What convoy movement formation can only be used on multilane roads?

The staggered convoy formation is specifically designed for multilane roads, allowing for greater maneuverability and enhanced safety. In a staggered formation, vehicles are positioned in a way that provides increased space between them, reducing the risk of collision and enabling drivers to respond more effectively to sudden changes in traffic conditions. This formation capitalizes on the availability of multiple lanes, allowing vehicles to spread out while maintaining a cohesive structure.

In contrast, other formations such as column and file are more suited for situations where traffic is limited to fewer lanes or when traveling through tighter spaces, as they keep vehicles more closely aligned and can limit maneuverability. The offset formation, while it can also be used in multilane conditions, does not provide the same level of spatial arrangement as the staggered formation, which is why it is less suitable as a specific response in this scenario. Thus, the staggered formation stands out as the optimal choice when navigating multilane roads.
