What is the purpose of a driver logbook?

A driver logbook serves as a record of a commercial driver’s hours worked, rest periods, and activities throughout the day. Its primary purpose is to ensure compliance with Hours of Service (HOS) regulations, which are designed to prevent driver fatigue and promote road safety.

• Driving hours: Tracks time spent operating a vehicle.

• On-duty (not driving): Captures time spent loading, unloading, or performing other work-related activities.

• Off-duty periods: Includes rest breaks, meal times, and sleeper berth hours.

Accurate logbooks are critical for:

• Safety compliance: Ensuring drivers are well-rested.

• Inspections: Providing proof of HOS compliance during roadside checks.

• Audits: Demonstrating adherence to regulations during carrier audits.

Failure to maintain accurate logbooks can result in fines, out-of-service orders, or legal consequences.
