Which practice supports effective passenger screening?

Providing clear instructions and signage is critical for effective passenger screening because it helps establish clear communication between security personnel and travelers. When passengers understand what is expected of them during the screening process—such as how to prepare their belongings, what items are prohibited, and the steps they need to take—they are more likely to comply with security requirements. This clarity not only speeds up the screening process but also enhances overall safety and efficiency in security operations.

Effective instructions and signage can alleviate confusion and reduce stress for passengers, which can lead to a smoother, more organized screening experience. Additionally, well-placed signs can communicate important safety information and direct passengers to the appropriate areas, helping to maintain order and flow within the screening environment.

While asking random security questions might provide some level of engagement, it is not as systematic or effective as having clear instructions and signage. Relying solely on automated systems can lead to gaps in communication and understanding, while avoiding personal interaction can create barriers and uncertainty for passengers, ultimately detracting from the effectiveness of the screening process.
