During a collision investigation, which evidence is considered most reliable?

Traffic camera footage is considered the most reliable evidence during a collision investigation because it provides an unbiased, objective recording of the event as it occurred in real time. This type of evidence captures the circumstances of the collision without the influence of personal interpretation or memory distortion that may affect witness statements. The footage can also include important details such as the speed of vehicles, traffic signals, and the behavior of all parties involved, which can be critical in reconstructing the incident accurately.

In contrast, while witness statements can offer valuable insights, they are often subjective and can vary significantly based on the individual's perspective and recollection. Vehicle damage can provide important clues about the nature of the collision, but it may not capture the full context of what happened. Skid marks are helpful for understanding vehicle dynamics but are less definitive compared to the clear, visual evidence provided by traffic camera footage.
