Non-compliance with HOS regulation, including log books, is described as what?

• A. Hours of service not compliance
• B. HOS violation
• C. Logbook discrepancy
• D. Scheduling violation

Answer: (A)

Non-compliance with HOS rules is about failing to meet the required hours of service, including how logbooks are used to document driving time and rest. The best description is hours of service not compliance because it states the status directly: the driver is not in compliance with the hours-of-service regulations. This label captures the overall failure to meet HOS requirements, not just a single issue like a log entry error or a scheduling mistake. The other terms describe more specific problems—a general HOS violation points to non-compliance but uses a broader label, a logbook discrepancy focuses on an error in records, and a scheduling violation targets planning issues—whereas the phrase in question emphasizes the overarching non-compliance with HOS.
