What does the KABCO scale use to categorize crash severity?

The KABCO scale utilizes a system that employs letters to represent the severity of injuries resulting from a crash. Each letter stands for a specific category, which ranges from K (fatality) to O (no injury). This method provides a quick and effective way for law enforcement and emergency responders to classify the severity of crashes when documenting incidents. Utilizing letter categories allows for a standardized approach that simplifies communication about the nature of injuries to both medical personnel and others involved in assessing the situation following a crash.

Other options, such as numerical scales, color-coded charts, or percentage systems, do not align with the established framework of the KABCO scale and therefore do not represent how crash severity is categorized in this context.
