DVIR in trucking refers to a Driver Vehicle Inspection Report (DVIR). A driver’s vehicle inspection report in trucking is a formal record done each day that confirms that the commercial motor vehicle, such as a truck or bus, is safe for operation. A driver completes this daily to let their organization know about any unsafe or missing equipment on their vehicle. Drivers must complete pre-trip and post-trip inspections and report on any mechanical defects. These inspections help improve road safety and are key to ensuring fleet compliance.
