What crash severity scale assigns the highest individual score to the crash?

The Maximum Abbreviated Injury Scale (MAIS) is a widely recognized tool for measuring injury severity in trauma patients. It assigns scores based on the most severe injury an individual has sustained in a crash, with a higher score indicating a more serious injury. Each level of MAIS corresponds to particular types and severities of injuries, ranging from minor (Level 1) to fatal (Level 6). By focusing on the most severe injury, it effectively represents the crash's impact on the individual and is often used in crash analysis and research to facilitate better understanding of injury outcomes and implement safety improvements.

In contrast, other scales, such as the Severity Index or Crash Severity Rating, may provide a broader or different perspective of crash characteristics, but do not necessarily assign scores based solely on the highest injury severity to one individual. The Fatality Severity Scale is even more specific as it typically addresses fatal outcomes, making it less comprehensive in assessing all injuries sustained in a crash.
