Iowa Permit Driving Hours: 20 Required, 2 at Night, Log Before Upgrade

Teens under 18 must complete 20 hours of supervised driving, including at least 2 hours at night, before applying for an intermediate license. Adults 18+ skip mandatory logging entirely.

Iowa's 20-Hour Supervised Driving Requirement Before Upgrade

Iowa's Graduated Driver's License (GDL) system requires specific practice time with a permit. The total hours needed depend on your age.

• Under 18: Complete 20 hours of supervised driving (minimum 2 at night) after driver's education before getting an intermediate license. Then log 10 additional hours (minimum 2 at night) before applying for a full license.
• 18 and Older: No mandatory log or minimum practice hours. Take the driving skills test after passing the knowledge exam.

These are separate requirements. Iowa's GDL progression requires 20 supervised driving hours, including at least 2 after sunset. Parent-Taught Driver Education requires 30 hours of street or highway driving, including 3 at night. Iowa DOT says 20 of the Parent-Taught hours can count toward the GDL supervised-driving requirement.

When Do the Additional 10 Supervised Hours for an Iowa Full License Start?

They start after the intermediate license is issued. Iowa requires 20 supervised hours, including two between sunset and sunrise, before the intermediate license. Then the driver completes another 10 supervised hours, including two at night, while holding the intermediate license before moving to a full license. Iowa DOT full-license requirements.

What Counts as Valid Supervised Driving Time in Iowa?

Not all driving time qualifies for your log. Here's what counts toward the required practice hours in Iowa.

• Driver's Ed Behind-the-Wheel Hours: Yes, time you drive with your instructor during an approved Driver's Education course counts toward your 20-hour total for the instruction permit phase.
• Supervised Driving: Any driving with a licensed adult who is at least 25, or an immediate family member at least 21.
• What Doesn't Count: Driving alone, driving with a supervisor under 21 (unless immediate family), and hours from your permit phase cannot be 'double-dipped' to count toward the 10 hours needed for your full license.

Review full rules in the Iowa Driver's Manual PDF before starting your supervised practice.

What Counts as Nighttime Driving for Iowa Permit Practice Hours?

Iowa DOT uses driving between sunset and sunrise for required nighttime hours. That applies to the two nighttime hours needed before an intermediate license and the two additional nighttime hours required while holding the intermediate license before a full license. Iowa DOT supervised driving guidance.

Logging and Verifying Iowa Supervised Driving Hours

You have two options for tracking your supervised driving hours. The Iowa DOT does check your submitted log.

Logging Methods

• Official App (Recommended): The RoadReady app tracks drives via GPS, auto-calculates night/day hours, and creates a printable PDF log. Check the parent-taught driver education page for app setup instructions.
• Paper Log: Use a detailed log sheet or the official Form 431228 for Parent-Taught Driver Education. Record date, duration, conditions, and supervisor for every drive.

Who Signs or Certifies an Iowa Supervised-Driving Log?

For the regular GDL path, Iowa DOT places responsibility on the parent or guardian to make sure the required supervised hours are completed. Keep a clear log that the parent or guardian can verify. Parent-Taught Driver Education has its own formal driving-log requirements and submission process.

What if You Use More Than One Supervising Driver for Iowa Practice Hours?

You may build supervised driving experience with different adults as long as each person qualifies under Iowa's supervision rules. Record each session clearly so the total hours and nighttime hours can be verified later.

How Iowa Confirms Supervised Driving Hours

For the regular GDL path, Iowa requires the supervised-driving hours, but the log in Iowa DOT's Parent's Supervised Driving Program is a tracking tool for families rather than a separate document listed as mandatory at the intermediate-license appointment. A parent or guardian provides the required written consent when the teen upgrades.

Parent-Taught Driver Education is different: its 30-hour driving log is a formal course requirement, and Iowa DOT identifies Form 431228 for that program.

Keeping Iowa Supervised Driving Records Clear

Track each drive accurately so your family can confirm the required total and nighttime hours. Do not mix the regular 20-hour GDL requirement with the Parent-Taught Driver Education 30-hour log.
