3.4 Crash Classification by Injury Severity
3.4.1 introduction: The purpose of this classification is to describe the severity of a road vehicle traffic crash in terms of injuries received. The crash is classified according to the most serious injury to any person involved.
3.4.2 categories: There are five mutually exclusive categories of injury severity for classification of road vehicle crashes. (See 2.3.1-188.8.131.52; 184.108.40.206) These may be reduced to three mutually exclusive categories by combining the nonfatal injury categories. (See 220.127.116.11)
18.104.22.168 five category set: Road vehicle crash categories, in order of precedence, are:
• Fatal injury crash (K)
• Suspected serious injury crash (A)
• Suspected minor injury crash (B)
• Possible injury crash (C)
• No apparent injury crash (O)
22.214.171.124 three category set: Road vehicle crash categories, in order of precedence, are:
• Fatal injury crash
• Nonfatal injury crash
• No apparent injury crash (also referred to as property damage only crash) (See 2.4.30)
3.4.3 general: The “no-apparent-injury crash” classification applies only to road vehicle crashes which result in damage but not injury.
