Question: if your plows already carry cameras, can the footage help you spot edge damage mid-storm? Short answer: it can show the effects of a damaged edge, but it cannot measure wear. Treat video as a prompt to inspect, not as an inspection.
What footage can reasonably show
| Visible on video | Possible meaning | Action |
|---|---|---|
| A narrow strip of snow or slush left behind | A segment worn lower, missing or lifted by a shoe problem | Stop and look at the edge at the next safe place |
| A sudden change in sound or sparks, if audio or night footage shows it | Contact with a raised cover or a loose part | Inspect the edge and mounting after the pass |
| A hard impact moment with an object | Possible bent edge or loosened bolts | Use the impact triage list, then log the time |
| Repeated streaks at the same location | A fixed feature on the route, not a worn edge | Report the location to the route supervisor |
What it cannot show
A camera shows the surface, not the edge height.
- Remaining edge height. Cameras do not look at the cutting edge from a measuring position.
- Whether carbide inserts are intact or whether bolts are tight.
- Wear shape. Photographs taken at the shop are the right tool.
The records side
Clear Roads’ synthesis 23-S1, completed in August 2024, collects policies and practices on how agencies manage the retention and dissemination of video and images from truck-mounted cameras, considering personal privacy and legal issues. If you plan to use footage for equipment records, check your agency’s retention and access policy first, and decide who may view clips of drivers.
Why not rely on video alone
A worn edge often leaves no visible mark on the road until it is very worn, and the camera angle usually shows the lane ahead and not the blade. That is why a short physical check at the shift change remains the reliable method, and why video is best used to decide when to stop and look.
A workable routine
The routine is a trigger, not a continuous watch.
- Pick a trigger: a streak report, an impact, or a driver call.
- Save the clip with truck number, time and location.
- Inspect the edge and note height and damage on the same record.
- Review a sample of clips weekly for patterns, not for blame.
Boundary: I did not find a published study measuring how well cameras detect edge damage. The table above is reasoning about what video can show, not a result from research.
