When is it permissible to use terminal service roads?

Using terminal service roads is permissible when there is an operational requirement. This means that if there is a specific need for access—such as transporting equipment, passengers, or supplies in relation to airport operations—vehicles are allowed to use these roads. The operational requirement ensures that the access is necessary for safety and efficiency in managing airport activities.

In contrast, unauthorized vehicles are not permitted on terminal service roads, as this could pose a safety risk. The absence of aircraft traffic alone does not justify the use of the roads, as the primary consideration is operational necessity rather than just the current traffic conditions. While maintenance vehicles have designated privileges, the use of these roads is not exclusively reserved for maintenance activities; it can extend to other operational needs too, reinforcing the importance of adhering to authorized use when circumstances demand it.
