Hours of Service Violations: Common Mistakes and How to Avoid Them

Hours-of-service problems are among the most cited violations at roadside and in audits. Most are avoidable once drivers understand the core limits.

The core limits (property-carrying drivers)

• 11-hour driving limit after 10 consecutive hours off duty
• 14-hour window — you cannot drive beyond the 14th hour after coming on duty, even with breaks
• 30-minute break required after 8 cumulative hours of driving
• 60/70-hour limit over 7/8 consecutive days
• 34-hour restart — optional way to reset the weekly clock

The violations auditors see most

Form-and-manner errors

Logs missing required fields, unassigned driving time, or edits without annotation. ELDs reduce these but do not eliminate them.

Missing supporting documents

Fuel receipts, bills of lading, and dispatch records are used to verify logs. Gaps make logs look falsified even when they are not.

14-hour window violations

Drivers often watch the 11-hour driving clock but forget the 14-hour window keeps running through breaks and loading time.

Personal conveyance misuse

Logging driving as personal conveyance to extend a day is a red flag. Use it only as intended.
