Yes, you can drive at night with a learner’s permit in Iowa. There’s no curfew at the permit stage. What you can’t do is ignore the night hour requirement: Iowa wants 2 supervised night hours before you move to the next stage. Two. That’s the lowest mandatory night requirement of any state in the country.

Iowa also has a two-stage system that trips people up. More on that below.

When Does “Night” Start in Iowa?

Iowa ties night to the sun, not a clock. Night begins at sunset and ends at sunrise. That means the window shifts every day and varies a lot by season.

In Des Moines, sunset lands around 4:30 PM in December. By late June it’s 8:50 PM. That’s a four-hour-plus swing depending on the time of year. A drive at 7 PM in January counts as night. The same drive in July does not.

If you’re keeping a paper log, you’d need to look up the actual sunset time for your town before every session. Most families don’t bother. They guess wrong and end up with night hours that don’t count.

Iowa’s Curfew Rules

Iowa has no curfew for permit holders. You can drive at any hour with a qualified supervisor in the car. Anytime after sunset is fair game for your night hours.

The curfew restrictions in Iowa apply to intermediate license holders (ages 16-17), not permit holders. Once your teen has the intermediate license, driving between midnight and 5 AM is restricted. But at the permit stage? No restriction.

Iowa’s Two-Stage System

This is where Iowa gets unusual. Most states have one supervised-hours requirement. Iowa splits it into two:

Instruction permit stage: 10 total supervised hours, including 2 at night. This is what you complete before your first road test.

Intermediate license stage: After passing the test and getting the provisional license, Iowa requires 10 more supervised hours, including 2 more at night, before the teen can move to a full license.

So the 20-hour and 4-night-hour figures you’ll see cited online aren’t a single block. They span two separate stages. If your teen is 14 and just got their permit, they’re working on the first 10 hours.

The permit age of 14 also means this: even if a teen gets their permit the day they turn 14, they can’t get the intermediate license until 15 (due to the 12-month hold period). So nobody’s rushing through this.

Getting Your 2 Night Hours Done

With only 2 required night hours at the permit stage, this isn’t hard. Even in summer, two late-evening drives after 9 PM covers it. In winter, it’s even easier. Sunset at 4:30 PM means a quick run to the grocery store qualifies.

A few things that actually help:

Don’t save them for last. Night driving takes some adjustment. Better to practice it early when there’s no deadline pressure, not the week before the road test.
Short drives count. A 20-minute drive is 20 minutes. You don’t need a 90-minute session to knock out a night hour.
Iowa winters are your friend. December and January sunsets before 5 PM mean almost any after-school drive counts as night. Get this done in winter if you can.

Practical Tips

Know your sunset time. In Ames at the start of November, sunset is around 6:05 PM. By mid-December it’s 4:35 PM. That 30-minute post-dinner drive your teen takes varies in whether it counts, and you want to know before you drive, not after.

Avoid treating the 2-hour minimum as the goal. Two hours is the floor. More night driving before the test means a more confident driver after it. The state won’t stop you from logging extra hours.

Keep the log accurate. Iowa’s DMV expects a driving log at the road test. Drives logged as night that technically started before sunset can cause problems at the road test.

Moda tracks sunset and sunrise using your phone’s GPS and tags each session correctly. Your night hours are accurate without looking anything up.
