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

Transient Alert "Follow Me" vehicles are specifically designed and sanctioned to operate in the path of taxiing aircraft. These vehicles play a critical role in guiding aircraft from the runway to the taxiway or gate, ensuring that they have a clear path and that safety protocols are followed. The presence of specially trained personnel in these vehicles helps facilitate safe movement around the airfield, as they are equipped with lights, flags, and communicate with air traffic control to coordinate the movement of both aircraft and ground vehicles.

Other types of vehicles, such as ground service vehicles, maintenance vehicles, and emergency response vehicles, have specific operational guidelines that typically refrain from entering active taxi areas unless under directed circumstances. While emergency response vehicles may have more flexibility due to the nature of their duties, they are not routinely allowed to operate in the direct path of taxiing aircraft as a standard practice, as this could pose safety risks.
