The log graph looks intimidating until you know the four lines and the totals. Once you do, you can spot a problem on your own day in about ten seconds.
Every ELD log is built from four statuses, drawn as four rows on the graph:
| Status | Means |
|---|---|
| Off Duty | Not working — your time is your own |
| Sleeper Berth | Resting in the bunk (see split sleeper) |
| Driving | Vehicle in motion — counts toward your 11 |
| On-Duty (Not Driving) | Working but parked: fueling, inspection, loading |
The horizontal axis runs midnight to midnight. Each status is a row; the log draws a vertical line every time you switch. The length of each horizontal segment is how long you spent in that status, and the totals on the right must add up to 24 hours. If they don't, something's missing.
Above the grid is the header — carrier name, truck and trailer numbers, DOT number, and start odometer. Below it, remarks record location changes and annotations. Blank header fields are one of the most common form-and-manner violations, so they matter even when your hours are perfect.
TruckSpot shows your day as a clean graph with running 11/14/70 totals, flags gaps, and lets you transfer the log to an inspector in one tap. Spot the missing location or the stray on-duty segment yourself — before it becomes a citation.
