Which type of vehicle is allowed to operate in the path of taxiing aircraft?

Follow-me vehicles are specifically designed to guide and direct aircraft on the ground, leading them to and from taxiways and runways. These vehicles operate in the path of taxiing aircraft under controlled circumstances, ensuring safe navigation and minimizing the risk of accidents. Their presence is coordinated with air traffic control or other ground operations, which provides an additional layer of safety during aircraft movements.

While emergency response vehicles and service vehicles do operate on airfields, their movements are usually restricted to specific protocols that do not involve directly guiding or interacting with taxiing aircraft in a manner similar to follow-me vehicles. Private vehicles are typically not permitted to operate on the airfield at all due to safety concerns regarding proximity to active operations.
