Open column formation is best described as which of the following?

Open column formation is best described as which of the following?

• A. Vehicle intervals: 25-50 meters; Speed: < 25 mph.
• B. Vehicle intervals: 100 meters +; Speed: > 25 mph; Used on well marked open roads with good visibility.
• C. No defined structure, variable interval and speed.
• D. Vehicle intervals: 50-75 meters; Speed: 15 mph.

Answer: (B)

Open column is a convoy setup designed for high-speed movement on open routes with good visibility, where you can maintain a relatively large gap between vehicles. The idea is to give drivers ample stopping and maneuvering space, because speeds are higher and hazards can require quick responses. Using 100 meters or more between vehicles lets you safely react to sudden events, reduces the risk of chain-reaction collisions, and allows easier passage around obstacles without forcing others into tight, risky spacing. This setup works best on well-marked open roads where visibility is clear, so drivers can see ahead far enough to maintain the longer following distances and stay in their lane confidently. The other descriptions imply tighter spacing or slower speeds, or conditions that aren’t conducive to maintaining a safe, orderly open-column flow, which is why they don’t describe open column as accurately.
