LoadMaster - field results
Every run captured from the live pipeline during development, unedited: SAM 3.1 finds the trailer and the load, calibrated measurements turn pixels into inches, the deterministic 49 CFR 393 rules engine decides, and Muse Spark reads each photo independently as a second opinion.

60COULD NOT TELL
That spread is the point. Where a photo cannot prove a check (strap tension, tie-down ratings, load weight), the app says COULD NOT TELL instead of guessing. A scored set of staged loads with known ground truth is in preparation; until it is published, read these as unedited pipeline output, not accuracy measurements.
Firewood on a utility trailer (side view)
A working load of split firewood. Watch the forward-blocking and weight-placement checks: the rules engine flags what the geometry shows and refuses the rest.

Second opinion (Muse Spark, independent read): Load looks rear-heavy: No · Front of the load is blocked: Yes
Firewood load needs blocking forward and better balance
The front edge is 8.6 in behind the front of the bed with nothing shown blocking it. Shift it forward against the headboard or bulkhead, or add secured blocking for gap under 6 in. Photo estimate puts the bulk 22.7 in behind the axle, more than the +/-19.7 in uncertainty, so it reads rear-heavy. That unloads the tongue and can cause sway. Shift the load forward so bulk sits over or ahead of the axle, then recheck with a new photo. This is a visual estimate only. Tie-down count could not be told. This 8 ft load needs 2 tie-downs. Supply anchor close-ups or tap tie-downs on the photo. Overhang is 0 in with the load at or inside the rear of the bed. Lights and plate need the rear photo cross-check. Edge protection needs a close-up of each strap at each edge. Strength needs ratings and load weight. A photo cannot verify strap tension, tie-down ratings, or load weight.
| Check | Verdict | Finding | Minimum fix |
|---|---|---|---|
| Forward blocking | CHECK THIS | The load can slide forward: its front edge is 8.6 in behind the front of the bed with nothing shown blocking it. Under hard braking that gap is how far the load can surge. | Block the front of the load: shift it forward against the headboard or bulkhead, or place secured blocking so the open gap is under 6 in. |
| Tie-down count | COULD NOT TELL | This load needs 2 tie-down(s) for its length (8 ft), but no tie-downs could be counted: tie-downs are counted from anchor close-up photos plus any you mark by tapping them on the photo, and neither was supplied. Full-frame photos cannot count straps reliably (they are too thin to read at that distance). | |
| Overhang, lights and plate | COULD NOT TELL | Overhang: the load ends at or inside the rear of the bed (0 in overhang). Lights and plate: not checked (needs the rear photo read by the cross-check; segmentation cannot judge whether lights or the plate are obscured). | |
| Weight placement | CHECK THIS | Photo estimate puts the load's bulk 22.7 in behind the axle, more than the +/-19.7 in uncertainty of the estimate: the load reads rear-heavy, which unloads the tongue and can make the trailer sway. This is a visual estimate of where the bulk sits, not a weight measurement. | Shift the load forward so its bulk sits over or ahead of the axle, then recheck with a new photo. |
| Edge protection | COULD NOT TELL | Edge protection cannot be judged from the evidence supplied: it needs a close-up of each strap where it crosses an edge, read for protectors. Take an anchor close-up per tie-down and run the cross-check. | |
| Tie-down strength (aggregate working load limit) | COULD NOT TELL | Tie-down strength cannot be checked from the photo: a photo cannot verify working load limit ratings or load weight, and this check needs both numbers. Missing: no tie-down working load limit ratings were supplied; no load weight was supplied. Supply the load weight and each tie-down's rating and this check runs on those numbers. |

Second opinion (Muse Spark, independent read): Tail lights visible: No · License plate visible: No · Tarp covering the load: No
Excavator overhang blocks lights needs immediate fix
Fix the overhang. The load sticks out 48.5 inches past the rear. The tail lights and license plate are obscured. Shorten or reposition to remove it. If still over 4 feet, add a red flag by day and lights at night on the end.
Forward blocking passes. The front sits 0.0 inches from the front, inside the 6 inch limit.
Tie-down count could not be told. This 25 foot load needs 4 tie-downs. Add anchor close-up photos or tap tie-downs on the photo. Heavy equipment securement could not be told. Supply machine weight, since at or above 10,000 pounds needs 4 tie-downs. Weight placement could not be told from this photo. Supply weight details, since a photo only shows bulk position. Edge protection could not be told. Supply a close-up of each strap at each edge. Tie-down strength could not be told. Supply tie-down ratings and load weight. A photo cannot verify strap tension, tie-down ratings, or load weight.
| Check | Verdict | Finding | Minimum fix |
|---|---|---|---|
| Forward blocking | PASS | The load's front edge sits 0.0 in from the front of the bed, inside the 6 in blocking threshold: it has no real room to slide forward under braking. | |
| Tie-down count | COULD NOT TELL | This load needs 4 tie-down(s) for its length (25 ft), but no tie-downs could be counted: tie-downs are counted from anchor close-up photos plus any you mark by tapping them on the photo, and neither was supplied. Full-frame photos cannot count straps reliably (they are too thin to read at that distance). | |
| Heavy equipment securement | COULD NOT TELL | This is a heavy wheeled/tracked load, but its weight was not supplied, and 393.130's requirements trigger at 10,000 lb: at or above that weight the machine needs at least 4 tie-downs. Supply the machine's weight to decide this check. Whether buckets, booms and other accessories are lowered and secured separately cannot be verified from a photo. | |
| Overhang, lights and plate | CHECK THIS | Overhang: the load extends 48.5 in past the rear of the bed. Lights and plate: the rear photo read reports the tail lights and license plate obscured by the load. | Shorten or reposition the load to remove the overhang; any load still extending well past the rear (over 4 ft) needs a red flag by day and lights at night at its extreme end, and the load itself still has to be fully secured; Reposition the load (or fit auxiliary lights / relocate the plate) so the tail lights and license plate are fully visible from behind |
| Weight placement | COULD NOT TELL | Weight placement cannot be called from this photo: the photo estimate puts the bulk at 41% of the bed length and the bulk sits 189.4 in ahead of the axle (+/-168.3 in), the direction you want, so placement cannot be decided from this photo. A photo shows where the bulk sits, not how heavy it is. | |
| Edge protection | COULD NOT TELL | Edge protection cannot be judged from the evidence supplied: it needs a close-up of each strap where it crosses an edge, read for protectors. Take an anchor close-up per tie-down and run the cross-check. | |
| Tie-down strength (aggregate working load limit) | COULD NOT TELL | Tie-down strength cannot be checked from the photo: a photo cannot verify working load limit ratings or load weight, and this check needs both numbers. Missing: no tie-down working load limit ratings were supplied; no load weight was supplied. Supply the load weight and each tie-down's rating and this check runs on those numbers. |

Forward blocking could not be told. To judge it run the measurement stage with the trailer bed length because there was no trailer bed detection to scale from. This 16 ft load needs 3 tie-downs but none could be counted. To judge the count supply anchor close-up photos or tap tie-downs on the photo. Overhang could not be measured for the same lack of calibration. To judge lights and plate supply the rear photo for the cross-check. Weight placement could not be called for lack of calibration. To help judge it supply trailer bed detection, remembering a photo only shows where bulk sits never how heavy it is. Edge protection could not be told. To judge it take an anchor close-up per tie-down and run the cross-check. Tie-down strength could not be told. To judge it supply tie-down working load limit ratings and load weight. A photo cannot verify strap tension, tie-down ratings, or load weight.
| Check | Verdict | Finding | Minimum fix |
|---|---|---|---|
| Forward blocking | COULD NOT TELL | Forward blocking cannot be judged: there is no calibrated measurement of the load against the bed (no trailer_bed detection in this photo, so there is no bed extent to scale from). Run the measurement stage with the trailer bed length to enable this check. | |
| Tie-down count | COULD NOT TELL | This load needs 3 tie-down(s) for its length (16 ft), but no tie-downs could be counted: tie-downs are counted from anchor close-up photos plus any you mark by tapping them on the photo, and neither was supplied. Full-frame photos cannot count straps reliably (they are too thin to read at that distance). | |
| Overhang, lights and plate | COULD NOT TELL | Overhang: could not be measured (no calibration: no trailer_bed detection in this photo, so there is no bed extent to scale from). Lights and plate: not checked (needs the rear photo read by the cross-check; segmentation cannot judge whether lights or the plate are obscured). | |
| Weight placement | COULD NOT TELL | Weight placement cannot be called: no calibration: no trailer_bed detection in this photo, so there is no bed extent to scale from. Placement is a visual estimate only in any case - a photo shows where the bulk sits, never how heavy it is. | |
| Edge protection | COULD NOT TELL | Edge protection cannot be judged from the evidence supplied: it needs a close-up of each strap where it crosses an edge, read for protectors. Take an anchor close-up per tie-down and run the cross-check. | |
| Tie-down strength (aggregate working load limit) | COULD NOT TELL | Tie-down strength cannot be checked from the photo: a photo cannot verify working load limit ratings or load weight, and this check needs both numbers. Missing: no tie-down working load limit ratings were supplied; no load weight was supplied. Supply the load weight and each tie-down's rating and this check runs on those numbers. |

Ratchet strap anchor (close-up)
One anchor, filling the frame. This is the photo shape tie-down counting is built on: SAM reads a strap at 0.79+ confidence here, versus invisible at full-frame distance.
tiedown closeup 80%
Second opinion (Muse Spark, independent read): Tie-downs it counted: 2 · Strap over a sharp edge with no protection: No
Add one more tie-down before rolling 8 ft steel load
Your 8 ft steel load has 1 tie-down but needs 2. You are short by 1. Add at least 1 more tie-down spaced along the load before rolling. Edge protection passed with no strap or chain crossing a sharp edge without a protector. Forward blocking could not be told. It needs a calibrated measurement of the load against the bed from the measurement stage with the trailer bed length. Overhang could not be told. It needs a measurement run. Lights and plate could not be told. They need the rear photo read by the cross-check. Weight placement could not be told. It needs a centroid measurement and is a visual estimate only. Tie-down strength could not be told. It needs the tie-down ratings and the load weight. A photo cannot verify strap tension, tie-down ratings, or load weight.

|---|---|---|---|
| Forward blocking | COULD NOT TELL | Forward blocking cannot be judged: there is no calibrated measurement of the load against the bed (no measurement run was supplied). Run the measurement stage with the trailer bed length to enable this check. | |
| Tie-down count | CHECK THIS | Only 1 tie-down(s) counted; 393.110 requires 2 for a 8 ft load. Short by 1. | Add at least 1 more tie-down(s), spaced along the load, before rolling. |
| Overhang, lights and plate | COULD NOT TELL | Overhang: not measured (no measurement run supplied). Lights and plate: not checked (needs the rear photo read by the cross-check; segmentation cannot judge whether lights or the plate are obscured). | |
| Weight placement | COULD NOT TELL | Weight placement cannot be called: no centroid measurement was supplied. Placement is a visual estimate only in any case - a photo shows where the bulk sits, never how heavy it is. | |
| Edge protection | PASS | The independent photo read of the anchor close-up reports no strap or chain crossing a sharp edge without a protector. | |
| Tie-down strength (aggregate working load limit) | COULD NOT TELL | Tie-down strength cannot be checked from the photo: a photo cannot verify working load limit ratings or load weight, and this check needs both numbers. Missing: no tie-down working load limit ratings were supplied; no load weight was supplied. Supply the load weight and each tie-down's rating and this check runs on those numbers. |
