By the end of this topic you can

• You can name the three main GDL steps and the age for each one.
• You can explain what the optional special minor's restricted license allows.
• You can say how long you must hold each step before moving up.
• You can explain why a ticket or crash delays your next step.
• You can list the supervised driving hours needed for each upgrade.

What you need to know and understand

• The instruction permit is available from age 14 after passing the knowledge test and vision screening.
• The special minor's restricted license is optional and available from age 14 and a half.
• The intermediate license is available at 16 after holding a permit for 12 months.
• You need 20 hours of supervised driving, 2 of them at night, to get an intermediate license.
• The full license is available at 17 after holding the intermediate license for 12 months with a clean record.
• You need 10 more supervised hours, 2 at night, during the intermediate stage.
• Parent or guardian consent is needed every time a permit or license is issued under 18.

The Iowa ladder from 14 to 17

1. Instruction permit (age 14 or older): pass the knowledge test and vision screening and bring parent consent. You may drive only with a qualifying supervising adult beside you.
2. Special minor's restricted license (optional, age 14 and a half or older): complete driver education and hold a permit with a clean record for six months. It allows limited solo driving to school, school activities and work.
3. Intermediate license (age 16 or older): hold a permit for a total of 12 months, finish driver education, log 20 supervised hours with 2 at night and stay crash and violation free for the last six months.
4. Full license (age 17 or older): hold the intermediate license for 12 months, log 10 more supervised hours with 2 at night and keep a clean record for the 12 months before you apply.

Why clean driving matters at every step

Iowa ties each upgrade to a clean record. On a permit, every moving conviction, at-fault crash or broken restriction pushes your intermediate license back by six months, according to Iowa DOT. On an intermediate license, each one delays your full license by 12 months. A first offense usually brings a warning letter and a possible suspension, and a second offense brings a 30-day suspension.

The school license is stricter still: each ticket, crash or broken restriction on it means a three-month suspension, a reinstatement fee and a later start on your intermediate license.

Restrictions that follow you up the ladder

Our deeper guides to learning to drive in Iowa and to the intermediate license rules go through each stage in more detail.

• No more passengers than there are seat belts, on every teen license.
• Intermediate drivers may not drive alone between 12:30 a.m. and 5 a.m. unless a parent signs a waiver for school activities or work.
• For the first six months of an intermediate license, a passenger limit of one unrelated minor applies unless a parent waives it when the license is issued.
• A full license issued before 18 or 21 is marked 'under eighteen' or 'under twenty-one'.

Common mistakes

• Thinking the school license is required. It is optional, and many teens go straight from permit to intermediate license.
• Forgetting the night hours. Both the 20-hour and the 10-hour logs need at least 2 hours between sunset and sunrise.
• Assuming a minor ticket will not matter. Any moving conviction resets the clean-record clock and delays your next step.
