What is the primary purpose of the Blue-Stripe logo on a towing vehicle?

The Blue-Stripe logo on a towing vehicle serves the essential purpose of identifying authorized towing vehicles on airport property. This logo is a clear visual indicator that the vehicle is recognized by airport authorities, ensuring that it meets specific safety and operational standards necessary for functioning within the busy environment of an airport like O’Hare. Having this identification prominently displayed helps in maintaining security and operational efficiency, as it allows airport personnel and other drivers to quickly recognize which vehicles are authorized to perform towing services.

The other options do not reflect the role of the Blue-Stripe logo. Personal use vehicles, fuel types, or maximum speeds are not pertinent to the operational integrity and security measures necessary when maneuvering in an airport's sensitive zones. The focus is on ensuring that only qualified and approved vehicles are utilized, thereby enhancing safety and service reliability at the airport.
