Commercial Driver Hours Of Service HOS Internal Audit Checklist
This internal audit checklist verifies driver compliance with federal and provincial Hours of Service (HOS) regulations under DOT, NSC, and CVOR standards. It covers daily log accuracy, off-duty periods, cycle limits, and supporting document retention — designed for fleet safety auditors, dispatchers, and compliance officers.
This internal HOS audit checklist provides a structured method for fleet compliance personnel to verify that each driver's logbook — paper or electronic — complies with the daily and cumulative limits defined by the National Safety Code (NSC Standard 9), US DOT Part 395, and CVOR requirements. The audit covers elapsed driving time, mandatory off-duty windows, cycle reset compliance, and the completeness of supporting documents (fuel receipts, toll records, BOLs). Regular use of this checklist reduces roadside out-of-service rates and strengthens due diligence during carrier safety fitness reviews.
- Valid driver license class appropriate for the vehicle (Class 1/3/5) and current medical card on file.
- Driver's daily HOS log (paper grid, EOBR printout, or ELD data export) for the current cycle and prior 14 days.
- Supporting documents: fuel receipts, toll transaction logs, BOLs, and any inspection/scale tickets for the audit window.
- Fleet operating jurisdiction — confirm whether Canada HOS (NSC 9) or US HOS (Part 395) limits apply. Cycle types: South/North for Canada; 60/70-hour for US.
- This audit is a sample and does not replace a formal DOT/NSC compliance review. Adapt thresholds based on your carrier profile and local enforcement zone.
