Section 392.16 requires the driver of a CMV equipped with a seat belt assembly to use that assembly while the vehicle is in motion. The violation is driver-assigned and one of the most-cited under the Unsafe Driving BASIC.
Why this matters
Beyond the safety reasons, seat belt violations:
- Show up in your CSA Unsafe Driving percentile at severity weight 7 (out of 10).
- Are one of the items roadside inspectors check on every Level III walk-around inspection.
- Often correlate with a deeper culture issue — fleets with frequent §392.16 violations frequently have other Unsafe Driving findings.
How to prevent it
- Coach drivers explicitly: every time the truck is moving, the belt is on.
- For solo owner-operators: build the muscle memory. Belt before the parking brake comes off.
- Document your safety policy and supervisor follow-up. After an audit, the auditor wants to see the corrective action — not just the violation.
How Roadworthy HQ helps
Roadworthy HQ logs every roadside inspection finding and links it to the driver record. Repeated patterns appear in the dashboard — so by the time an auditor pulls your CSA scores, you have the corrective action documentation in hand.
