Study by Category

Master each topic before your Iowa written test. 4 categories are free to start.

Shape and color carry the meaning before you can read the words: an octagon is always stop, a yellow diamond always warns. Covers regulatory, warning, guide and work-zone signs, including the ones with no text at all.

Speed limits, parking and the everyday rules that carry points when broken. Covers the basic speed law, why a posted limit is a maximum rather than a target, and where you may never stop or park.

Signals, flashing lights, and the arrows that override them. Covers what a yellow light actually requires of you, when a red arrow forbids a turn a red ball would allow, and who has control when the lights go dark.

The paperwork side of driving legally. Covers licensing and insurance requirements, what to carry in the vehicle, and the steps to take after a collision.

About the Iowa DMV Test

Iowa's written knowledge test is administered by the Iowa Department of Transportation (Iowa DOT) and is required for anyone applying for a learner's permit or first driver's license. The test has 35 multiple-choice questions drawn from the Iowa Driver's Manual, and you need at least 28 correct answers (80%) to pass.

Where and How to Take It

In-person at Iowa DOT service center, at participating schools, or at home through the Skip the Trip program. Walk-ins are generally accepted, though booking ahead can shorten your wait. The written test is available in 21 languages, including English, Albanian, Arabic, Bosnian. Iowa offers the 'Skip the Trip' program - students can take the knowledge test at participating schools or at home with a parent administering.

What to Bring

Plan to bring the documents the Iowa DOT requires: Proof of identity (birth certificate or passport); Social Security number; Proof of Iowa residency; Parental consent (if under 18). The knowledge test is part of a permit fee of about $8.

On Test Day

Results are immediate at DOT offices. Skip the Trip home tests take 7 to 14 days to process.

If You Don't Pass

Iowa publishes no set waiting period, attempt limit, or retest fee for the non-commercial knowledge or driving test: if you fail, you may repeat the test at the examiner's discretion. CDL differs: a failed CDL knowledge or skills test cannot be repeated the same day, and the $25 skills-test segment fees apply again to a new appointment. A six-month lockout after 3 unsuccessful attempts exists in Iowa's rules, but it applies only to someone contesting a suspension or denial for incapability, not to ordinary applicants.

Minimum Age and Eligibility

You must be at least 14 years old to take the Iowa knowledge test. Applicants under 18 must complete approved driver education, hold the instruction permit for 12 months, and complete 20 hours supervised driving (2 at night) before intermediate license.

After You Pass

An instruction permit allows supervised driving with a licensed driver 21+ (or parent/guardian/instructor) in the front seat. You must hold for 12 months. Intermediate license at 16 with restrictions until age 17.
