Purpose

To provide a standardized method for internal auditors to review driver logbooks and ELD data for accuracy, completeness, and regulatory compliance. Timely detection of HOS violations reduces crash risk, avoids enforcement penalties, and supports a culture of safety. This procedure also creates an auditable record of the audit itself for use during carrier safety rating assessments.

Scope

This SOP applies to all commercial vehicle drivers operating under the authority of a Canadian carrier subject to CMVTA, and to any cross-border operations subject to FMCSA Part 395. It covers both paper logbook and ELD record audits for single-day and multi-day trips. The procedure is intended for use by safety departments, fleet managers, and third-party auditors. It does not cover accident reconstruction or cargo securement verification.

Safety Precautions

LOTOLockout/Tagout electronic logging device (ELD) during removal? No – do not tamper with ELD hardware during audit. Only software/cloud data is reviewed.
PPENo special PPE required for desktop audit. If reviewing physical logbooks in vehicle cab, use gloves and ensure vehicle is parked with engine off, wheels chocked.
DATAProtect confidentiality of personal driver information. Store audit reports in a locked or encrypted repository.

Procedure: Step-by-Step

1 Gather all driver logbooks and ELD records for the audit period (typically the last 7 or 14 days). Verify that each driver has submitted their daily logs and that the ELD data has been properly uploaded and signed off. Print or export the logs to a consistent format for review.

2 Cross-check each log against the dispatch and route plan. Use the dispatch schedule to confirm that the driver’s on-duty, driving, off-duty, and sleeper berth periods match the planned timeline. Flag any discrepancies of more than 15 minutes. Note: unassigned driving events (ELD) must be investigated.

3 Verify that driving time does not exceed regulatory limits: 13 hours (Canada) or 11 hours (US) of driving per day. Confirm cycle limits: 70 hours (Canada/7-day cycle) or 60 hours (US/7-day cycle for passenger). Use a cumulative calculation spreadsheet if data is not aggregated by the ELD system.

4 Inspect each log for completeness: ensure every duty status change is recorded, the carrier name, unit number, trailer number, and shipping document numbers are present. For paper logs, check that grid entries are legible and that the driver’s signature and hours totals are entered. Reject any log with missing fields.

5 Identify any HOS violations or near-violations (e.g., driving over 11 hours, on-duty over 14 hours, insufficient off-duty / 30‑minute break before driving). For each violation, document the driver name, date, nature of violation, and root cause. Attach the flagged log entry as evidence. Use a violation tracking sheet.

6 Summarize audit findings in a compliance report. Include total violations, corrective actions taken (retraining, warning letter, or escalation), and a recommendation for follow-up audit frequency. Upload the report and logbook copies to the company’s document management system (SiteQueue “Audit Log” folder recommended).
