Speeding violations under §392.2 are among the most-cited roadside inspection findings in the Unsafe Driving BASIC. The CFR section requires CMV drivers to comply with the posted speed limit and any traffic laws of the jurisdiction in which the vehicle is being operated.
Severity weight
Speeding violations are tiered:
- Speeding 1–5 mph over: weight 1
- Speeding 6–10 mph over: weight 4
- Speeding 11–14 mph over: weight 7
- Speeding 15+ mph over: weight 10
- Speeding in a construction zone or work zone: weight 10
The weighted score directly affects your CSA Unsafe Driving BASIC percentile.
How to prevent it
The obvious answer is: don't speed. Beyond that, common contributors:
- ELD pressure. A driver close to running out of duty hours may push the limit. Build dispatch buffers so the route doesn't require speeding.
- Speed limiters. Many fleets set governor-limited top speeds. For a single-truck operation, awareness and habit are the main controls.
- Construction zones. Lower posted limits apply, and the severity weight doubles. Brief drivers explicitly when a route includes a known construction zone.
How Roadworthy HQ helps
Roadworthy HQ logs every roadside inspection result against the driver and vehicle, tracks the corrective action you took (driver coaching, retraining, dispatch review), and surfaces patterns over time. CSA scores are pulled from the FMCSA Safety Measurement System; the corrective action documentation is what an auditor wants to see when an Unsafe Driving spike appears.
