Which document must be presented during the AVOP application process?

During the AVOP application process, it is necessary to present a valid driver's license. This requirement exists because the AVOP is specifically focused on ensuring that individuals operating vehicles on the airside have the necessary skills and legal authority to do so safely. A valid driver's license demonstrates that the applicant has undergone the appropriate training and examination to operate a vehicle on public roads, which is a fundamental aspect of airside vehicle operation as well.

The other documents listed, while important in different contexts, do not specifically validate one's ability to operate vehicles in the airport environment. A passport primarily serves as a means of identification for international travel, a birth certificate is typically used for establishing identity or age, and a social insurance number is related to employment and taxation. None of these documents provide the direct recognition of driving competency required for airside operations. Thus, a valid driver's license is the correct document to present when applying for the AVOP, as it directly correlates to vehicle operation capability on the airport premises.
