In Iowa you can get an instruction permit at 14, an intermediate license at 16 and a full license at 17. Between those steps you need approved driver education, 30 hours of logged supervised driving and clean driving records. This guide is for Iowa teens and their parents. It sets out each stage of the graduated driver licensing (GDL) system, what the Iowa Driver’s License Manual covers, and which detailed post to read next.
Key facts (Iowa Code 2026 and Iowa DOT)
- Agency: Iowa Department of Transportation (Iowa DOT), Motor Vehicle Division. Licenses are issued at driver’s license service centers and county treasurer offices.
- Instruction permit: ages 14 to 17. You pass a vision screening and a knowledge test, but no driving test.
- Intermediate license: 16 or 17. You need the permit for 12 months, 20 supervised hours (2 at night), driver education and 6 months with no crashes or violations.
- Full license: 17. You need the intermediate license for 12 months, 10 more supervised hours (2 at night) and 12 months with no crashes or violations.
- Special minor’s restricted license (the “school license”): from 14 once you have held the permit for 6 months. It is limited to routes to school, work and farm work.
- A parent, guardian or custodian must sign a consent form each time a permit or license is issued to someone under 18.
Iowa GDL stages at a glance
| Stage | Age | What you need | Main limits |
|---|---|---|---|
| Instruction permit | 14 to 17 | Knowledge test, vision screening, parent consent | Always with a qualified supervisor in the front seat; passengers no more than seat belts |
| Special minor’s restricted license (optional) | 14 to 17 | Permit for 6 months, driver education, school certification | Most direct route to school, work or farm, up to 25 miles; one unrelated minor passenger |
| Intermediate license | 16 to 17 | Permit for 12 months, 20 hours (2 night), driver education, 6 months clean | Supervisor needed 12:30 a.m. to 5 a.m.; one unrelated minor passenger for the first 6 months unless a parent waives it |
| Full license | 17 | Intermediate license for 12 months, 10 more hours (2 night), 12 months clean | No GDL limits |
Step by step: from Iowa permit to full license
- Study the manual and pass the knowledge test. You can take it at a driver’s license service center or county treasurer office. You can also take it at home online with a parent as proctor. See the Iowa DOT permit test, including taking it at home.
- Practice with a supervisor. Until 18, a permit holder must drive with one of these people in the front seat: a licensed parent, guardian or custodian; a licensed immediate family member 21 or older; an approved driver education instructor; or a licensed person 25 or older who has written permission from a parent.
- Complete driver education. You can take an approved course at school or a licensed driving school. Parent-taught driver education is the other option. See Iowa parent-taught driver education explained.
- Log your supervised hours. You need 20 hours (2 after sunset) before the intermediate license and 10 more (2 after sunset) before the full license. See Iowa supervised driving hours and the parent log.
- Optional: get a school license. If you need to drive yourself to school or work before 16, see the Iowa minor school license explained.
- Get the intermediate license at 16. A driving test is waived after approved driver education, unless your parent, guardian or instructor asks for one. Parent-taught students must take it. See when you need an Iowa driving test and what is checked.
- Follow the intermediate rules for 12 months. See Iowa intermediate license rules for teen drivers.
- Upgrade to a full license at 17. Iowa DOT rules let eligible teens apply to upgrade electronically if their intermediate license was issued in person.
What the Iowa Driver’s License Manual covers
The English manual on the Iowa DOT site is split into five chapters. Each chapter is also available as a separate PDF.
- Your Driver’s License: who needs a license, carrying your license and insurance, and health screenings.
- Traffic Signs and Rules of the Road: signs, signals, work zones, parking and intersections.
- Preparing to Drive: vehicle maintenance, seat and mirror set-up, driver-assistance systems, seat belts, distractions, drowsy driving and Iowa 511.
- Basic Driving Skills: starting, braking, steering, lane changes, passing and defensive driving.
- Applying Your Driving Skills: intersections, highways, roundabouts, night and weather driving, sharing the road with trucks, motorcycles and bicyclists, crashes, and law enforcement stops.
The manual is also published in Spanish and French.
Iowa rules every new driver should know
Phones and electronic devices
Under Iowa Code section 321.276, no driver may hold, view or manipulate an electronic device while driving. Hands-free or voice-activated use is allowed. Video calls, video streaming and reading messages are not. The warning-only period ended on January 1, 2026, so officers now issue citations, and a violation counts as a moving violation. The same rule now covers teen drivers: the separate under-18 phone ban in section 321.180B was repealed in 2025. Some copies of the July 2026 manual still say permit, intermediate and school license holders may not make or take calls unless stopped off the road, so the safest habit for a new driver is no calls at all. For other states, see hands-free and texting laws for US drivers.
Alcohol and drugs
- Iowa’s operating while intoxicated (OWI) limit is 0.08 alcohol concentration. Any amount of a controlled substance in your blood or urine is also OWI.
- Drivers under 21 lose their license at 0.02 or more (Iowa Code section 321J.2A): at least 60 days, or at least 180 days at 0.08 or more.
- Even without a criminal conviction, operating while intoxicated means at least a 180-day revocation. Refusing a test means a one-year revocation and a fine of at least $1,250.
- A first OWI offense carries at least 48 hours in jail and a $1,250 fine under Iowa Code section 321J.2.
- An open container of alcohol, or a beverage containing THC, is not allowed in the passenger area. That area includes the glove compartment. The fine can be up to $200 for the driver and for each passenger.
Background: zero tolerance laws for drivers under 21, implied consent and DUI and drugged driving and cannabis.
Iowa numbers from the manual
- Carry with you: your license or permit, current registration and an insurance card (printed or electronic).
- Speed limits where none is posted: 20 mph in a business district, 25 mph in a residential or school district, 45 mph in a suburban district, 60 mph on primary roads and urban interstates, 70 mph on rural interstates. The interstate minimum is 40 mph.
- Signals: at least 100 feet before a turn where the limit is 45 mph or less, and at least 300 feet where it is higher.
- Parking: within 18 inches of the curb. Not within 5 feet of a hydrant, 10 feet of a stop sign, 20 feet of a fire station entrance or 50 feet of a railroad crossing, and not on a bridge outside city limits.
- School buses: on a road of three lanes or fewer, traffic in both directions stops. On four or more lanes, only traffic behind the bus stops. Stop at least 15 feet from the bus, and slow to 20 mph or less when you see amber lights. Passing illegally can cost your license for up to 180 days.
- Move Over or Slow Down: change lanes for any stopped emergency, tow, maintenance, construction or garbage and recycling vehicle with flashing lights, or slow down and be ready to stop if you cannot. Breaking it can mean a suspension of up to one year.
- Emergency vehicles: stay at least 500 feet behind one using lights and siren.
- Steer It, Clear It: after a crash with no injuries, move a drivable car out of the traffic lanes. Report a crash with injury, death or more than $1,500 of damage to police; failing to report within 72 hours costs your license.
- Passing: not within 100 feet of an intersection, a railroad crossing or a signed narrow bridge, viaduct or tunnel.
- Headlights: on from sunset to sunrise and whenever you cannot see 500 feet ahead.
- Seat belts: a primary offense, with fines up to $50 per passenger and $100 per passenger under 18.
- Pedestrians: since 2024 you must yield to pedestrians on foot and to anyone using a human-powered device (a pedestrian conveyance).
- Slow-moving vehicles: a reflective orange triangle means the vehicle travels at 35 mph or less.
- Window tint: the windshield and front side windows must let through at least 70 percent of light, with no medical exemption.
- Hot cars: Iowa law lets you break a window to help a person or animal trapped inside.
Crashes and violations during GDL
A moving violation or crash while you hold a permit or intermediate license can lead to remedial driver improvement action or suspension. It also restarts the clean-record clock before your next stage: 6 months for the intermediate license and 12 months for the full license.
General US topics in the Iowa manual
These chapters follow national standards. Our national guides cover them in detail:
- Signs and markings: US road signs by shape and color, US pavement markings, traffic signals
- Right of way: four-way stops, roundabouts, pedestrians and crosswalks, right on red
- School buses and trains: school bus stopping laws, railroad crossings
- Emergency vehicles: move over laws, pulling over for emergency vehicles
- Sharing the road and conditions: trucks, motorcycles and bicycles, snow, fog and rain, freeway driving
- After a crash: what to do after a car accident

Moving to Iowa as a teen driver
For licensing, you count as an Iowa resident once you have lived in Iowa for 30 days in a row, taken a permanent job here, enrolled a child in an Iowa public school, registered to vote, claimed a homestead or military property tax exemption, or receive Iowa public assistance. Visitors and students can drive on a current license from home.
A 16 or 17 year old Iowa resident who drove for at least a year as a resident of another state can get a Class C license without Iowa driver education. Up to 6 months of that year can be on a permit. You must live with a parent or guardian, have no moving violations on your record, and pass the written and driving tests. General advice: transferring your license to another state.
Common questions
How old do you have to be to drive in Iowa?
You can get an instruction permit at 14 and drive with a qualified supervisor. Unsupervised driving starts with the special minor’s restricted license, from 14 after 6 months on a permit, or the intermediate license at 16.
Do I need driver’s ed to get a license in Iowa?
Yes, if you are under 18. The intermediate license requires an approved driver education course or approved parent-taught driver education.
How long is an Iowa instruction permit valid?
Up to four years from your birthday in the year it was issued.
Can I carry friends on an Iowa permit?
Only as many passengers as there are seat belts, and only with your qualified supervisor in the front seat.
When can I drive alone at night in Iowa?
With an intermediate license you can drive alone from 5 a.m. to 12:30 a.m. Between 12:30 a.m. and 5 a.m. you need a qualified supervisor, unless you carry a waiver for school activities or work. A full license has no hour limits.
How much does an Iowa instruction permit cost?
Iowa Code section 321.191 sets the instruction permit fee at $6 and a Class C license at $4 per year of validity (Iowa Code 2026). Check the current figure with Iowa DOT before you visit.
