Which statement describes an open column convoy formation?

Which statement describes an open column convoy formation?

• A. Vehicle intervals: 25-50 meters; Speed: < 25 mph; Greatest degree of control.
• B. Vehicle intervals: 100 meters +; Speed: > 25 mph; Preferred formation; Used on well marked open roads with good visibility.
• C. No defined structure, variable interval and speed.
• D. Vehicle intervals: 50-75 meters; Speed: 10 mph; Used on rough terrain.

Answer: (B)

Open column is about moving fast with wide spacing on well‑marked, straight roads where visibility is good. The large intervals—often 100 meters or more—give each vehicle ample reaction time and make it easier to react to hazards or to overtake if needed. Speeds are higher, typically over 25 mph, because the road conditions permit it and the spacing reduces the risk of collisions in a moving convoy. This combination—long intervals with higher speed on clear routes—fits the open column use case best. Other descriptions describe tighter spacing or slower speeds suited to rough or uncertain terrain or nonstandard movements, which is why they don’t characterize open column.
