Space Driving Breaks Before the Stretch Gets Long — Free
Equal spacing matters more than total break time. Work out the longest continuous stretch each day’s break plan actually produces, and see the day where it passes your own comfort limit.
The proof surface
Stop plans schedule where you sleep and pause. This models within-day spacing: how scheduled breaks cut one day’s driving into continuous stretches, using your own limit rather than a legal one.
Why the flat version breaks
Counting total break minutes
Five short breaks bunched together still leave one long stretch.
Assuming equal splits happen naturally
Plan the stop points, or the stretch grows where you skip.
Treating the limit as legal advice
Professional driving-hour rules are separate and stricter.
How to work the rest interval strip
Enter the minutes you expect to drive that day, after overnights. The model assumes breaks split driving into equal stretches, which is the best case for a given number of stops.
Only count scheduled stops you intend to make for rest, not fuel stops you might skip. Two breaks split 300 minutes into three stretches of one hundred minutes each.
The summary reports the worst stretch across days. In the alternate sample a 500-minute day with three breaks still leaves 125 continuous minutes, five over the 120-minute comfort setting.
An extra scheduled break shortens every stretch on that day. If a flagged day cannot take another stop, cut the day’s driving distance instead; the limit you enter is a planning boundary, not an excuse to drive on tired.
What the rest interval strip replaces
| Question | Before | Visible working |
|---|---|---|
| Counting total break minutes | Five short breaks bunched together still leave one long stretch. | Count the breaks you will really take |
| Assuming equal splits happen naturally | Plan the stop points, or the stretch grows where you skip. | Compare the longest stretch with your limit |
| Treating the limit as legal advice | Professional driving-hour rules are separate and stricter. | Add a break, don’t just slow down |

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Fatigue planning arithmetic with a limit you choose. Not legal compliance for professional driving hours and not a substitute for stopping when tired.
Data note: Everything runs in this browser tab on the rest interval strip: your driving day | planned driving minutes | scheduled breaks stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a paper ticker strip
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the rest interval strip reading, and holds your drafts on this device — one free run, then $ 4 one-time for the layer that keeps filing.
The rest interval strip reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: The summary reports the worst stretch across days. In the alternate sample a 500-minute day with three breaks still leaves 125 continuous minutes, five over the 120-minute comfort setting.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-28, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: Five short breaks bunched together still leave one long stretch. After: the rest interval strip shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this rest interval strip, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a rest interval strip. Return plain rows only: driving day | planned driving minutes | scheduled breaks. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: driving day | planned driving minutes | scheduled breaks. No AI response is executed as code.
