On a vision-obscured road, how far behind should flags (triangles) be placed?

The requirement for flag placement on a vision-obscured road is typically about 10 feet behind the vehicle or hazard. This distance ensures that the flags are visible to approaching traffic from a reasonable distance, allowing drivers ample time to react. The placement of the flags effectively communicates to other road users that there is an obstruction or a situation requiring caution ahead.

Understanding the significance of the spacing is crucial for safety in situations where visibility is limited, as it directly impacts how drivers perceive and respond to potential hazards. Ensuring that the flags are adequately spaced at this distance balances visibility and safety, providing a clear warning to oncoming traffic without being too close to the hazard, which could lead to confusion or accidents.
