What is a corroborative sign in tracking?

• A. Something that indicates the exact direction of travel
• B. Something that supports or confirms what you are observing in the track or scene
• C. A sign created by weather
• D. A sign that is always more reliable than conclusive signs

Answer: (B)

In tracking, corroborative signs are pieces of evidence that support what you’re directly observing in the track or scene. They aren’t the actual trace itself, but they help confirm your interpretation by aligning with the main sign. For example, if you’ve found a clear boot print, corroborative signs might be nearby disturbed vegetation, scuffed grass, or soil and debris arrangements that match the direction and pattern of the print. When several corroborative signs line up with the primary track, your confidence about where the subject went and how they moved increases.

Weather-related signs can affect scenes, but they aren’t what we mean by corroborative signs. And corroborative signs aren’t inherently more reliable than the direct, conclusive signs—the actual track or footprint—because the key value of corroboration is to reinforce what you see, not to replace the direct evidence.
