What is the second level of the five levels of a collision investigation?

• A. Reporting
• B. At-scene investigation
• C. Technical preparation
• D. Cause Analysis

Answer: (B)

The second level is the on-scene investigation, which happens right at the crash site. This phase focuses on gathering the factual picture while evidence is still fresh and accessible. Investigators document conditions, take photographs and diagrams, measure skid marks and distances, collect physical evidence, and interview witnesses. Getting these facts at the scene helps preserve accuracy before anything is moved or weather/traffic changes can alter conditions. After this on-scene data collection, technicians can plan and perform deeper analysis, leading toward determining why the crash occurred. The other options describe earlier or later steps: reporting is the initial notification and record of the incident, technical preparation involves planning and gearing up for the work, and cause analysis comes after the data has been collected and analyzed to explain the contributing factors.
