To prepare for a NSC facility audit, carriers need to ensure all the necessary documents and records that the auditor may request are available, such as:

• Authority to operate commercial vehicles, such as licences, permits, registrations, etc.
• Daily commercial trip inspection reports, which include pre-trip and/or post-trip commercial vehicle inspections.
• Maintenance records, such as service schedules, repair invoices, defect reports, etc.
• Driver qualification files, such as driver licences, medical certificates, driver abstracts, training records, etc.
• Hours of service records, such as logbooks, timesheets, supporting documents, etc.
• Accident reports, such as police reports, insurance claims, investigation reports, etc.

Carriers must ensure that vehicles are in good condition and meet the CVSA inspection standards. Carriers may conduct a self-audit or hire a third-party auditor to identify any areas of improvement or non-compliance before the official audit.
