How are advanced driving privileges indicated on an Airport ID Badge?

Advanced driving privileges on an Airport ID Badge are indicated by a red stripe. This visual cue serves as a clear and distinct marker for airport personnel and security to identify individuals who have received specialized training or certification necessary for operating vehicles in restricted areas of the airport. Such identification is crucial for maintaining safety and security within airport operations, particularly in high-traffic zones where only authorized personnel are allowed to drive. Consequently, the use of a red stripe provides an immediate and recognizable means of denoting these privileges.
