How to Correctly Fill Out a Driving Log

The driving log is a critical tool for compliance with hours of service (HOS) regulations and for maintaining accurate records of a driver’s on-duty time, driving time, and rest periods. This guide provides a clear, step-by-step approach to correctly completing a driving log, whether using a paper log or an electronic logging device (ELD). It also highlights common mistakes and best practices to ensure accuracy, legality, and efficiency in daily operations.

Understanding The Purpose And Requirements Of A Driving Log

A driving log records daily driving activity to demonstrate compliance with FMCSA Hours of Service rules. It documents on-duty time, driving time, cycle start dates, rest periods, and duty status changes. For most commercial drivers, the log substantiates weekly duty status reports and supports audits or inspections. In the United States, the transition to ELDs began to standardize records; however, paper logs remain acceptable in limited circumstances with specific exceptions. The key requirement is that entries must reflect an accurate timeline, with no gaps or unsubstantiated periods.

Key Fields And Data To Capture

A typical driving log (paper or electronic) includes several essential fields. When filling out a log, ensure each entry clearly reflects the following:

• Date and driver identification—the calendar date and the driver’s name or identifier.
• Log time period—start and end times for each duty status period, recorded in local time.
• Duty status—Off Duty, Sleeper Berth, Driving, or On Duty Not Driving. For ELDs, these statuses auto-log, but drivers must verify accuracy.
• Vehicle and carrier information—vehicle number, trailer number (if applicable), and motor carrier details.
• Total driving time—sum of driving periods within the log period (usually per 24 hours).
• Rest and break periods—documented rest times to demonstrate compliance with minimum rest requirements.
• Notes or remarks—optional fields to explain unusual activities, delays, or corrections.

For accuracy, entries should be precise to the minute when possible, and any changes to duty status must be recorded with the corresponding timestamp.

Steps To Fill Out A Paper Driving Log

Follow these steps to complete a paper log accurately. These steps help prevent common mistakes and ensure compliance with HOS rules.

1. Record the date and the driver’s identification at the top of the log sheet.
2. Fill in the initial duty status as Off Duty unless the driver starts in Sleeper Berth or Driving, depending on the situation.
3. Log each shift or duty period by noting the start time, end time, and the corresponding duty status.
4. Calculate and enter the total driving time for the 24-hour period, ensuring it aligns with HOS limits.
5. Document any periods of rest and ensure rest times meet the required duration for the applicable cycle.
6. Mark any corrections with a clear notation, date, and initials to preserve the integrity of the log.
7. Review the log for gaps or ambiguities; fill any missing times to maintain a continuous record.
8. Sign and date the log once all fields are complete and accurate.

Steps To Use An Electronic Logging Device (ELD)

ELDs automatically record driving activity based on engine data and synchronizes with the driver’s status inputs. Accurate use requires verification and timely corrections when necessary.

• Ensure the ELD is properly connected to the vehicle and linked to the correct driver profile and carrier information.
• Verify that duty status transitions (Off Duty, Sleeper Berth, Driving, On Duty Not Driving) are correctly captured in real time.
• Review the daily and weekly logs for accuracy; correct any misclassifications or missing data using the approved methods.
• Export and retain logs for the required retention period, typically six months in digital format, with backup copies.

Common Mistakes And How To Avoid Them

Awareness of typical errors helps prevent penalties and audits. Common issues include:

• Gaps in time—Always ensure there are no unlogged periods. If a gap occurs, backfill with the correct status and timestamp.
• Incorrect duty status—Double-check transitions between On Duty, Driving, and Sleeper Berth to reflect actual activity.
• Incorrect total driving time—Regularly recalculate daily driving time to ensure it complies with hours limits.
• Unclear remarks—Use clear notes to explain delays, weather, or equipment issues; avoid vague entries.
• Missing supporting details—Maintain carrier and vehicle identifiers to facilitate audits.

Best Practices For Accurate Record-Keeping

Adopting disciplined habits improves accuracy and compliance. Key practices include:

• Daily review—Check logs at the end of each shift to catch errors early.
• Standard operating procedures—Implement a consistent process for logging and approving entries across the fleet.
• Regular audits—Periodically review logs for compliance with FMCSA rules and internal policies.
• Backups—For ELDs, ensure secure backups of all data; for paper logs, maintain organized archives.
• Training—Provide ongoing training on HOS rules and correct logging techniques for new drivers and staff.

Compliance And Legal Considerations

Adherence to Hours of Service regulations is essential to avoid penalties, which may include fines or out-of-service orders. Key regulatory points include:

• Drivers must not drive beyond the daily and weekly driving limits and must take mandatory rest breaks where required.
• ELD mandates require accurate, tamper-evident electronic records of duty status and driving time.
• Paper logs are permissible only in limited scenarios, such as ELD malfunction or specific exemptions, and must be kept with integrity.
• Records must be retained for the required period, typically six months for logs, with availability for inspection upon request by authorities.

Tips For Quick, Accurate Entry On Busy Days

Busy schedules can complicate logging. These tips help maintain accuracy without slowing operations:

• Use standardized abbreviations and times to reduce mistakes and speed up entry.
• Leverage ELD features such as auto-fill and status alerts, while validating accuracy before finalizing.
• Conduct a quick end-of-day reconciliation to ensure the log matches actual routes, stops, and rest periods.
• Keep a small, portable reference sheet with common duty-status transitions for quick confirmation.

Comparing Paper Logs And Electronic Logs

Understanding the differences helps fleets choose the right approach and prepare for audits. The table below highlights key distinctions:

Final Checks Before Submission

Before submitting or presenting logs for audit, drivers and supervisors should perform a final verification:

• Confirm that each log period has a clearly defined status and timestamps.
• Verify total driving time aligns with the 11-hour daily limit and Driver’s Hour of Service cycle rules.
• Ensure rest periods meet the required duration and are properly logged.
• Check for any missing or inconsistent entries and correct promptly with proper notations.
• Retain copies of the logs in the required format and location for the mandated retention period.
