What can be a consequence of failing to address obstructions in a crash investigation?

In a crash investigation, failing to address obstructions can lead to inaccurate conclusions about driver behavior. This is critical because obstructions, such as road signs, debris, or other vehicles, can significantly influence how a crash occurs and how drivers react in a given situation. If these factors are not taken into account, investigators may misinterpret the actions of the drivers involved, assume fault incorrectly, or overlook key elements that contributed to the incident.

Accurate assessment of all factors, including obstructions, is essential for understanding the full context of a crash. This understanding helps ensure that the investigation's findings are grounded in reality, which is vital for determining accountability and preventing future incidents. The other options either minimize the importance of addressing obstructions or suggest that they are irrelevant, which is contrary to the comprehensive nature of effective crash investigations.
