Start with a list of all drivers who perform cross-border road haulage. For each person record nationality, residence status, employment or provision arrangement and intended assignment. This shows for whom an Article 5 driver attestation may be relevant.
Then review the document chain: application, issued attestation, serial number, validity period, original in the vehicle and certified copy at the business. One filing exercise is not enough if the legal or factual conditions of the driver assignment change.
An inspection response should address the particular person and the particular assignment. The attestation is evidence for that driver. It does not replace the general review of the Community licence or the other records required for road haulage.
