How many vehicles are permitted to pass through a roll gate simultaneously?

Only one vehicle is permitted to pass through a roll gate at the same time to ensure safety and maintain control over vehicle movement in secure areas. This restriction helps prevent congestion and minimizes the risk of accidents that could occur if multiple vehicles attempted to use the gate simultaneously. Hence, the regulation is essential for managing access to restricted zones, particularly within airport operations where safety protocols are paramount. The presence of only one vehicle at a time allows for proper monitoring and ensures that all security measures are adhered to effectively.
