Which requirement must be met for drivers to avoid violating hours of service limits?

To comply with hours of service requirements, drivers must accurately record their driving hours to ensure they do not exceed the regulated limits. Keeping a log in a format that is accessible for inspection is crucial for transparency and regulatory compliance. Recording hours in duplicate allows for verification and helps maintain accurate records, which can be inspected by law enforcement or regulatory agencies. This redundancy ensures that even if one log is lost or damaged, there is still a reliable record available for review.

Other options do not adequately meet compliance requirements. A single-entry system may lead to errors or inaccuracies, while only reporting hours weekly might not capture daily driving data necessary for compliance with limits. Exclusively using electronic logbooks could be beneficial, but it does not inherently satisfy the requirement of ensuring logs are ready for inspection unless they are also clear and accurate.
