Frequently Asked Questions (FAQs) for Pre-Trip Single Trailer Inspection (DVIR)
What should I do if I find a problem during the pre-trip trailer inspection?
Any issues discovered during the pre-trip inspection should be documented and reported to the maintenance team immediately. Do not operate the trailer until all necessary repairs are confirmed and the trailer is deemed safe for use.
How often should a single trailer undergo a pre-trip inspection?
A pre-trip inspection should be conducted every time the trailer is about to be used. This ensures that any issues that could have arisen since the last use are identified and addressed promptly.
Which parts of the trailer are most crucial to check during a pre-trip inspection?
While it’s important to check every aspect of the trailer, the braking system, tires, and lights are particularly crucial because they directly affect the safety of the trailer’s operation. Also, ensure the coupling devices are secure to prevent disconnection during transit.
Can the driver perform the pre-trip inspection, or is a mechanic required?
Drivers are typically trained to perform pre-trip inspections as they are straightforward and do not usually require specialized mechanical skills. However, if any complex issues are found, a qualified mechanic should then inspect and repair the trailer.
What documentation should be maintained for pre-trip trailer inspections?
