A photo of tire marks is critical evidence because tire marks are vulnerable.

• A. True
• B. False
• C. Not sure
• D. Depends

Answer: (A)

Tire marks are a fragile form of trace evidence that can disappear or change quickly if the scene is disturbed, exposed to weather, or cleaned. A photograph preserves their exact appearance at the moment of the incident, capturing size, shape, tread pattern, depth cues, and the direction of travel. This provides a lasting, court-admissible record that analysts can analyze later and compare to suspect tires. To maximize usefulness, photos should include a scale and show the surrounding context so measurements and relationships can be assessed. They should be taken before any sweeping or moving of vehicles, and from multiple angles with good lighting to reveal details that might not be visible from one view. Because of their vulnerability, a photo is indeed a critical piece of evidence for tire marks.
