What is the first step crash investigators should take upon arriving at a crash scene?

Upon arriving at a crash scene, the first step for crash investigators is to ensure safety and provide aid. This action is critical for multiple reasons. Firstly, the safety of all individuals involved, including victims, witnesses, and emergency responders, must be a priority. Securing the scene can prevent further accidents or injuries, particularly in cases where vehicles are still operational or traffic is flowing nearby.

Additionally, providing aid to any injured individuals is a fundamental responsibility. Investigators must ensure that medical assistance is called and rendered as necessary, attending to the health and safety of those involved before any investigative procedures can begin. The well-being of individuals takes precedence, and only once the situation is stabilized can investigators proceed with gathering evidence, interviewing witnesses, and documenting details pertinent to the crash.

In contrast, other actions like gathering witnesses or documenting evidence are important but should only occur after the scene is secured and any necessary aid has been provided. This systematic approach reflects the appropriate sequence of priorities in a crash investigation.
