Supervised Driving Hours Calculator

Road44, the driving log app mentioned below, is our app. State figures were checked on state licensing-agency sites in September 2026. Requirements vary and change, so check your state's licensing agency for the numbers that apply to you. This calculator covers US learner permits.

How the calculator works out your hours left

Most states set one number for supervised practice and put a night minimum inside it. California asks for "50 hours, including 10 hours of night driving." That's 50 hours in all, not 60. Every state we checked words it the same way, so the calculator counts night hours as part of the total.

From your four numbers it works out three results:

• Night hours left: the required night hours minus the night hours you've logged.
• Total hours left: the required total minus your logged total, but never less than the night hours you still owe.
• Day hours left: total hours left minus night hours left. You can drive these at any time of day.

The "never less than" part matters once the total is covered. Say your state asks for 50 hours, 10 of them at night, and you've logged 55 hours with only 5 at night. You're past the total, but not the night minimum, so you still have 5 hours left, all of them at night.

It works the other way too. With 30 hours logged, 15 of them at night, the night requirement is already met. The 5 extra night hours count toward the total like any other hours, so you have 20 hours left and can drive them at any time.

On rounding: each input goes to the nearest minute, so type 12.5 for 12 hours 30 minutes or 0.25 for 15 minutes. Results show hours and minutes, never decimal hours. Percentages round down, so 49.9 of 50 hours shows 99% while 6 minutes are still left. Weeks to finish round up to the next full week.

Supervised driving hours in six states

These are the six state presets in the calculator. Each figure comes from the state's own licensing-agency page, and the Notes column has the fine print.

Oregon asks for 100 hours of supervised driving, or 50 if you've passed an approved driver ed course, with no night minimum. For a state like that, pick Custom and enter 0 for night hours. Two states set no minimum at all: the IIHS graduated licensing table lists one for every state plus DC except Arkansas and Mississippi.

Requirements vary and change. Check your state's licensing agency before you plan. Our guide to how long it takes to log 50 supervised driving hours has a 12-state table with permit holding periods, plus the pacing math.

When your state lists day hours separately

Nevada and Ohio both count night hours inside the total, but they also print a separate day figure. Nevada's DMV page says "You must complete at least 50 hours of supervised driving, including 10 hours at night," then shows "40 Hours Day Time / 10 Hours Night Time." The log in Ohio's BMV 5791 says "Minimum of 50 hours of required supervised driving. 40 hours of day time driving and 10 hours of night time."

Neither says extra night hours are refused. Read strictly, though, a 40-hour day line only fills with day driving. So when you've logged more night hours than your state requires, the calculator adds a note with the stricter figure: the required day hours minus the day hours you've logged.

Take 50 hours required with 10 at night, and 30 logged with 15 at night. The main result is 20 hours left, to drive at any time. The note says that if extra night hours don't fill the day line, you'd have 25 hours of day driving left: 40 required, minus the 15 you drove by day.

That's why the note says extra night hours "may not" count as day hours. It shows even when you've met the total, because that's when a Nevada or Ohio learner is most likely to stop logging. Check the wording on your own state's form.

Keep a log you can copy onto your state's form

A calculator tells you where you stand, but many states want their own signed form or log. Nevada accepts only the RoadReady app or its DLD-130 form, and Ohio's BMV 5791 affidavit, which must be notarized, has its own log section. That form is the official record. Our driving log template vs app guide covers what six states accept.

Road44 is the running log we built for that, so your totals are current after every drive:

• Choose Hours as your goal, then set an all-time target and a night-hours sub-goal. Both are free, and the home screen shows your progress toward each.
• Live drives get a day or night flag from the start time, based on sunrise and sunset. State definitions differ (Ohio's night starts half an hour after sunset), so check dusk drives and flip the day/night switch on the entry form when needed.
• The supervisor field records who rode along, and past names come up as suggestions.
• The logbook exports free as Text, CSV, PDF or PNG, with no watermark, so you have a record to copy onto your state's form.

Road44 is a personal record, not an official or certified logbook, and it doesn't replace your state's form. Drives stay on your phone, with no account. If several supervisors log on different phones, our roundup of driving hours tracker apps compares apps that use accounts and support several drivers. In Ohio, RoadReady Ohio is the only app the state's form names; see Road44 vs RoadReady Ohio.
