What must occur before a vehicle can be placed back into service after being marked Out-of-Service?

Before a vehicle that has been marked Out-of-Service can be placed back into service, it is essential that the next driver verifies that all identified defects have been remedied and that the Driver Vehicle Inspection Report (DVIR) is updated accordingly. This process ensures that any safety-related issues have been addressed, thereby maintaining compliance with safety regulations. It is critical for road safety that a driver confirms that the vehicle meets all operational standards and has been inspected to be safe for use before taking it back into service.

Updating the DVIR is a crucial part of this procedure, as it documents the condition of the vehicle and the repairs completed, providing accountability and ensuring that all relevant parties are aware of the vehicle's status.

The other options might involve important aspects of vehicle maintenance and compliance but do not specifically address the requirement that the driver must verify the repairs and update the DVIR following the defects. This makes it clear that for a vehicle to safely return to operational status, verification of repairs and documentation is fundamentally required.
