Where is it not permitted to place a certificate of inspection on a trailer?

The placement of a certificate of inspection on a trailer is crucial for visibility and compliance with regulations. It is not permitted to place the certificate on the nose or front side of the trailer because this location can interfere with the aerodynamic design and structural integrity of the trailer, and it may also affect visibility for drivers and other road users. Certificates need to be positioned where they are easily visible to law enforcement and inspection personnel, which is more easily achieved on the sides or rear of the trailer, rather than on the front where they can be obscured or damaged. This ensures that the certificate is not only compliant with safety regulations but also effective in communicating that the vehicle has passed inspection.
