What is allowed to be used if the inspection certificate is placed properly to prevent theft?

The use of a holder to properly place the inspection certificate is important for ensuring that the certificate remains visible and securely attached to the vehicle. A holder designed specifically for inspection certificates protects the document from environmental damage, such as rain or sun exposure, while also making it more difficult for someone to remove or steal it. This adherence to proper display regulations ensures that the vehicle complies with inspection requirements, allowing law enforcement and inspection personnel to easily verify that the vehicle has passed its safety inspection.

Other options like a mobile device might not provide the necessary physical security or visibility required for the certificate. Similarly, while a lock might secure the vehicle or compartment, it doesn't specifically address the need for displaying the certificate itself. A cover could potentially protect the certificate, but without a holder designed for this purpose, it may not secure the certificate in a way that prevents theft or loss. The holder is the most effective option to fulfill the requirements of visibility and security for the inspection certificate.
