an intermediate license. A teen who turns 16 partway through the permit period and has met the 6-month and 20-hour thresholds can apply for the intermediate license without waiting for the permit to expire.
