How should trailers' VINs be affixed if not accessible on the tongue?

The correct approach for affixing a trailer's Vehicle Identification Number (VIN) is to place it on the outside left tongue as close to the front as possible. This location ensures that the VIN is easily visible and accessible for inspection and identification. The tongue of the trailer is a prominent area where law enforcement and inspection personnel typically look for the VIN, making it a logical choice.

Placing the VIN in this location also helps to avoid any potential issues that could arise from placement inside the trailer or in less accessible areas. If the VIN is positioned inside the trailer or under the body, it might not be readily visible or easily traceable during routine checks, which could lead to complications in registration or when needed for identification in various situations. Placing it on the left side of the tongue maintains consistency with regulatory standards and facilitates easier compliance during inspections.
