What is the two-person method for Stop-Check-Pass?

• A. Inspect second vehicle first; never block lane.
• B. Inspect first vehicle, then second before first leaves; always keep a vehicle blocking lane.
• C. Inspect both vehicles simultaneously without blocking.
• D. Inspect only one vehicle and let it leave before inspecting the second.

Answer: (B)

The two-person Stop-Check-Pass approach relies on coordinated teamwork and strict sequencing to keep the checkpoint under control. One operator handles the inspection of the first vehicle, while the other manages the lane by positioning a vehicle to block flow and prevent other traffic from moving forward into the stop area. The key is to inspect the first vehicle, then bring in the second for inspection, and only after the second is inspected do you allow the first to depart. Maintaining a blocking vehicle in the lane ensures there’s always a physical barrier, so no uninspected vehicle can sneak into or through the checkpoint while inspections are in progress.

This setup minimizes security gaps by guaranteeing both vehicles are checked in a controlled order and by preventing tailgating or circumvention of the process. It’s safer and more orderly than trying to inspect both at once, or letting a vehicle leave before the second is checked, or not using a blocking vehicle to control entry.
